Anechoic Chambers by IAC: High-Performance Acoustic Test Facilities

Widely used in practice, free-field chambers—also known as anechoic or echo-free rooms—are specially designed test environments for acoustic measurement and sound analysis. These chambers are essential for product certification, research and development, and specialized audio recordings. Thanks to their unique acoustic properties, anechoic chambers enable a broad range of sound testing applications, as their walls, ceilings, and floors are designed to absorb nearly all sound reflections—creating an environment of absolute silence.

To achieve optimal sound absorption and minimal reflection, the acoustic impedance (the medium’s resistance to sound waves) must be as close as possible to that of air across a wide frequency spectrum.

Acoustic Testing for Industrial OEMs

IAC Acoustics has supplied some of the world’s best brands with various kinds of acoustic testing facility. From computer components to large diesel engines and generators, we can supply a solution to provide you with a certified facility for carrying out acoustic measurements and tests. From supplying acoustic lining packages to a complete turnkey facility, we can provide a cost effective solution to your testing requirements.
