| 摘 要： | W.Neise和G.H.Koopman首次采用了共鸣器对风机进行降噪，这种方法不影响，风机的空气动力性能。但是共鸣器的长度、口部穿孔率及孔径等参数还没有普遍规律可循，只能通过试验加经确定，本文将共鸣器与微穿孔板吸声理论结合起来，以9－28－I4A离心通风机为试验机，对共鸣器及其参数进行进一步研究。

| Abstract: | W. Neise and G. H. Koopman were the first to employ the acoustic resonators for reducing the ventilator noise. The method does not affect the aerodynamic performance of the ventilator ,but the resonator parameters such as the length,the perforating rate at the mouth,and the aperture could only be determined by test. In this investigation, taking the 9 - 28 - IA type centrifugal ventilator as the testing machine,the parameters of the acoustic resonator are further studied by combining with the noise absorbing theory of microbore plates. |
