The basoonist settled into the anechoic chamber and prepared for another grueling recording session.
1 The complete absence of reflected sound (echo) 2 An environment that prevents (through dissipation of absorption of sound waves) all reflected sound, as in an anechoic chamber
Without echo Said of an acoustic which is free field (i e without boundary or reflecting surfaces), and specifically of a room which is designed to produce no reverb or other echo effects This is achieved by making the walls with very irregular surfaces of considerable and varying depths, in such a manner as to ensure that (in theory) all sound pressure waves which strike the walls are completely absorbed Rooms of this type are used to test audio equipment such as loudspeakers and microphones and for other types of research
Echo free; an anechoic room is a room whose walls, ceiling, and floor are covered with a sound-absorbing material
Literally, without echoes Anechoic refers to the absence of audio reflections The closest thing to this situation in nature is the great outdoors, but even here there are reflections from the ground, various objects, etc It is almost impossible to create a truly anechoic environment, as there is no such thing as a perfect sound absorber At high frequencies, it is possible to create near-anechoic conditions, but the lower the frequency, the harder this is (Absorption is wavelength dependent As an example, a 100 Hz wave is about 10 feet long; the absorber must be at least 1/2 a wavelength deep to function properly It quickly becomes impractical to create a large enough space with enough material in it to absorb low frequencies)
