Anechoic chambers

The use of anechoic chambers is necessary to perform laboratory sound measurements in optimal conditions and therefore with maximum acoustic insulation from the external environment and with an excellent soundproofing coefficient (close to free-field).

Inside an anechoic chamber it is possible to measure absolute values which are difficult to measure in other conditions. For example,  in order to guarantee standards of comfort, the (slight) acoustic energy emitted by the components of home appliances must not exceed 25-30 dB(A).

 The minimum performance standards  of an anechoic chamber are described in ISO 3740.

The dimensions of an anechoic chamber can vary according to the volume of the source to be analysed.  Critical components of anechoic chambers are the doors, the gates and the ventilation systems, which obviously have to meet specific acoustic standards.
