Educational Anechoic Chambers


IAC Acoustics has installed hundreds of hemi-anechoic facilities to universities, research laboratories and test houses. Our range of single and double wall construction rooms allow for high precision measurements to be carried out in a hemi-anechoic environment. Typical uses include testing microphones, hearing protection devices and hi-fi equipment. The hard, or non-acoustically absorbent floor is typically used when larger, heavier items are to be tested where a fully anechoic facility would be impractical, or when the normal mode of operation is over a reflective plane such as a floor or hard road surface.

High precision hemi-anechoic chambers from IAC Acoustics offer the same build specification as our range of fully anechoic chambers, except with a hard, isolated floating floor, rather than one lined with anechoic wedges.
