摘要
为了定位设备噪声源,用声强测量方法测量了汽轮鼓风机和射流抽汽器的声强。采用声功率排序法对所测设备的噪声源进行了排序。结果表明:汽轮鼓风机是主要噪声源,鼓风机部分是汽轮鼓风机的主要噪声源。声强测量方法是多声源噪声系统中定位设备噪声源的有效方法。
In order to localize noise source of equipments,sound intensity of turbine-blowing machine and Jet flow vapor extractor has been measured.Noise sources were ranged according to sound power.Results show turbine-blowing machine is major noise source;blowing machine is major noise source of turbine-blowing machine.Sound intensity measurement is effective method for localization noise source in multi-source noise system.
