An anechoic chamber is a space that can completely absorb sound waves. The room is insulated from external noise, with wedge-shaped fiberglass wool covering the entire ceiling, floor and walls, which dissipates all the energy of the sound waves, thus completely eliminating echoes. An anechoic chamber is arguably the quietest place on earth.
For our benchmarks, we place the device in an anechoic chamber, turn up the speaker volume to test the sound pressure level, and measure the level of distortion during playback.
