| 摘 要： | 在点声源、线声源的基础上,研究了圆形面声源、矩形面声源、半球声源、球声源、正方体声源的声强、声功率,建立了正方体声源的声学模型,并进行了声源辐射表面声功率的理论推导。表面声能分布不均匀声源的半消声室试验证明,按声强法声源辐射表面声功率理论得到的声功率计算结果与测量结果相符,从而提出了声源声功率测量理论。

| Abstract: | Sound intensity and sound power of disk,rectangle,hemisphere,sphere,cube were re- searched on the basis of sound source,such as point,line.An acoustics cube model was built to derivate the theory of sound power of sound radiation surface.According to the theory of sound power of the intensity method of sound radiation surface,the result corresponded with the measurement result of detailed experi- ment of uneven acoustic energy in a semi-anechoic room.Then a new theory of sound power determination of the intensity method was brought forward. |
