IMPROVEMENT OF ACOUSTIC FEATURES OF CATALYTIC MUFFLERS
This article describes an experimental method of designing mufflers based of finite element modelling and the results of
experimental study. We have presented the results of studies, including in the form of sound pressure distribution over the internal
volume and transmission losses of the developed designs of the muffler. Based on the results of these studies, a design with the best vibroacoustic
features was selected. The results of experimental testing of the developed and manufactured design of a catalytic silencer
in a car are presented.
