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.

Acoustic chamber 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

9.71 m2

Small test panel opening

1100 wide x 1605 tall mm

Small test panel size

1000 wide x 1505 tall mm (inside clamping frame)

Volume between chambers

9.42 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 articles’ 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

9.71 m2

Small test panel opening

1100 wide x 1605 tall mm

Small test panel size

1000 wide x 1505 tall mm (inside clamping frame)

Volume between chambers

9.42 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 has aluminium floor plates that can be removed to reduce sound reflection.

The anechoic room’s specifications are:

  • 4.79 x 3.90 x 3.94 m
  • 73.6 m3.
