Anechoic Chambers, (also called acoustic chambers), are designed to provide a consistent acoustic environment for accurate data on repeated tests, including simple quality control requirements and high-precision acoustic measurements. Acoustic test chambers are available in different configurations for different tests. They are designed around the ISO Standard or to the exact needs of the client. An anechoic chamber can be considered similar to a precision acoustical measurement instrument, providing a free-field environment without noise interference or sound reflection. In an ideal free-field environment, the inverse square law would function perfectly. This means that the sound level from a spherically radiating sound source decreases by 6dB for each doubling of distance from the source. For a free field to exist with perfect inverse square law characteristics, room boundaries must have a sound absorption coefficient of unity at all angles of incidence. In practice this is usually not quite perfect and deviations from the inverse square law are to be expected.
