| 摘 要： | 针对现代强声学技术研究的需要,从声压级的角度,对所设计的流体动力式强声发生器的性能参数开展了实验研究,得到了工作压力、簧片与喷口之间的距离以及簧片的劈角对该强声发生器辐射声场声压级的初步影响规律.实验结果表明,在较优的工况条件下,该强声发生器出口处可实现140dB(最大声压级)以上声辐射输出.

| Abstract: | For the need of modern intense acoustics technology research,the performance parameters of a hydrodynamic intense sound generator are investigated experimentally.The rules of the influences of the operating pressure,the distance between the reed and nozzle,and the angle of the reed on the SPL(sound pressure level) in the acoustic radiation field are explored and obtained.The results show that,under the optimal circumstance,the SPL in the outlet of the generator can be larger than 140dB. |
