| 摘 要： | 本文以脉动半球声源和固定圆板的一阶振型假设为基本物理模型,导出了不同频率下的振——声转换公式,由此求出振动板上某一点处的界面声压级.然后根据平均界面声压级及空间某点的坐标,求出振动板在空间声场中该点的声压级.

| 关 键 词： | 声压级 |

| Abstract: | Abstract This paper deduces vibration-----sound exchanging formula from basic physical medel of impulser semipherical sound source and vibrating circle plate. And then its boundary surface sound pressure level of some point at different frquency is caculated. Last its sound pressure level of any opint in sonic field is infered from its average sound pressure level and its space coordinates. |
