Sound Proof Chambers

Anechoic chambers are commonly used in acoustics to conduct experiments in "free field" conditions, free-field meaning that there are no reflected signals.An RF anechoic chamber is designed to suppress the electromagnetic wave energy of echoes: reflected electromagnetic waves, from the internal surfaces. Both types of chamber are constructed with echo suppression features and with effective isolation from the acoustic or RF noise present in the external environment.An anechoic chamber is a shielded space designed and constructed to resist intrusive electromagnetic waves and suppress the emission of electromagnetic waves to the outside world. Anechoic chambers originated in the early 1950s and were initially used for experiments and research on radio equipment and antennas.
