After the successful construction of the anechoic chamber, we carried out measurement according to international standards ISO 3745 and ISO 26101.
Anechoic chambers are designed to provide free sound field environments for various measurement applications and it is very important that the free-field characteristics satisfy requirements defined in international standards ISO 3745 and ISO 26101.
Actual performance measurements of a small anechoic chamber following the standard procedures thogether with the reverberation time measurements RT60 of the chamber showed that this chamber performs well, follows the inverse square law performance and achieves low reverberation times.
