1·In this thesis, the study is focused on the characteristics of distributed sound source and its using in the active acoustical structure as the secondary source, including the foll.
本文为有源声学结构研究的一部分，侧重于研究分布式声源的声学特性，并对其作为次级源在有源声学结构中的应用进行了深入的研究。
2·Sound source localization is one of main functions of auditory system.
声源定位是听觉系统的主要功能之一。
3·At last the mechanism of sound source and the possibility regarded as a precursor of earthquake have been discussed briefly.
最后对声源的机制及其作为地震前兆的可能性作了扼要的讨论。
4·The acoustic holography technique for sound source identification and position by the method of continuously scanning improves the previous acoustic holography experiment.
连续扫描声全息声源识别定位技术是对以往声全息实验方法的改进。
5·Described are the sound source detection method for the aerodynamic noise on Shinkansen rolling stock and relevant noise reduction measures.
介绍了新干线车辆空气动力噪声的声源探测方法及相应的降噪措施。
