Abstract

As a continuation of the work presented in 122nd AES Convention, this paper tries to study in depth the anechoic chambers qualification. The purpose of this paper is to find parameters that allow the characterization of this type of enclosures. The proposal that becomes in this work is trying to obtain data of the anechoic chambers absorption by means of the transfer functions between pairs of microphones, or by means of the impulse response between pairs of microphones. Based on the results of the transfer functions between pairs of microphones can be checked easily agreement of the inverse squared law, allowing to determine the chamber cut-off frequency. Making a band-pass filtering it could be confirmed the anechoic chambers qualification.
