Main Page | See live article | Alphabetical index An Anechoic room is created to simulate what is called a free field. A free field is the representation of a theoretical infinite plan, in which no sound wave reflections, or echoes, take place. In rooms such as these, the only sounds which exist are being emitted directly from the source, and are not reflected from another part of the chamber. Anechoic rooms have the characteristic of being muted, muffled, and silent. An anechoic room is used - among others - for acoustic measurements with respect to microphones and loudspeakers\n This article is from Wikipedia.
