This paper first shows experimentally that the distribution of modal spacings in a reverberation room is well modeled by the Rayleigh or Wigner distribution. Since the Rayleigh or Wigner distribution is a good approximation to the Gaussian orthogonal ensemble (GOE) distribution, this paper confirms the current wisdom that the GOE distribution is a good model for the distribution of modal spacings. Next this paper gives the technical arguments that the author used successfully to support the pragmatic arguments of Baade and the Air-conditioning and Refrigeration Institute of USA for retention of the pure tone qualification procedure and to modify a constant in the International Standard ISO 3741:1999(E) for measurement of sound power in a reverberation room.
本文首先通过实验表明，混响室内模态间距的分布可以很好地用瑞利分布或维格纳分布来建模。由于瑞利分布或维格纳分布是高斯正交系综（GOE）分布的良好近似，本文证实了当前的观点，即GOE分布是模态间距分布的良好模型。接下来，本文给出了作者成功用于支持巴德以及美国空调与制冷协会关于保留纯音鉴定程序的实用论点，并修改国际标准ISO 3741:1999(E)中用于混响室内声功率测量的一个常数的技术论据。
