acoustic treatment« BACK TO DICTIONARY INDEX
(n.) The materials used to change the temporal, spectral, and spatial qualities of the sound in a room. The physical tools used by an acoustician to treat a room are absorbers, reflectors, and diffusers. Absorbers attenuate sound, reflectors redirect sound, and diffusers uniformly distribute sound. Some virtual acoustic treatments can be applied to a sound by a digital signal processor after the recording.
