Anechoic Chamber

A specially designed room in which there are no reverberations of sound waves. In an anechoic chamber, there are no echoes and no room interactions. A speaker placed in an anechoic chamber is not affected by the room; it’s sound is not reinforced or diminished by the room in any way. While in real life, we do not live in anechoic environments, the anechoic chamber can be a useful testing ground for speakers. Since any time a speaker’s frequency response is measured, room interactions can interfere, an anechoic chamber can determine the true frequency response of a speaker and only that speaker. flat frequency response generated from a pure test signal is the ideal for any speaker. Speakers cannot achieve this ideal in the real world due to room interactions even if the speaker itself had a perfectly flat response. An anechoic chamber takes the room out of the equation to test the speaker itself. Since every listening environment varies, optimizing a speaker in an anechoic environment is one way of creating a speaker that will perform well in most situations (another way would be to design a speaker for a specific room or type of listening environment, but this would be nearly impossible in real life since there are so many possible environments).
