Q: What is an anechoic chamber? 
A: A room without acoustics.

In the real world only large outdoor spaces can be said to be anechoic; a sound emitted in a large open space will not be reflected back to its point of origin. This kind of natural environment is impractical when making scientific measurements. Such is AMS’s commitment to research and development that it has built its own dedicated anechoic chamber, located on-site in London. 

The anechoic effect is achieved by completely covering all surfaces with specially designed sound-absorbing foam wedges. The foam absorbs sound waves from a wide frequency range, and does not reflect these back into the space which creates an acoustically ‘dead’ environment. 

Primarily the chamber is used for the testing, profiling and performance measurement of loudspeakers, microphones and Ambient Noise Sensing (ANS) systems, as well as for producing binaural recordings and auralisations. The chamber is also a valuable resource for conducting research and training. 

When working with acoustic measurements, be it of loudspeakers, sounders, or when measuring the noise created by absolutely any device, an anechoic environment is essential to assure that measurements are useful and unpolluted. Measurements in an uncontrolled environment will include the acoustic properties of the space as well as the test sample. The presence of reverberations and reflections will drastically skew results. AMS are making this valuable resource available to aid others in gaining assurance and peace of mind in their work.
