Comparison Of Room Acoustic Simulation Softwares

As the development of computer aided design,Using the computer to cany on the sound field simulation is an inevitable trend in the development of modernization.Using room acoustic simulation software is becoming a important part of architectural acoustics design.However,most specialist in acoustic is puzzled by the inaccuracy of room acoustic simulation software and the inconsistency of different softwares.This paper research two most popular room acoustic simulation software in china.According to the actual data of hall,we modeling it by both EASE and ODEON.For the accuracy of two model,all the sound absorption material used in this paper is measured in the reverberation chamber of Nanjing University.With the completed model of EASE and ODEON,we compare the simulation value of the reverberation time and the actual reverberation time measured in the hall at fist.Then according to ISO 3382,we choose eight index and calculate these index by both EASE and ODEON.With the comparison of these date,it shows that the ODEON simulation of reverberation time more accurate than the simulation value of EASE.Also it shows that EDT and D50 are more consistent in the eight index.
