摘要
运用史蒂文斯稳态宽频带噪声响度计算方法以及Fastl总感觉噪度计算方法,分别对压缩机改进前、加装小孔消声器后左侧和后端面的噪声进行了声品质评价分析;分析表明,安装小孔消声器后,在噪声降低的同时,压缩机左侧和后端面的响度分别下降了10.25、13.3 sone,下降率均达到了40%以上,总感觉噪度分别下降了12.5、15 noy,下降率均达到了45%以上,说明小孔消声器对压缩机的声品质改善是非常理想的。
By of Stevens steady wide frequency noise loudness and Fastl total sensation noise calculation method, sound quality evaluation of the noise left and back-end face was studied before the compressor improved and after the minipore muffler installed. The research indicates that the compressor noise is reduced, at the same time, the loudness left the compressor and the back - end face is reduced by 10.25 sone and 13.3 sone respectively. The rate reduced is over 40%. The total sensation noise is reduced by 12.5 noy and 15 noy, the rate achieved is over 45%. It is very perfect to improve the compressor sound quality with the use of minipore muffler.
