Acoustic Chambers
We have three high-quality acoustic chambers available for hire, including two reverberation chambers and one anechoic chamber for facilitating sound transmission loss, sound absorption, sound power and acoustic radiation measurements.
Facilities
We have three acoustic chambers: a source room, receiver room and anechoic room.
-
Source room
The source and receiver rooms are used for testing transmission loss. The sample is installed in a hole in the wall between the two rooms. Sound in the source room then passes through the test sample into the receiver room, where the resultant sound pressure is measured by a traversing or fixed microphone(s).
The source room’s specifications are:
Dimensions
6.085 x 5.175 x 3.355 m
Volume
105.6 m3
Surface area
138.5 m2
Opening area
3.607 x 3.194 m = 11.52 m2
Small test panel opening
1.000 x 1.000 m = 1.00 m2
Volume between chambers
11.18 m3
Rotating diffuser
Hemi-conical shape
2.5m height
1.5m diameter top
3.0m diameter bottom
Swept volume 10.31 m3
-
Receiver room
The receiver room is used for acoustic transmission loss, noise reduction and insertion loss testing, and to measure sound power. The room has several static diffusers and a rotating diffuser, which is used to better disperse sound in the chamber to create a uniform sound field.
The receiver room’s specifications are:
Dimensions
6.840 x 5.565 x 4.720 m
Volume
179.7 m3
Surface area
193.2 m2 Including opening area
Opening area
11.52 m2
Small test panel opening
1.000 x 1.000m = 1.00 m2
Volume between chambers
11.18 m3
Rotating diffuser
Hemi-cylindrical shape
2.4 m height
3.5 m diameter
Swept volume 23.09 m3
-
Anechoic room
The anechoic room is used to measure objects’ acoustic radiation patterns, and when a quiet measurement environment is required. The room can be configured to be fully anechoic or have floor plates installed to create a hemi-anechoic space.
The anechoic room’s specifications are:
- 4.79 x 3.90 x 3.94 m
- 73.6 m3.
