本文基于统计声学理论对中断声源法进行研究,有助于听音室混响时间校准技术的应用和发展.通过分析声音在听音室中声音的衰减过程,参考国内各标准的混响时间测试方法,对各方法中的声源—工作传声器规则进行归纳,结合听音室混响时间可调且较短的特点,总结一种针对听音室校准的声源—工作传声器放置规则.在同一听音室中分别采用国内各标准方法规则和本文规则对混响时间进行比对测试.测试结果表明,采用本文规则校准听音室混响时间时,声音衰减结果更为自然,增加测试结果的准确性.
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.
