Anechoic Chambers
An anechoic chamber is a structure that would create a situation of isolation and electromagnetic noise. The inner wall of an anechoic chamber is made of a polymeric material in a wedge shaped acoustic, the second layer consists of a metal panel to help shield the electric fields and the third and last layer serves to shield the magnetic fields through a system of ferromagnetic panels. The anechoic chambers are used in acoustics to measure sound pressure levels emitted by a source, so for example to ensure that the volume of the components of the household does not exceed the thresholds established by law.
