For the purpose of this measurement a wall construction has been made into the test opening between measuring rooms (1) and (2) (figure 1 en 2). The construction exists of a separate frame covered on each side with two panels of 12,5 mm gypsum board, the wall cavity is filled with Rockwool. All seams and chinks are carefully sealed with a resilient putty.The sound insulation of this construction being such that the sound transmitted through that construction was negligible compared to the sound transmitted through the door under test.

The client built the door constructions in to the test opening. The description of the various constructions and the figures were taken from the drawings supplied by the client or by own observations.

Immediately before each of the tests the door(s) has been opened and closed five (5) times.The following door types were tested;

The results as presented here relate only to the tested items and laboratory conditions as described in this report. The laboratory can make no judgement about the representativity of the tested samples. The test report ahead is valid as long as the tested constructions and/or materials are unchanged.

4 M e a s u r e m e n t s

4.1 M e t h o d

The tests were conducted in accordance with the provisions of the test method ISO 10140-2 in the Laboratory for Acoustics of Peutz bv in Mook. A detailed description of the test set up has been given in figures 1 and 2 of this report.

The construction to be tested is placed into a test opening between two measuring rooms. In one of the rooms (the so-called sending room) loudspeakers generate broadband noise.

In this sending room as well as in the adjacent room (the "receiving room") the resulting sound pressure level is measured by means of a continuous rotating boom, so the (time- and space-) averaged sound pressure level is determined.

The reverberation time of the receiving room is also measured.

The instruments and the method used meet the requirements of ISO 10140-5.

As allowed by the test method the test procedure is repeated reversing the sending and receiving rooms. The reported value of each sound insulation is the arithmetic average of the two results.

In ISO 10140-2 the airborne sound insulation of an object is defined as the "sound reduction index R" to be evaluated according to formula 1 and expressed in dB:

(1)

in which:L1 = sound pressure level in the sending room [dB]L2 = sound pressure level in the receiving room [dB]S = area of the object to be tested [m2]A = equivalent sound absorption [m2] in the receiving room according to:

(2)

in which:V = volume of the receiving room [m3]T = reverberation time in the receiving room [s]

A 2641-1E-RA-002 8

R = L1 − L2 + 10 log( SA)

A = 0,16 VT

4.2 A c c u r a c y

The accuracy of the airborne sound insulation as calculated can be expressed in terms of repeatability (tests within one laboratory) and reproducibility (between various laboratories).

4.2.1 R e p e a t a b i l i t y r

When: - two tests are performed on identical test material - within a short period of time - by the same person or team - using the same instrumentation - under unchanged environmental conditions - the probability will be 95% that the difference between the two test results will be less than or equal to r.

In order to evaluate the repeatability r for the sound insulation measurements performed in the laboratories of Peutz bv in Mook eight series of measurements have been carried out according to ISO 140-2. From the results of those measurements the repeatability r has been calculated. It was found that for the frequency range from 100 to 250 Hz the repeatability r is 2,0 dB as a maximum. For the frequency range 315 to 3150 Hz the repeatability r is 1,3 dB as a maximum.

The repeatability r regarding the single-figure rating R w is 0,7 dB as a maximum. As ISO 717-1 prescribes rounding of the Rw-values to the nearest dB repeatability r of 1 dB is applicable for the Rw-value.

From these results it may be concluded that the repeatability r as found satisfies the demands of ISO 140-2.

4.2.2 R e p r o d u c i b i l i t y R

When: - two tests are performed on identical test material - in different laboratories - by different person(s) - under different environmental conditions - the probability will be 95% that the difference between the two test results will be less than or equal to R.

In ISO 140-2 there is a statement on the reproducibility R to be expected, based on the results of various inter-laboratory tests. The reproducibility of the single figure rating R w is about 3 dB.

The results of the measurements are given in table 4.2 and 4.3 and in figure 9 up to and including 14. In the table and graph the values of the insulation found are presented in 1/3 octave bands. From these values the weighted sound reduction index R w according to ISO 717-1 including the spectrum adaptation terms C and Ctr have been calculated and stated.Immediately before each of the tests the door has been opened and closed five (5) times.

SOUND INSULATION TEST FACILITIES

The testrooms meet the requirements of ISO 10140-5.Additional data:- volume of the receiving room: 111 m3

- volume of the source room: 94 m3

- area of the test specimen: 12,0 m2

Both rooms are isolated for vibrations by using a so calledroom-in-room construction. Flanking transmission is thus minimized.
