point sound source

基本解释

The coherence of a point source sound field was also analyzed to verify the validity of the approach.
同时对点源声场的相干性也进行了验证性的分析。
Submarine is a very complex space noise source in near field, so it can't be regard as a point sound source in traditional sense.
因此研究潜艇水下辐射噪声场的空间分布特性是十分重要和必要的，对潜艇声隐身技术的发展和水中兵器的研制和开发有着重要的意义。
This paper develops a theoretical formula for calculating interfacial noise of vibrating point from its vibratory quantity with pulse semisphere sound source as basic physical model.
本文以脉动半球声源为基本物理模型，推导了由振动量计算振动点的界面噪声的理论公式。
