Acoustic performance analysis of anechoic chambers based on ISO 3745 and ISO 26101: standards comparison and performance analysis of the anechoic chamber at the University of Split

Anechoic chambers are designed to provide free sound field environments for various measurement applications. Recommended procedures for anechoic and hemi-anechoic chamber performance qualifications have been defined in ISO 3745 (first version published in 1977) and the new ISO 26101 published in 2012. In this paper, we compare the two standards and their current versions and present the actual performance measurements of the newly constructed small anechoic chamber at the University of Split, Croatia. We also present and analyze the reverberation time measurements (ISO 3382) of the chamber.
