摘要
德国哥廷根大学的M.R.Schroeder教授在1965年提出的室内声学脉冲反向积分法给我们提供了快捷和全面地测量部分声学参数的途径,为了更加科学和高效地进行各种规格的厅堂声学测试,本文基于DIRAC搭建了一套声场的无线测试系统,并就该系统在不同声场条件下的混响时间指标测试可行性和可靠性就行了验证,以便确认该套无线测试系统能够用于大型场馆的客观音质工程测试中。
Professor M.R.Schroeder who worked in Goettingen University in 1965 proposed an indoor acoustic pulse reverse integration which provides us a method to measure some acoustic parameters qucikly and comprehensively. For testing a variety of room acoustics scientifically and efficiently, this paper sets up a sound field wireless test system Based DIRAC, and make a verification about the feasibility and reliability of the system such like the reverberation time parameter under different sound field conditions which to confirm the set of wireless test system can be used for large venues objective sound engineering tests.
