摘要：
The article is devoted to the issues of designing modern energy-efficient silencers of gas-air paths. Various types of silencers used to reduce the noise of smoke exhausters and blow fans are considered. Possible solutions for reducing the resistance of silencers are given. Aerodynamic modelling of the plate silencer was performed in order to determine the optimal shape of the front and end fairings. It is shown that the application of the set of measures allows minimizing the aerodynamic drag of the silencer, and in some cases-to improve the aerodynamic characteristics of gas-air ducts.
