摘　　要：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 the infrasound technology research,the development of the infrasonic sound source determines the overall process of infrasound technology.Tubular sound source and piston acoustic source are two kinds of relatively mature way of infrasonic sound production,which produce the explosive power equipment and the compressed-air power equipment separately.It can be shown that the advantages and disadvantages of two ways of sound production and the development of the two ways,which can contribute to the further development of the infrasonic sound source technology by analyzing the comparison between two kinds of vocalism principles and the sound field indicators.
