Summary:The method of selecting the configuration of dissipative mufflers with the required acoustic efficiency is considered. A specific feature of the approach is the use of an integral indicator of acoustic efficiency and dimensionless geometric parameters. The studies were carried out using finite element calculations. In the finite element model of dissipative mufflers, the acoustic characteristics of a fibrous sound-absorbing material obtained from experimental studies were used .
