The noise of one aircompressor exceeded the noise standard in a workshops, and its cause is tested and analyzed in this paper. According to the analysis of the results of the test, a comprehensive scheme of noise control, including sound absorption, sound insulation, etc., is made. A mathematical model of aventilating fan cover is established, and the relevant parameters are determined. Then a set utility controlling approach is implemented. The consequence shows that this program not only gains good effects but also cater to state more technical criterion.%某空压机组噪声严重超标,对该车间内噪声超标的主要原因作了测试和分析.根据测试和分析的结果制定以吸声、隔声等噪声控制技术为主的综合治理方案.应用隔声理论和优化设计理论对隔声体进行了设计.并实施一套实用的控制措施.结果证明,此方案降噪效果明显,能完全满足企业提出的更高标准要求.
