Abstract
Diesel particulate filters are good tools in gas emission reduction (and also particulate matters) in addition to noise reduction. In this paper the effect of soot layer on both transmission losses and noise reduction factor is studied. It is clear that for both hot and cold conditions the transmission losses with the existence of soot layer are greater than those without soot layer existence, since the soot layer is considered here as a new medium or a new component that increases sound absorption and consequently increases the sound transmission losses.
