Abstract

Abstract

An acoustic laboratory of the Zhijiang Laboratory includes an anechoic room, a semi-anechoic room, a reverberation room and a listening room. Based on the overall layout of the experiment building, the internal structural dimensions of the acoustic laboratory were determined, and the acoustic performance design requirements were put forward, which can be used in the design and planning of similar acoustic laboratories. After the construction, the acoustic performance of the anechoic chamber, the semi-anechoic chamber, the reverberation chamber and the listening chamber was tested respectively according to national calibration specifications JJF 1147 and JJF 1143. The results show that the acoustic laboratory has achieved the expected specifications and it can provide a high-precision acoustic environment for acoustic research in the Zhijiang Laboratory.
