acoustic radiation impedance

基本解释

The relationship between the radiation impedance and the acoustic radiated power of the radiator with non-uniform vibrating velocity on the surface is formulated.
推导了表面振速分布不均匀的辐射器的辐射阻抗与辐射器辐射声功率之间的关系。
The commercial software SYSNOISE which is based on the boundary element method is used to calculate the acoustic radiated field and radiation impedance of various sources.
研究了利用基于边界元方法的SYSNOISE软件来计算各种声源的声辐射。
In this paper, the acoustic impedance caused by the sound radiation at the terminals of the aperture, which is laid on the cylindrical surface, is analysed on the base of rigorous sound theory.
本文根据严格的声学理论，分析了圆柱面上小孔端面由于辐射所产生的声阻抗率。
