摘要
通过用Labiew软件测试系统对电吹风进行噪声测试,并对噪声进行频谱分析,分析得出电吹风的主要噪声源并提出改进的一些方法。
By Labview software, the acoustic test of electric hair dryer is conducted. Its main noise source includes fan noise, the mechanical noise generated by micro electric engine, and the eddy-noise due to the tube resistance. In this article some improved methods are proposed.
