anechoic chamber

An anechoic chamber is a specially designed room that absorbs sound and electromagnetic waves, preventing reflections and external noise. Its walls are lined with materials that absorb sound waves, creating an environment similar to outer space—free from echoes and reverberations. This controlled setting allows precise testing and measurement of devices like microphones, speakers, and antennas without interference. Typically used in acoustics research and electromagnetic testing, anechoic chambers provide a highly controlled environment to ensure accurate, repeatable results in both sound and electromagnetic studies.
