作为次声技术研究的核心技术,次声源的发展决定了次声技术的整体进程。管式声源和活塞式声源是目前两种相对较为成熟的低频发声方式,而这两种发声方式又各产生了炸药动力和压缩空气动力两类设备。通过对两种发声原理和声场指标的对比分析,可以看出两种发声方式的优缺点和发展趋势,有助于次声源技术的进一步发展。
As the core technology of infrasound technology, the development of infrasound determines the overall process of infrasound technology. Tube sound source and piston sound source is the current two relatively mature low-frequency sound way, and these two sound modes have each produced explosive power and compressed air power two types of equipment. By comparing and analyzing the two sounding principles and sound field indexes, the advantages, disadvantages and development trends of the two sounding modes can be seen, contributing to the further development of the second sound source technology.
