Introduction Objectives Methodology Result Discussion Conclusion


IntroductionIntroduction

Noise annoyance Negative emotional reaction towards noise Contributes to other health effects:

Physiological Psychological

Related to increase stress hormones Can be describe subjectively


Introduction Introduction

Rapid urbanization process Contributes to noise pollution

Children and teenagers Sensitive group High noise exposure at schools (Noorhalieza et al. 2001; Noor Rasfanjani 2005)

Need of a research of school environment and health effects

(Mendell & Garvin 2003)


ObjectivesObjectives

Determine factors influenced prevalence of noise annoyance among secondary students in Kota Bharu.


MethodologyMethodology

Study design: Cross sectional

June 2008 to November 2008.

Kota Bharu Target population:

All form 4 Malay students in government funded schools in the urban area of Kota Bharu.

Sampling: A conveniently selected secondary school

264 form 4 students Exclusion: Chronic diseases



Noise exposure: integrated sound level meter, Model 2238

Bruel & Kjaer Measurement based on DOE guideline

A weighted sound pressure level (dBA). Selected location

(DOE 2004)



Pretested questionnaire Modified version

Tested questionnaire used in previous study on community in Kuala Lumpur

Standard question on noise annoyance.

(Mohd Shukri 2006; Öhrström

2004)

Noise sensitivity: Weinstein Noise Sensitivity (WNS) scale.

(Kishikawa et al 2006; Staples et al 1999)


ResultsResults

The ambient sound level (LAeq) based on 3 location points.


DiscussionDiscussion

High noise level at schools near busy roads which was above the DOE limits for sensitive areas.

(Noorhalieza et al. 2001; Noor Rasfanjani 2005)

Community - higher noise level in the community expose to traffic and commercial noise up to 71.1 dB(A)

(Mohd Shukri 2006)



Higher annoyance level among students. reported high noise annoyance occurred in 14-

25% population(Belojevic et al 2003; Michaud et al 2005; Niemann & Maschke 2004).

No difference of noise annoyance/ health effects between employed parents, low socio economy family or between genders.

(Stensfeld et al 2006)



High perception of control reduced the health effects and there was a positive association between annoyance and perception of control

(Michaud 2005)

The person who coped would not be annoyed. (Jones and Chapman

1984)


ConclusionConclusion

Perception of high annoyance based on the score, was high among the secondary school children in Kota Bharu.

More studies is needed to address this problem in preventing the health effects of noise annoyance among school children.

The findings were beneficial in determining the mitigating and control measures in preventing high noise exposure especially traffic noise Buffer zone Improve present facilities.
