Analysis of compressor muffler using transmissibility
전달률을 이용한 압축기용 소음기 해석
Abstract
The common practice to reduce the compressor noise is installing a muffler. The noise reduction performance of the muffler is the most critical one for the total noise characteristics of the compressor. In this paper, a simple impedance approach using the concept of transmissibility is employed for the acoustic analysis of the muffler, It is known that transmissibility is directly related to insertion loss, and thus transmissibility can Indicate the correct performance of the muffler. The analysis result is supported by a Finite Element Model. In addition, some experiments conducted also show that the transmissibility is mildly related to the measured sound pressure outside the compressor.
