SOUND REDUCTION INDEX (Rw) OF A 187MM SPEEDPANEL WALL SYSTEM INCORPORATING 51MM THICK SPEEDPANEL

1. INTRODUCTION

The test described in this report was carried out at the request of Speedpanel Pty Ltd to determine the airborne sound transmission loss and the weighted sound transmission index (Rw) of a 187mm Speedpanel Wall System (750kg) incorporating 51mm thick Speedpanel.

The test has been carried out using the pair of sound transmission rooms of the School Of Electrical And Computer Engineering, RMIT University. The sample under test is mounted in the vertical aperture between a reverberant source room and a reverberant receiving room.

The sound pressure level difference resulting between these two rooms when a sound source operates in the source room is used in conjunction with the surface area of the sample and the equivalent absorption area of the receiving room to determine the airborne sound transmission loss of the sample.

Testing has been carried out in accordance with Australian Standard 1191-2002, Acoustics: Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions. The weighted sound transmission index (Rw) has been determined as specified in AS/NZS ISO 717.1-2004 Acoustics – Rating of sound insulation in buildings and of building elements, Part I: Airborne Sound Insulation.

The measuring facilities and method have been accredited by the National Association of Testing Authorities, Australia (NATA) Accreditation No. 1421, and testing has been conducted fully in accordance with those terms of accreditation.

2. TEST FACILITIES

The sound transmission suite consists of a reverberant source room volume of 115.82 cubic metres and a reverberant receiving room of volume 114.73 cubic metres. Both rooms have an irregular geometry featuring a pentagonal floor plan with no two walls parallel, and with non-parallel floors and ceilings. The rooms are constructed of 305mm reinforced concrete, supported on laminated-rubber isolators, and acoustically de-coupled from one another by a 50mm closed cell polyurethane gasket.

The irregular room shape has been chosen to assist in the production of diffuse sound fields. Such diffuseness is further enhanced:

(a) In the receiving room by the inclusion of nine fixed non-rectangular panels, suspended in the room with random orientation. Six panels each have an area of 1.44 square metres and three each have an area of 1.67 square metres. The total one-sided area of these panel diffusers is 13.65 square metres, being 55.7% of that of the largest single boundary surface (the ceiling).

(b) In the source room by inclusion of nine fixed non-rectangular polyvinyl chloride panels suspended in the room with random orientation. Four panels each have an area 1.86 square metres, the other five each have an area 1.24 square metres. The total one-sided area of these panel diffusers is 13.64 square metres, being 56.5% of that of the largest single boundary surfaces (the ceiling).

7SPEEDPANEL



The average sound absorption coefficient of the diffusers and the internal surfaces of the rooms is below 0.06 in each test frequency band.

4. PROCEDURES

Testing has been conducted in accordance with the methods of AS1191:2002 – Acoustics: Method for Laboratory Measurement of Airborne Sound Transmission Loss of Building Partitions.

Random noise is fed to a single loudspeaker placed in a corner of the source room. In each one-third octave band of centre frequency 80Hz to 5000Hz, the mean sound pressure level in each room is found by the use of microphones connected to a Bruel & Kjaer Pulse Analyser. Eight independent locations of the microphone are used in each room, with the signals temporally averaged for the sampling time of 64 seconds.

The equivalent absorption area of the receiving room is determined by measurement of the reverberation time in each one-third octave band. A loudspeaker is placed in one corner of the receiving room and 10 decays are obtained at each of the eight microphone positions, between 100Hz and 5000Hz. The microphone signal is relayed via a microphone amplifier, to the Bruel & Kjaer Pulse Analyser. The analyser is interfaced to a personal computer. A program running on the personal computer allows the determination of the reverberation time from the sound decays in accordance with AS ISO 354:2006 - Acoustics: Measurements of Sound Absorption in a Reverberation Room.

The measuring equipment has been calibrated by an external accredited calibration laboratory, and is in current calibration.

5. SAMPLE DECRIPTION

5.1 Details of Sample under Test:

The wall comprised of 51mm Speedpanel core wall with a total nominal density of 750 kg/m3

The Speedpanel core was mounted in a “C” section perimeter frame that was fixed to the test aperture using Ramset gun. Once the Speedpanel was installed the Receive Room face was sealed around the perimeter using a fire rated sealant. Appendix 1 contains further details regarding the construction of Speedpanel.

Send Room: Faced with a single layer of standard 13mm plasterboard mounted on 16mm steel channel screw fixed to the Speedpanel core at 600mm spacing. The plasterboard was screw fixed at 600mm centres on to the channel.

Receive Room: 64mm steel track and stud frame (@ 600mm centres) installed 30mm from the Speedpanel. This provided a 94 mm internal wall cavity that was filled with filled with Tontine Acoustisorb 2 (100mm polyester insulation with a nominal density of 32kg/m3). The wall was then sheeted with 13mm standard plasterboard. The plasterboard was screw fixed to the frame at 600mm centres. The perimeter and the plasterboard junctions of both faces of the wall were stopped with plasterboard stopping compound.

The total wall width was 187mm

6. RESULTS

The measured airborne sound transmission loss, R dB, at each one-third octave bandwidth of centre frequencies between 80Hz – 5000Hz is given in tabular form to the nearest decibel. The Weighted Sound Reduction Index (Rw) reference curve, in each one-third octave bandwidth of centre frequencies between 100Hz and 3150Hz are expressed in tabular form and are also represented graphically for the sample tested. There are no significant errors in transmission loss values due to flanking transmission, filler wall or background noise. The Weighted Sound Reduction Index of the sample is determined in accordance with AS/NZS ISO 717.1-2004.

The precision in the results is expressed as the 95% confidence interval in the determined sound transmission loss. The K value used to determine the 95% confidence interval is 2.365. This interval is estimated from the 95% confidence interval in each of the average source room level, the average receiving room level and the receiving room absorption/surface area of sample. These values are included in the table of results.

At the request of the client the sound transmission loss has also been determined in the 80Hz one third octave band. The 80Hz band is outside the laboratory’s accredited measurement range for AS 1191 and is not an accredited measurement.

The sound pressure level difference resulting between these two rooms when a sound source operates in the Send Room is used in conjunction with the surface area of the sample and the equivalent absorption area of the Receive Room enables determination the airborne sound transmission loss of the sample.

At the request of the Client, the 80Hz Transmission Loss (R) value has been included in the Table of Results (Table 1). This measurement is outside the laboratories accredited measurement range for AS 1191 and is not an accredited measurement.


2. TEST FACILITIES

The sound transmission suite consists of a reverberant Send Room volume of 115.82 cubic metres and a reverberant Receive Room of volume 114.73 cubic metres. Both rooms have an irregular geometry featuring a pentagonal floor plan with no two walls parallel, and with non-parallel floors and ceilings. The rooms are constructed of 305mm reinforced concrete, supported on laminated-rubber isolators, and acoustically de-coupled from one another by a 50mm closed cell polyurethane gasket.


(a) In the Receive Room by the inclusion of nine fixed non-rectangular panels, suspended in the room with random orientation. Six panels each have an area of 1.44 square metres and three each have an area of 1.67 square metres. The total one-sided area of these panel

diffusers is 13.65 square metres, being 55.7% of that of the largest single boundary surface (the ceiling).

(b) In the Send Room by inclusion of nine fixed non-rectangular polyvinyl chloride panels suspended in the room with random orientation. Four panels each have an area 1.86 square metres, the other five each have an area 1.24 square metres. The total one-sided area of these panel diffusers is 13.64 square metres, being 56.5% of that of the largest single boundary surfaces (the ceiling). The average sound absorption coefficient of the diffusers and the internal surfaces of the rooms is below 0.06 in each test frequency band.

4. PROCEDURES


Random noise is fed to a single loudspeaker placed in a corner of the Send Room. In each one-third octave band of centre frequency 80Hz to 5000Hz, the mean sound pressure level in each room is found by the use of microphones connected to a Bruel & Kjaer Pulse Analyser. Eight independent locations of the microphone are used in each room, with the signals temporally averaged for the sampling time of 64 seconds.

32 SPEEDPANEL


The equivalent absorption area of the Receive Room is determined by measurement of the reverberation time in each one-third octave band. A loudspeaker is placed in one corner of the Receive Room and 10 decays are obtained at each of the eight microphone positions, between 100Hz and 5000Hz. The microphone signal is relayed via a microphone amplifier, to the Bruel & Kjaer Pulse Analyser. The analyser is interfaced to a personal computer. A program running on the personal computer allows the determination of the reverberation time from the sound decays in accordance with AS ISO 354:2006 - Acoustics: Measurements of Sound Absorption in a Reverberation Room.




The wall comprised of 78mm Speedpanel Core wall with a total nominal density of 475 kg/m3

The Speedpanel core was mounted in a “C” section perimeter frame that was fixed to the test aperture using a Ramset gun. Once the Speedpanel was installed the Receive Room face was sealed around the perimeter using a fire rated sealant. Appendix 1 contains further details regarding the construction of the 78mm Speedpanel Core and remains the propriety property of Speedpanel Pty. Ltd..

Send Room: Faced with a single layer of standard 13mm plasterboard mounted on 16mm steel furring screw fixed to the Speedpanel core at 600mm spacing. The plasterboard was screw fixed at 600mm centres on to the channel. The perimeter and the plasterboard junctions of the wall were stopped with plasterboard stopping compound.

Receive Room: 51mm steel track and stud frame (@ 600mm centres) installed 20mm from the Speedpanel. This provided a 71 mm internal wall cavity that was filled with filled with 90mm glasswool insulation with a nominal density of 22kg/m3. The wall was then sheeted with 13mm standard plasterboard. The plasterboard was screw fixed to the frame at 600mm centres. The perimeter and the plasterboard junctions of the wall were stopped with plasterboard stopping compound.

Bulkheads: 13mm standard plasterboard bulkheads were installed on both sides of the wall. The bulkheads were 145mm deep and 160mm wide and ran the full 3750mm of the test aperture vertical span.

Both faces of the wall system were fitted with 3 standard double power points, 1 electrical switch, 2 open backed down lights mounted in the bulkhead and 1 vent opening in the bulkhead.

The total wall width was 191mm.



The testing was performed on June 18th 2012.

Figure 1 below details the construction details for the wall. Figures 2, 3 and 4 show the installed bulkhead and a close up view of the bulkhead respectively.

6. RESULTS

The measured airborne sound transmission loss, R dB, at each one-third octave bandwidth of centre frequencies between 80Hz – 5000Hz is given in tabular form to the nearest decibel. The Weighted Sound Reduction Index (Rw) reference curve, in each one-third octave bandwidth of centre frequencies between 100Hz and 3150Hz are expressed in tabular form and are also represented graphically for the sample tested. There are no significant errors in transmission loss values due to flanking transmission, filler wall or background noise. The Weighted Sound Reduction Index of the sample is determined in accordance with AS/NZS ISO 717.1-2004.

The precision in the results is expressed as the 95% confidence interval in the determined sound transmission loss. The K value used to determine the 95% confidence interval is 2.365. This interval is estimated from the 95% confidence interval in each of the average Send Room level, the average Receive Room level and the Receive Room absorption/surface area of sample. These values are included in the table of results.
