​​ETS-Lindgren's Acoustic Reverberation Chambers reflect sounds to produce a non-directional or diffuse sound field within the chamber. They are typically used for sound absorption, transmission loss, and sound power measurements. Unlike the sound pressure level produced by a device, the sound power level is a property of the device and is independent of the test environment. Reverberation chambers are also used to measure the sound absorption characteristics of materials or other items such as soft panels, screens or pieces of furniture (e.g. theater seats, chairs, and sofas). These chambers provide a diffuse-field environment that enables sound absorption tests, sound power tests, and transmission loss studies to be performed.

Key Product Information


​​Frequency Range 

ETS-Lindgren offers a wide range of standard acoustic reverberation chambers to meet client needs. Standard chamber models have low-frequency cut off points of 63 Hz, 80 Hz, 100 Hz, 125 Hz, 160 Hz, and 200 Hz. Custom chamber designs are available to meet other performance specifications.

Precision Level Testing 

ETS-Lindgren Acoustic Reverberation Chambers are designed to comply with ISO 3741 uncertainty limits for both broadband and pure tone testing.

Transmission Loss Testing 

A reverberation chamber suite with a transmission loss tunnel allows the testing of the isolation characterizations of virtually any building material according to ISO 140 and ASTM E90.

Noise Emission Testing 

A single reverberation chamber allows for noise emission testing according to ISO 3741 for both broadband and pure tone sources.
