Investigation of adequacy of the analytical model of sound field in rectangular room

Abstract

This paper used the 2D analytical model to ana-lyze the possibility to model sound field of the sound sources acting at certain frequency. The obtained results of the theoretical experiment were compared to the results of practical experiment. The adequacy of the acoustic field’s analytical model to the real acoustic field was analyzed. Results showed that using the created analytical model it is possible to model the acoustic field, produced by restricted rectangular space – the room with certain acoustical fea-tures and estimate the sound level at any point of the room.
