From the viewpoint of fluid dynamics analysis, whistle in essence belongs to a kind of hydrodynamic acoustic generator Fluid power type generator according to the fluid types can be divided into three basic types: (1) the gas flow, using gas as a power source, such as Hartmann whistle (Hartmann whistle), spiral flute, etc., including Hartmaim whistle is J.H artm improved a resonant cavity whistle, can generate high sound intensity at a reasonable efficiency. (2) the fluid flow, the use of fluid as power source, such as reed whistle, it is by the R.P ohlman and W.J anovsky invention, also called Pohlmann - Janovsky whistle. (3) gas liquid type, the use of high gas or liquid to produce sound and ultrasonic, such as spiral whistle and circular plate whistle. Fluid power type sound whistle is a hot research object for acoustic researchers both at home and abroad, especially in pneumatic acoustic need is high sound pressure level and frequency band is wide voice, and most of the sound source追问这个是机器翻译吗？追答不完全是这个是我们老师也帮着翻译过的追问最后有几句话看不太懂，能修改下吗？从especially in pneumatic……到结尾。其他的都没什么大问题改完这一点就直接采纳了，我也是有时间限制。。追答哦 从especially in pneumatic……不是答案翻译过来的意思是如上所述，，，，，，辐射特性追问嗯？不是“尤其在气动声学中……流体动力式发生器”这句吗？而且后面有一段也没有翻译过来追答霍霍 看错了 不好意思我只能翻译到这里了 不好意思啊追问没事那这一句能修改下吗？结构有点不对吧追答哪里追问就是我说的这句从especially in pneumatic……到结尾这句话修改下
