Based on the statistical acoustic theory,the interrupted sound source method is studied in this paper,which is helpful to the application and development of reverberation time calibration technology in listening room.By analyzing the attenuation process of sound in the listening room,and referring to the domestic standard reverberation time test methods,the source-working microphone rules in each method are summarized.Combined with the characteristics of the listening room reverberation time is adjustable and short,a sound source-working microphone placement rule for listening room calibration is summarized.The reverberation time is compared and tested in the same listening room by using the domestic standard method rules and the rules in this paper.The test results show that the sound attenuation results are more natural and the accuracy of the test results is increased when the rule is used to calibrate the reverberation time of the listening room.
