1.0 INTRODUCTION

1.1 The assessment is being carried out as a result of a proposed outline planning

application for the regeneration of Beeston Business Park for mixed use

development. The site is located just south of Beeston town centre on land off

Station Road and adjacent to Beeston Railway Station.

1.2 The report assesses the impact of the Proposed Development with regard to noise. It

describes the methods used to assess the impacts, the baseline conditions currently

existing at the site and the potentially affected noise sensitive receptors. The

potential direct and indirect impacts arising from the Proposed Development and an

example of mitigation measures required.

1.3 The assessment includes the consideration of:

information on typical existing site noise climate;

information on the noise impact upon existing and proposed residential dwellings

from site noise sources;

information and predictions on noise from demolition and construction works and

noise mitigation measures, which would be necessary to comply with current

noise standards and guidance.

1.4 The above potential noise impacts are considered in the context of the existing

ambient noise at the site, which is influenced in general by road traffic movements.

1.5 Appendix 1 provides details of technical terms within the chapter, for ease of

reference. There is also a chart showing typical everyday noise levels to assist in

understanding the subjective level of noise in terms of decibels.

1.6 The areas of the proposed mixed use development relevant to the planning

application to be considered include the following (as shown on Figure.2 attached):

Residential development on approximately 7.52 hectares of land;

Business Centre buildings of 35,000sq feet;

2 x Motor trade units each 3,500sq feet;

Retail of 4500sq feet;

Local retail food unit 4,500sq feet;



Social Club (3,500sq ft);

Medical Centre (4,000sq ft);

9 industrial units (B1,B2 & B8) 5,000sq feet per unit;

10 light industrial units/trade counters 2,500sq feet per unit;

School (0.35ha) and option of school extension (0.45ha);

Parking near railway station;

additional office parking; and

new pavilion and squash courts.

1.7 The above development would include formation of new internal roads, car parking

and associated earthworks and landscaping.

1.8 In terms of noise, the following would be considered for the assessment of impact:

Fixed Plant and Mobile Noise Sources:

Air conditioning, ventilation and refrigeration plant

Service vehicles including HGV’s.

General vehicle activities

Road Traffic Movements

Any increase in road traffic movements relative to existing residential areas

Road traffic movements relative to new residential development

Train Movements

Any increase in noise from trains as a result of new development on existing

residential development on the opposite side of the railway line

1.9 It is intended that the light industrial units and offices would operate normal working

hours typically 0700 to 1900 hours Monday to Saturday. The retail food and social

club facilities applicable to this assessment are likely to operate 0700 to 2300 hours

7 days per week.

1.10 Access to the industrial and retail elements of the site development would be via the

existing access off Technology Drive.



1.11 Access to the residential element of the development would be via access

points along Technology Drive and Trent Road.

1.12 The objectives of the survey and assessment were to provide information and

advice in respect of the following:

identify plant equipment and its location;

identify the nearest noise sensitive receptors or sites;

determine likely source noise levels;

provide information on existing background and specific site noise

levels at the nearest sensitive receptors;

provide predictions of resultant noise levels at the nearest sensitive

receptors; and

provide an example of amelioration measures to reduce noise for the

proposed development to meet appropriate noise guidance.

1.13 To establish the existence and locality of any significant site noise, the methodology

and approach includes the following:

establishing the nearest noise sensitive sites;

evaluation of typical background and ambient noise levels;

evaluation of plant noise sources in terms of typical LAeq levels;

assessment of specific noise sources in relation to appropriate guidance and

standards (e.g. BS 4142, Planning Guidance and WHO noise guidelines); and

identification of noise amelioration measures where new noise sources have

been identified as being significant or have the potential of causing a

significant increase in existing noise levels.

1.14 Information used in this assessment has been obtained from the following

sources:

2.0 ASSESSMENT APPROACH

Methodology

Legislation, Policy and Guidance

National Planning Policy Framework (NPPF) 2012

2.1 Chapter 11 of the NPPF is concerned with the conservation and enhancement of the

natural environment. It indicates at paragraph 109 that “the planning system should

contribute to and enhance the natural environment by:

…Preventing both new and existing development from contributing to or being

put at unacceptable risk from, or being adversely affected by unacceptable

levels of soil, air, water or noise pollution or land instability”….

2.2 Paragraph 123 refers directly to the issue of noise and states that “Planning policies

and decisions should aim to:

Avoid noise from giving rise to significant adverse impacts on health and quality

of life as a result of new development;

Mitigate and reduce to a minimum other adverse impacts on health and quality

of life arising from noise from new development, including through the use of

conditions;

Recognise that development will often create some noise and existing

businesses wanting to develop in continuance of their business should not

have unreasonable restrictions put on them because of changes in nearby land

uses since they were established; and

Identify and protect areas of tranquillity which have remained relatively

undisturbed by noise and are prized for their recreational and amenity value for

this reason.”

2.3 The Noise Policy Statement for England (NPSE) was published in March 2010. It

specifies the following long-term vision in policy aims: “Through the effective

management and control of environmental, neighbour and neighbourhood noise

within the context of Government policy on sustainable development:

Avoid significant adverse impacts on health and quality of life;



Mitigate and minimise adverse impacts on health and quality of life; and

Where possible, contribute to the improvement of health and quality of life.”

2.4 The NPSE introduced three concepts to the assessment of noise, which includes:

NOEL – No Observed Effect Level

This is the level below which no effect can be detected and below which there is no

detectable effect on health and quality of life due to noise.

LOAEL – Lowest Observable Adverse Effect Level

This is the level above which adverse effects on health and quality of life can be

detected.

SOAEL – Significant Observed Adverse Effect Level

This is the level above which significant adverse effects on health and quality of life

occur.

2.5 The above categories are however undefined in terms of noise levels and for the

SOAEL the NPSE indicates that the noise level will vary depending upon the noise

source, the receptor and the time of day/day of the week, etc. The need for more

research is therefore required to establish what may represent an SOAEL. It is

acknowledged in the NPSE that not stating specific SOAEL levels provides policy

flexibility until there is further evidence and guidance.

2.6 The following commentary is given on the representation of NOEL and LOAEL in

relation to existing British Standards/ International guidelines:

NOEL – Inaudibility

LOAEL – The guideline values for community noise in specific environments as set

out in table 1 of the WHO Guidelines for Community Noise 1999 and in tables 5 and

6 of BS8233: 1999 - Sound insulation and noise reduction for buildings - Code of

Practice.

2.7 The NPSE concludes how the LOAEL and SOAEL relate to the three aims listed in

paragraph 2.3 above. The initial aim relates to avoiding significant adverse effects



on health and quality of life, it then addresses the situation where the noise impact

falls between the LOAEL and the SOAEL when:

“all reasonable steps should be taken to mitigate and minimise adverse effects on

health and quality of life while also taking into account the guiding principles of

sustainable development.”

2.8 The final aim envisages pro-active management of noise to improve health and

quality of life, again taking into account the guiding principles of sustainable

development

2.9 On March 6th 2014 the Government updated the Planning Practice Guidance

(“PPG”) on noise, which provides further information in respect of new

developments which may be sensitive to the prevailing acoustic environment.

2.10 The PPG includes a table summarising the noise exposure hierarchy, based on the

likely average response. Under the heading of `perception’ the `noticeable and not

intrusive’ assessment of noise is defined as `noise can be heard, but does not cause

any change in behaviour or attitude. Can slightly affect the acoustic character of the

area but not such there is a perceived change in the quality of life’. The increasing

effect level under these conditions is deemed to be `no observed adverse effect’ and

no specific measures are required.

Former Planning Policy Guidance Note 24 (PPG24) ‘Planning and Noise: 1994

2.11 In 2012, the Government removed the existing Planning Policy Guidance on noise

relating to residential development, which was known as PPG24: 1994. We have

made reference to the former guidance as it has not been directly replaced, EHOs

still make reference to its methodology and it is useful to refer to for an indication

of what absolute noise levels are normally acceptable for new residential

development adjacent to transportation noise sources.

2.12 The introduction of PPG24, stated: “The aim of this guidance is to provide advice

on how the planning system can be used to minimise the adverse impact of noise

without placing unreasonable restrictions on development or adding unduly to the

costs and administrative burdens of business.”



2.13 PPG 24 introduced the concept of Noise Exposure Categories (NEC), which had

been derived to assist local planning authorities in their consideration of planning

applications for residential developments near transport related noise sources.

Whilst the NEC procedure was only applicable for the introduction of a new

residential development into an area with an existing noise source, it provided

information to show acceptable noise limits in planning terms, for assessing

residential development to protect amenity within garden areas. Within Annex B,

guidance was given for various types of noise sources, which include, for example,

industrial noise, commercial developments, road traffic, construction sites, aircraft

and railways. Whilst this guidance was only directly relevant to proposed new

residential development in this case, there is an allocated area for residential

development adjacent to the site and therefore it provides information on what

absolute noise levels were deemed to be acceptable for residential development

affected by transportation noise.

2.14 The level at the boundary of NEC A and NEC B was based on guidance provided

by the World Health Organisation (WHO) health criteria from 1980, which stated

that: “general daytime outdoor noise levels of less than 55dB(A) Leq are desirable

to prevent any significant community annoyance”.

2.15 The night-time noise level at the boundary of NEC A (i.e. 45dB(A) Leq8hrs) and

NEC B was also based upon the WHO health criteria, stating that: “based on

limited data available, a level of less than 35dB(A) is recommended to preserve

the restorative process of sleep”. This was based on an internal room level.

2.16 Table 2.1 below provides an interpretation of the NEC categories in terms of

granting planning permission.

Table 2.1: NEC Categories

NEC Category

Description Noise Range LAeq,T dB

A Noise need not be considered as a determining factor in granting planning permission, although the noise level at the high end of the category should not be regarded as desirable.

<55dB(A) daytime (16hr) <45dB(A) night-time (8hr) Road, rail and mixed sources

B Noise should be taken into account when determining planning applications and, where appropriate, conditions imposed to ensure an adequate level of protection.

55-63dB(A) daytime (16hr) 45-59dB(A) night-time (8hr) Road, rail and mixed sources



2.17 For noisy industrial developments the guidance referred to BS4142 Method for

rating industrial noise affecting mixed residential and industrial areas. It gives the

comment that: “The likelihood of complaints about noise from industrial

development can be assessed, where the Standard is appropriate, using guidance

in BS4142: 1990.” [Note: the standard was updated in 1997].

2.18 Further comment is made in respect of noise levels within buildings in that: “In

addition, general guidance on acceptable noise levels within buildings can be

found in BS8233: 1987.” [Note: the standard was updated in 1999 and recently in

2014]

Industrial Noise Criteria

BS4142:1997 ‘Method for rating industrial noise affecting mixed residential and

industrial areas'

2.19 BS4142:1997 is based on the measurement of background noise using LA90 noise

measurements compared to source noise levels measured in LAeq measurements.

The differential between the two measurements (once any corrections have been

applied for source noise tonality, distinct impulses etc. to establish the ‘rating level’)

determines the likelihood of complaints. If a differential of +5dB(A) is resultant, then

the standard says that the noise is of marginal significance; if the differential is

+10dB(A) then complaints are likely. Any assessment of source noise has to be

considered in context with the existing ambient noise level in terms of LAeq and

therefore must be corrected for its influence before applying any further tonal

corrections and comparing with background noise data.

BS8233: 2014 `Guidance on sound insulation and noise reduction for buildings’

2.20 The British Standard BS8233 provides additional guidance on noise levels within

buildings. These are based on the WHO recommendations and the criteria given in

BS8233 for unoccupied spaces within residential properties.

2.21 The guidance provided in section 7.7 of BS8233 provides recommended internal

ambient noise levels for resting, dining and sleeping within residential dwellings.

Table 2.2 provides detail of the levels given in the standard.

World Health Organisation (WHO) Guidelines for Community Noise: April 1999

2.22 This document provides further updated information on noise and its affects on the

community. Within the document for noise ‘In Dwellings’ it states that: “The effects

of noise in dwellings, typically, are sleep disturbance, annoyance and speech

interference. For bedrooms the critical effect is sleep disturbance. Indoor guideline

values for bedrooms are 30dB LAeq for continuous noise and 45dB LAmax for single

sound events. Lower noise levels may be disturbing depending upon the nature of

the noise source. At night-time, outside sound levels about 1 metre from facades of

living spaces should not exceed 45dB LAeq, so that people may sleep with bedroom

windows open. This value was obtained by assuming that the noise reduction from

outside to inside with the window open is 15dB. To enable casual conversation

indoors during daytime, the sound level of interfering noise should not exceed 35dB

LAeq. To protect the majority of people from being seriously annoyed during the

daytime, the outdoor sound level from steady, continuous noise should not exceed

55dB LAeq on balconies, terraces and in outdoor living areas. To protect the

majority of people from being moderately annoyed during the daytime, the outdoor

sound level should not exceed 50dB LAeq. Where it is practical and feasible, the

lower outdoor sound level should be considered the maximum desirable sound

level for new development.”

2.23 In 2009, the World Health Organisation published ‘Night Noise Guidelines for

Europe’, which it describes as an extension to the WHO ‘Guidelines for community

noise’ (1999). It concludes that: “Considering the scientific evidence on the

thresholds of night noise exposure indicated by Lnight,outside as defined in the

Environmental Noise Directive (2002/48/EC), an Lnight,outside of 40dB should be the

target of the night noise guideline (NNG) to protect the public, including the most

vulnerable groups such as children, the chronically ill and the elderly. Lnight,outside

value of 55dB is recommended as an interim target for those countries where the

NNG cannot be achieved in the short term for various reasons, and where policy-

makers choose to adopt a stepwise approach.”



BS5228: 2009 ‘Code of practice for noise and vibration control on construction and

open sites’

2.24 BS5228 refers to: ‘the need for the protection against noise and vibration of

persons living and working in the vicinity of, and those working on, construction and

open sites. It recommends procedures for noise and vibration control in respect of

construction operations and aims to assist architects, contractors and site

operatives, designers, developers, engineers, local authority environmental health

officers and planners.” Part 1 deals with noise in terms of background legislation

and gives recommendations for basic methods of noise control relating to

construction and open sites where significant noise levels may be generated. There

is no specific guidance on achieving absolute noise levels or specific noise criteria,

but the guidance is aimed at giving advice on achieving ‘best practice’ in controlling

noise and vibration from construction and open sites. Part 2 of BS5228 deals

specifically with vibration control and provide the legislative background to the

control of vibration and recommendations for controlling vibration at source and

management controls (i.e. liaison with communities, supervision, preparation and

choice of plant etc.).

Road Traffic Noise

2.25 No guidance is given in PPG24 on assessment of increased traffic noise from

existing roads as a result of traffic generated by new developments. Furthermore,

noise generated by traffic on the public highway as a result of a particular

development is not considered to be the responsibility of the promoter of that

development. However, any change in noise levels along affected roads is relevant

to future planning applications.

2.26 The only guidance that refers to impacts from road traffic noise increase relates to

the Design Manual for Roads and Bridges (DMRB) Volume 11, Section 3, Part 7

(HA213/11): November 2011 which provides advice on noise and vibration. The

procedure for assessing noise impacts advises the use of a LA10 measurement

index based on an 18 hour time period (i.e. 0600 to 2400 hours). Further

assessment of the impact would be required where changes of 1dB(A) or more are

expected in the short-term and changes of 3dB(A) in the long term. Section 3.37

provides an example of the magnitude of impact for different changes in noise level



for the short-term and long term situation. Tables 3.1 and 3.2 within Part 7 of DMRB

is provided below, represented as Table 2.3 and 2.4.

3.0 BASELINE CONDITIONS

Survey Technique

3.1 The background noise survey was carried out in accordance with BS4142: 1997 and

advice given in BS7445: 2003 `Description and measurement of environmental

noise’.

Baseline Conditions

3.2 A detailed environmental noise survey was carried out at the site to determine

details of the noise climate at the nearest residential properties to provide typical

background noise data. The site inspection and detailed baseline survey was

carried out on Wednesday 9th to Thursday 10th October 2013.

3.3 Static noise measurements were undertaken at nearest receptor locations to

establish typical background noise levels relative to the existing noise climate.

3.4 Following consultation with the Senior EHO at Broxtowe Borough Council, the

areas surrounding the site were examined and the following suitable locations for

static noise monitoring were established:

Position 1: This monitoring location was at the boundary of the car park of ATOS on

land to the rear where proposed residential development is proposed off Grassy

Lane northeast of the site. This position gives an indication of typical ambient and

background noise levels for the front façade of proposed properties along the

boundary with the existing business offices.

Position 2: Position 2 monitoring location was at the northern boundary of the site

adjacent to the access road onto the business park and the railway line. The nearest

existing receptor to the railway line is on the recently developed residential site off

Wharton Crescent on the opposite side of the railway line.



Position 3: Position 3 was towards the centre of the site at the western edge of the

proposed residential development opposite SMS and approximately 160 metres

from the railway line.

Position 4: Position 4 monitoring location was at the south western corner of the site

at the closest approach to the commercial offices.

3.5 It is considered that the above noise monitoring positions provides a good cross-

section of noise levels across the site at the most sensitive existing and proposed

residential areas relative to the development. This opinion is based on subjective

observations and objective evidence during the site inspection of the surrounding

area.

3.6 The noise monitoring positions are indicated on Figure 1. Three of the noises

monitoring positions are representative of proposed residential property positions.

3.7 The fixed monitoring positions provide us with broadband noise data of the existing

noise climate around the site at the nearest residential properties.

3.8 The noise monitoring exercise was generally carried out on a weekday period to

establish typical average ambient noise climate and peak road and train movement.

Details of the instrumentation used for the survey are detailed in Appendix 2.

Consultations

3.9 In the preparation of this assessment, contact was made with Environmental Health

Officer at Broxtowe Borough Council with regard to nearest sensitive receptors,

proposed noise monitoring methodologies and appropriate noise criteria.

Site Baseline Noise Survey

3.10 The results of average measurements taken at the fixed monitoring positions at site

are presented below in Tables 3.1 to 3.2 and detailed measurements in

3.12 From the results of the background noise survey and observations at the nearest

residential receptors, it is clear that the noise climate is dominated by local and

distant road traffic noise and intermittent train noise.

Baseline Conditions - Conclusion

3.13 The existing noise levels at site indicate that the majority of the proposed residential

development (during the daytime) falls within NEC `A’ except those areas of the

proposed residential site closest to the central western boundary opposite the main

industrial units. During night-time periods the results show that the site falls

currently falls within NEC `B’ within the proposed residential area. Refer to

Appendix 5 noise map 1.

3.14 Taking into account the changes in road traffic flows and the demolition of existing

industrial units, the results show that during daytime the NEC levels would generally

fall within NEC B across the site. During night-time, the corresponding noise levels

would also fall within NEC B. Refer to noise map 2 in Appendix 5.

3.15 In terms of background and residual noise levels at the proposed and existing

residential positions we have established the following typical ambient noise levels

4.0 ASEESSMENT OF IMPACTS

Construction Noise:

4.1 Initial site preparation works is likely to involve the demolition of existing buildings,

movement of soils and the construction of new buildings and infrastructure. It is

considered that dozers, excavators, haulage lorries, piling rigs, cranes, dumpers,

concrete mixers, diggers and paving machines would all, at some time during the

construction programme, be operating at the site. In addition, ancillary equipment

such as small generators and compressors may also be operating on occasions

during the construction period.

4.2 The above noise sources and their associated activities would vary from day to day

and may be in use at different stages of the proposed development for relatively

short durations. The noisiest activities are expected to be generated during

demolition, soil movement and piling work during the initial stages of the

development when excavators, piling rigs, dozers or similar may be in use.

4.3 The actual noise level produced by construction work would vary at the nearest

property boundary at any time depending upon a number of factors including the

plant location, duration of operation, hours of operation, intervening topography and

type of plant being used.

4.4 Detailed below is an indication of the highest likely noise levels at the nearest

receptors during different site activities. The calculations use the calculation

methodology given in BS 5228-1: 2009.

4.5 The results of calculations (excluding mitigation measures) are shown below in

Table 4.1.

4.6 For the development, the highest noise levels are likely to be created during site

demolition, preparation, infrastructure and building activities. The movement of soil

may be part of the initial site preparation works and it is unlikely that any other

significant sources of noise would be present on the site while these activities were

being carried out. Piling (if required) is likely to relate to work required for the new

business centre buildings.

Note: The highest predicted noise levels are based on the noisiest plant positioned at the closest point to the receptor, this is unlikely to occur for long periods of time.

4.7 The increase in noise, as a result of construction, is likely to result in some

significant noise levels for short-term peak noise periods. The general noise levels

would not be significantly higher than typical residual noise levels, peak levels will

occur when noisy activities are at close approach to existing residential receptors

(e.g. during demolition, soil movement and building construction if using power tools

or road construction activities).

4.8 Construction noise is a temporary source and therefore would normally be limited to

a moderate impact. The application of applying best practice in accordance with BS

5228: 2009 will assist in minimising impact from construction noise.



Impact on Existing Residential Receptors from Train Noise Due to New Buildings

4.9 The Local Authority Senior EHO requested information on the likely impact from

potential reflective noise from the proposed new buildings on the Business Park

adjacent to the railway line on existing residential receptors north of the line.

4.10 Noise prediction calculations using CadnaA noise modelling software which

includes reflective components to calculate the expected increase on the opposite

side of the railway line. Refer to Appendix 5 for noise prediction mapping results.

4.11 The following table provides the results of the noise prediction calculations relative

to receptor positions. Noise levels are predicted at first floor window positions for

the highest likely impact during night-time periods.

Table 4.2: Noise prediction results for reflective noise from railway line

5. Existing residential receptors north of railway line (Cartwright Way)

50.7-53.6 51.2-54.1 0 to +0.5

4.12 The results indicate a negligible change in noise levels as a result of the new

buildings along the northern boundary of the Business Park. An increase of only

+0.5dB LAeq would be imperceptible as a change in noise and therefore not deemed

to be significant. The design layout of the light industrial and office buildings has

taken this issue into account to minimise reflection.

On-site & Off Site Road Traffic Movements Retail, Commercial & Light Industrial Units

4.13 According to BWB Consulting the road traffic movements associated with the re-

development of the business site when compared with the existing traffic flow along

the entrance to the site is likely to result in a slight increase in traffic overall,

however the number of HGVs is slightly reduced. We have calculated the likely



change in noise levels using CRTN methodology and we conclude that there would

be no change in perceived noise levels relative to existing residential properties on

the opposite side of the railway line.

4.14 The introduction of the proposed residential element of the development is likely to

generate slightly more traffic movement in specific residential areas but this is not

expected to be significant due to the number of movements and on-site inherent

screening from new dwellings.

4.15 Noise levels increases on the local road network is not expected to generate any

significant increase in accordance with appropriate guidance (i.e. DMRB calculation

methodology using CRTN calculations).

4.16 Any slight increase in road traffic movements around the retail and commercial

areas would be limited by suitable design and layout proposed (i.e. car park

screening and orientation of dwellings etc.).

Fixed Plant Noise

4.17 The impact of any associated refrigeration, air conditioning or ventilation plant for

the retail, commercial and light industrial development will need to be assessed to

determine the impact on existing and new residential areas. The main area of any

potential new plant would be associated with the retail, social club, medical centre

and new commercial and light industrial unit areas which are located at the north

western to north eastern land areas.

4.18 The results of prediction calculations with plant noise levels assumed to be

70-75dB(A) @ 1m, which is likely to be the highest likely based on empirical data.

For the purpose of the calculations we have allowed for plant to be located on all

the roof areas of the retail, light industrial and commercial units around the site. The

predicted noise contribution at the nearest receptors is provided below in Table 4.3

below. For night-time periods we assume only retail (food) and social club plant is

operating.

4.19 The fifth column in Table 4.3 shows the difference between the predicted site noise

and typical background noise at the receptor positions. The site would be designed

to eliminate any unusual noise characteristics. The rating level in column 5 is

therefore in accordance with the methodology found within BS 4142: 1997, which is

the most relevant noise criterion. The predicted noise levels indicate complaint likely

at the north eastern and west to south western edge of the new development and

existing properties at the east and north east boundaries of the site. Further noise

limits for the plant located at new buildings are provided in section 5.0 to reduce the

cumulative effect of noise levels.

Existing Industrial Noise – SMS, Siemens & ATOS

4.20 During the noise study we have undertaken noise measurements adjacent to

existing industrial units located along the western and northern boundary of the site.

Subjective observations indicate low level noise from the roof of these buildings

from service plant. Plant noise from SMS was shown to occur during the daytime

and noise from the Siemens plant was only just audible at times. The plant noise at



ATOS was more noticeable at locations in-line or forward of the nearest eastern

facade (i.e. at the furthest edge of the proposed north-east residential development

land area, refer to Figure 3).

4.21 The results of measurements taken of the low level impacts using BS4142

assessment is provided below in Table 4.4 to 4.6:

4.22 The above table shows that according to the British Standard noise levels from the

existing industrial units at the nearest proposed residential development would

show that noise is unlikely to give rise to complaint or is of marginal significance.

Further advice in terms of the design of the residential development to minimise the

likelihood of complaint is provided.



5.0 MITIGATION AND ENHANCEMENT

5.1 Construction Noise:

5.1.1 In accordance with BS 5228, best practical means would be employed to control the

noise generation (e.g. using equipment that is regularly maintained, where

practicable use equipment fitted with silencers or acoustic hoods).

5.1.2 In consideration of the likely highest levels of construction noise, the following

approach would be incorporated in the detailed design:

Restriction of construction hours to non-sensitive times of day would normally

form part of the planning consent conditions.

Sensible routing of the construction plant to avoid the nearest residential

properties.

Careful choice of piling rigs to minimise noise.

Maximise distance between any significant noise source and residential

receptor locations.

Plant switched off when not in use.

Screening of any sensitive property boundaries adjacent to the site boundary

where noisy activities are likely to occur. The use of 2 to 3 metre high hoarding

at residential property boundaries can provide a reduction in noise level of

between 5dB(A) and 10dB(A).

5.2 Proposed Light Industrial Units (western to south western end of site)

5.2.1 The design, orientation of buildings and location of any fixed plant are important in

terms of noise generated at the nearest proposed residential areas at the western

end of the site. The following design features would assist in minimising noise

generated at the residential property areas:

a) Where practicable industrial units adjacent to residential areas to be orientated

with frontages facing the railway line. Where this is not practicable, the design

layout of residential dwellings to consider having a continuous block of housing

fronting the direction of industrial units (e.g. town houses or apartments) so that

garden areas are self-screened by the dwellings.



b) The internal design of these front rows of housing to consider having less-

sensitive rooms at the front of the house (e.g. kitchens, bathrooms and smaller

bedrooms). Any bedrooms at the front rows that have to face these directions

could consider optional mechanical ventilation so that windows do not need to

be opened.

c) Any fixed plant (e.g. air conditioning, extract systems) to be located (where

practicable) at the façade of the building facing the direction of the railway line

so that the industrial building provides self-screening of plant noise in the

direction of residential dwellings to the east and southeast.

d) Where fixed plant has to be located at roof level or on sensitive sides of the

buildings then noise levels should be limited to 55dB(A) Leq at 1m. Noise levels

for plant located on building facades facing the railway line to be limited to

60dB(A) @ 1m.

e) Where practicable, doors into the industrial units to face inwards away from the

direction of existing or proposed housing.

f) Construction of industrial units to be constructed from solid walls (e.g.

brickwork) or with insulated cladding having a minimum Rw = 35dB.

g) Avoid any noisy activity outside of the buildings.

h) Avoid any openings in the buildings unless acoustically treated.

5.3 Business Offices, Medical Centre, Retail & Local Retail Units (north east to

northern end of site)

5.3.1 Similar to the industrial units along the western to south western end of the site, the

new units proposed for the northern end would need suitable design and controls to

ensure any proposed or existing residents amenity are protected. Design features to

be considered include the following:



a) Any fixed plant (e.g. air conditioning, extract systems) to be located (where

practicable) at the northern end of the buildings (excluding new business offices)

so that the building provides some degree of self-screening of plant noise in the

direction of residential dwellings.

b) Fixed plant noise levels should be limited to 55dB(A) Leq at 1m. Noise levels for

plant located at roof of new business office buildings to be limited to 60dB(A) @

1m.

c) Car parking area boundaries that are close to proposed or existing residential

receptors should be fitted with an acoustic screen which could be formed from

close-boarding fencing or similar solid screen of approximate height 2.1m

(minimum mass of 10kg/m2).

d) New office building plant to be located on roof of building.

e) Construction of industrial units to be constructed from solid walls (e.g.


f) Avoid any noisy activity outside of the buildings.

g) Avoid any openings in the buildings unless acoustically treated.

5.4 Existing Business Offices, Social Club & Motor trade Units (north to north east

end of site)

5.4.1 In terms of residential areas adjacent to the existing business unit it will be

necessary to have the dwelling frontages facing the office building and wherever

practicable have a continuous block of housing (e.g. town houses or apartments) so

that garden areas are either not required or self-screened by relatively high

dwellings. The internal design of these front rows of housing to consider having less-

sensitive rooms at the front of the house (e.g. kitchens, bathrooms and smaller

bedrooms). Any bedrooms at the front rows that have to face these directions could

consider optional mechanical ventilation so that windows do not need to be opened.



5.4.2 Mitigation measures relating to the Social Club would include:

a) Social club activities involving `live’ or amplified music to be controlled by

entertainment licence conditions (as appropriate).

b) Fixed plant noise levels should be limited to 55dB(A) Leq at 1m.

c) Construction of social club to have consideration of the control of noise `break-

out’ (i.e. control noise from doors, windows, roof areas and ventilation or

extraction areas of the building).

d) Avoid any noisy activity outside of the building.

e) Avoid any openings in the building unless acoustically treated.

f) New dwellings facing the direction of the social club to have frontages facing

this direction.

5.4.3 Control of noise from the Motor Trade units located at the north east end of the site

would require similar mitigation to that detailed in section 5.2, namely:

a) Where practicable, the design layout of residential dwellings opposite the units

to consider having a continuous block of housing fronting the direction of

industrial units (e.g. town houses or apartments) so that garden areas are self-

screened by the dwellings.

b) Fixed plant to be designed to achieve a noise level of 55dB(A) Leq at 1m.

c) Where practicable, doors into the industrial units to face inwards away from the

direction of existing or proposed housing.

d) Construction of industrial units to be constructed from solid walls (e.g.


e) Avoid any noisy activity outside of the buildings.

f) Avoid any openings in the buildings unless acoustically treated.



5.5 Existing Industrial Noise

ATOS

5.5.1 Noise associated with the ATOS offices was shown only to be significant in the

proposed most northern residential land area. The nearest proposed residential

development is north of Grassy Lane. As previously advised (in section 5.4.1) we

would advise from a design perspective that dwelling frontages facing the ATOS

office building wherever practicable to have a continuous block of housing (e.g. town

houses or apartments) so that garden areas are either not required or self-screened

by relatively high dwellings.

SMS Electronics & Siemens

5.5.2 Noise from plant located at higher level at SMS and Siemens business units is of

marginal significance. To minimise the impact on proposed residential development

it will be important to ensure the design of the dwellings and orientation is

appropriate. For this we would advise the following features to be considered in the

detailed design:

a) Housing facing the existing industrial units (i.e. southwest) to have their

frontages facing this direction with the service road between the housing and the

industrial units. This will ensure any rear gardens are self- screened by the

dwellings. The internal design of these front rows of housing to consider having

less-sensitive rooms at the front of the house (e.g. kitchens, bathrooms and

smaller bedrooms). Any bedrooms at the front rows that have to face these

directions could consider optional mechanical ventilation so that windows do not

need to be opened and as precaution for any change in industrial noise in the

future.

5.6 Proposed New Housing

5.6.1 Measures to control new fixed plant and business units have been considered and

proposed mitigation advised in preceding paragraphs (i.e. section 5.2. to 5.5). The

design of new housing and dwelling orientation has also been provided above. Any

private garden areas should include standard 1.8m high acoustic screening via

close-boarded fence screens (minimum mass of 8kg/m2).



5.6.2 Whilst no significant noise has been identified at the retained industrial units located

at the far western and eastern ends of the site, consideration of the design layout

has been undertaken to ensure that those properties closest to the industrial area

are protected. In terms of mitigation relating to the glazing and ventilation of

proposed housing we have provided below an example of configuration that would

provide adequate protection of occupants from road traffic, train noise peaks and

industrial noise sources. This is in accordance with `good‘ design range according

to BS8233: 2014.

5.7 Fixed Plant Noise

5.7.1 The Local Authority are able to impose planning conditions on any planning

permission to ensure that the proposed Local Authority noise limits for fixed plant

operation during daytime and night-time is achieved.

5.7.2 The control of noise from fixed plant can be achieved by careful selection of

equipment having a low noise output or by controlling the plant by fitting appropriate

acoustic enclosures and/or silencers to the system.



5.7.3 The predicted noise levels from the site have been calculated with the proposed

noise limits in place to ensure that the resultant noise levels are within appropriate

guidance and standards and the effect of cumulative noise is minimised i.e.:

a) Fixed plant noise levels (i.e. air conditioning, ventilation, refrigeration plant)

should be limited to a noise level of 55dB(A) to 60dB(A) Leq5min at 1 metre. The

resultant noise level with the control measures at nearest receptors is provided

below in Table 5.2.

according to the standard complaint would be highly unlikely.



6.0 SUMMARY & CONCLUSIONS

6.1 Introduction

6.1.1 Noise levels have been considered and assessed during the construction and

operational phases of the proposed development. Relevant and appropriate noise

guidance and standards have been used to determine the impact. The assessment

has been undertaken to inform and guide the design of the development such that

any likely noise impact on existing or proposed dwellings is minimised.

6.1.2 To establish any likely impact from noise a baseline noise survey was undertaken

to establish the existing noise climate at the nearest receptors to the site.

6.1.3 The Senior Environmental Health Officer at Broxtowe Borough Council has been

formally consulted for the assessment to seek advice in respect of appropriate

noise criteria, receptor locations and discussion on industrial noise sources in the

area.

6.2 Baseline Noise Conditions

6.2.1 In accordance with relevant planning policy guidance on noise the existing average

background noise levels at the nearest receptors have been established during

weekday operating periods.

6.2.2 Subjective observations at nearest residential properties indicate that intermittent

noise from local and distant road traffic, intermittent train movements and activities

on the existing business units form the general noise climate at the nearest

receptors.

Likely Effects

6.2.3 During the construction phase there would be a variety of noise sources in use at

different stages and their associated activities would vary from day to day. The

highest noise levels relative to nearest receptors are likely to occur during site

preparation, demolition and building construction activities. The peak noise

activities do not normally occur over long periods of time and best practical means

would be employed to control the noise being generated.



6.2.4 The assessment of fixed plant noise sources has been undertaken and advice

provided in respect of noise mitigation measures to ensure that these noise sources

are in accordance with relevant guidance (e.g. BS4142). Careful detailed design of

the proposed housing development in relation to orientation of dwellings, screening

and appropriate glazing & ventilation systems would ensure the protection of

occupants from external noise sources. The location and noise limits on new fixed

plant associated with proposed light industrial, retail and commercial development

would ensure complaint was unlikely at nearest sensitive receptors.

6.2.5 The assessment of reflected noise associated with train movements along the

northern boundary and the interaction of new building along this side of the site has

been assessed using computer based noise modelling. The results would indicate

that the increase in noise level would be very low and imperceptible as a change in

noise level. To minimise any reflection, the orientation of buildings along the railway

line boundary has been considered in the design of the site.

6.2.6 Acoustic screening of some of the car parking areas and orientation of light

industrial units where they are relatively close to existing or proposed residential

development can be introduced to minimise noise from vehicle movements and

activities in these areas.

6.2.7 In summary, the assessment highlights the noise issues relating to the development

and provides advice on design features and noise control techniques that can be

introduced to minimise the noise impact on sensitive receptors such that the noise

levels are within appropriate guidance and standards and occupants of dwellings

would be suitably protected against site noise generation or existing noise sources

on and off site.

APPENDIX 1

BASIC ACOUSTIC TERMINOLOGY

Sound is produced by mechanical vibration of a surface, which sets up rapid

pressure fluctuations in the surrounding air.

Between the quietest audible sound and the loudest tolerable sound there is a

million to one ratio in sound pressure level. It is because of this wide range that a

noise level scale based on logarithms is used in noise measurement. This is the

decibel or dB scale.

Audibility of sound covers a range of about 0 to 140 decibels (dB) corresponding to

the intensity of the sound pressure level. The ability to recognise a particular sound

is dependent on the pitch or frequencies present in the source. Sound pressure

measurements taken with a microphone cannot differentiate in the same way as the

ear, consequently a correction is applied by the noise measuring instrument in order

to correspond more closely to the frequency response of the ear which responds to

sounds from 20 Hz to 20000 Hz. This is known as 'A weighting' and written as

dB(A).

The use of this unit is internationally accepted and correlates well with subjective

annoyance to noise.

The logarithmic basis of noise measurements means that when considering more

than one noise source their addition must be undertaken in terms of logarithmic

arithmetic. Thus, two noise sources each of 40 dB(A) acting together would not give

rise to 40 + 40 = 80 dB(A) but rather 40 + 40 = 43 dB(A). This 3 dB(A) increase

represents a doubling in sound energy but would be only just perceptible to a human

ear.

The attached chart gives typical noise levels in terms of dB(A) for common

situations.

Noise levels can vary with time according to source activity and indices have been

developed in order to be able to assign a value to represent a period of noise level

variations and to correspond with subjective response.



The definition in layman’s terms is given below for terminology used in the

measurement and results obtained during the survey work.

A-weighting: Normal hearing covers the frequency (pitch) range from about 20Hz

to 20,000 Hz but sensitivity of the ear is greatest between about 500Hz and 5000Hz.

The "A-weighting" is an electrical circuit built into noise meters to mimic this

characteristic of the human ear.

Ambient noise: The totally encompassing sound in a given situation at a given

time usually composed of sound from many sources near and far.

Attenuation: Noise reduction

Background noise: The general quiet periods of ambient noise when the noise

source under investigation is not there.

Decibel (dB): The unit of measurement for sound based on a logarithmic scale.

0dB is the threshold of normal hearing; 140dB is the threshold of pain. A change of

1dB is only detectable under controlled laboratory conditions.

dB(A) [decibel A weighted]: Decibels measured on a sound level meter

incorporating a frequency weighting (A weighting) serves to distinguish sounds of

different frequency (or pitch) in a similar way to how the human ear responds.

Measurements in dB(A) broadly agrees with an individual's assessment of loudness.

A change of 3dB(A) is the minimum perceptible under normal everyday conditions,

and a change of 10dB(A) corresponds roughly to doubling or halving the loudness of

sound.

dB(C): [decibel C weighted]: Frequency weighting which does not alter low

frequency octave band levels by very much compared to `A' weighting. Similar to

linear reading (i.e. linear does not alter frequency spectra at all)

Frequency (Hz): The number of sound waves to pass a point in one second.



LAeq: This is a noise index used to describe the "average" level of a noise that

varies with time (T). It allows for the different sensitivities of the human ear to

different frequencies (pitch), and averages fluctuating noise levels in a manner,

which correlates well with human perceptions of loudness.

LA10,T: This noise index gives an indication of the upper limit or peak levels of the

fluctuating noise. It is the "A weighted" noise level exceeded for 10 per cent of the

specified measurement period (T). e.g. If the measurement period was over 10

hours and the LA10 reading was say 60dB, then this means that for 1 hour out of 10

the level went above 60dB.

LA90,T: This noise index gives an indication of the lower limit or levels of the

fluctuating noise. It is the "A weighted" noise level exceeded for 90 per cent of the

specified measurement period (T). e.g. If the measurement period was over 10

hours and the LA90 reading was say 50dB, then this means that for 9 hours out of

10 the level went above 50dB.

LAmax: This is the highest A weighted noise level recorded during a noise

measurement period.

Residual noise: The ambient noise remaining at a given position in a given

situation when the noise source under investigation is not there.

Specific noise: The noise source under investigation for assessing the likelihood of

complaints

Norsonic Real Time Analyser 118 June 2014 31992

Cirrus Electronic Calibrator CR: 513A June 2014 031692

The following set-up parameters were used on the sound level meters during noise

measurement:

Static Noise Monitoring:

Time Weighting: Fast

Frequency Weighting: `A’

Measurement Period: 15 minutes (spot roaming generally 15 minutes and 1 minute)

Calibration

Calibration setting: 94dB

The noise meters were calibrated with the electronic calibrator prior to commencement

and on completion of the survey. No significant drift in calibration was observed.

Survey Dates and Personnel

Static noise measurements positions (shown on figure 1) were chosen following liaison with

the Senior EHO at Broxtowe Borough Council to carry out noise monitoring around the site to

establish typical ambient noise data (see Appendix 3 for detailed information). Mr. D.R.

Kettlewell and Mr P Lycott of Noise & Vibration Consultants Limited carried out the noise

monitoring measurements.



Monitoring Period and Test Details

Baseline Survey

Measurements were recorded over a 24 hour period during a weekday. Data logging of LAeq,

LA10, LA90 and LAmax were recorded at 15 minute intervals for information on the variation of

typical noise levels at nearest receptor locations.

The noise meters were mounted on a tripod at a height of between 1.2 to 1.5 metres above

ground level and fitted with a wind and rain shield.

Meteorological Conditions

Weather details were recorded by the NVC engineer during the period of the surveys, and

appear below:

Wednesday 9th – Thursday 10th October 2013

During the daytime it was dry, variable cloud cover and a light west to north-west wind (1-

3m/s) a temperature of 7-13deg C. The night-time period remained dry, scattered cloud with

light north westerly winds (1-3m/s). Temperature around 7-8deg C.

The above climatic conditions were suitable for monitoring environmental noise levels in

accordance with advice given in BS 7445:2003 `Description and measurement of

environmental noise’.
