Abstract

A kind of hybrid method to calculate the sound transmission loss (STL) of the air cleaner is researched here and the acoustical effect of the filter material is emphasized. The two-port model is decided to describe the sound transmission property of the filter material and the experimental identification method to obtain the elements of the transfer matrix is researched as well. This calculation method is applied to calculate the STL of a kind of engine air cleaner in two conditions with and without the acoustical effect of the filter material. The filter material shows the effect of sound absorption and acoustical damping and raises the level of the STL.
