The Simulation and Experimental Research on Reverberation Time in Car Speaker Sound Field


Article Preview

As an important element of the index in room acoustics, the reverberation time has been considered as an objective parameter with clear concept and had good correlation with the subjective perceptions in the field of psycho-acoustic criteria. Through the computer acoustic simulation software EASE and the electro-acoustic test system CLIO, this paper conducts research on the reverberation time of the car speaker sound field, which in the domestic car of a certain type, studies show that EASE is accurate and reliable in the simulation of the car speaker sound field, the reverberation time is greater than 0.4s when the frequency less than 500 HZ and less than 0.1s when the frequency greater than 1000 HZ, when reaches to 500 HZ, the reverberation time reaches the maximum 1.103s.
