摘要
本文通过实验测量分析小雨滴、中雨滴、大雨滴、极大雨滴四种不同粒径雨滴的声辐射,从而确定雨致噪声的关键因素是初始冲击声和气泡脉动声。通过对气泡脉动声进行分类,并对其激发机制进行分析,从而研究了初始冲击声辐射和气泡脉动声辐射的特性。然后通过模拟降雨器产生不同粒径及其组合的多雨滴,使用混响法来对雨滴的水下噪声特性进行空间平均测量,给出多雨滴的水下噪声统计特性。最后,对降雨量与雨滴噪声的关系进行量化分析,完成对降雨量的反演。
The radiation noise for four different kinds of raindrops was analyzed and the sound radiation mechanisms and the key term that influence on the rainfall noise were determined. The rainfall noise was classified and the generating mechanism was also determined, so the characteristics of sound radiation from impact and from bubble trapped can be identified. Multiple raindrops are generated with different speed by the rainfall simulator. Due to the low precision from traditional rainfall noise measurement method, the reverberation was proposed to measure the underwater noise for different rainfall. The noise of these raindrops was measured by this method and their sound levels were gotten by hydrophones' spatially averaging, so the underwater noise characteristics of raindrops can be determined. For the splashed down raindrops' bubble noise lack of quantitative description problem, a quantitative models for bubble acoustic characteristics were put forward applicable to the rain, so the rainfall can be inversed by rainfall noise measurement.
