Abstract

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.

消声消声器的优化

本研究考虑了如何选择具有所需声学效率的消声消声器配置。该方法的一个特点是使用了声效积分指标和无量纲几何参数。研究是通过有限元计算进行的。在消声消声器的有限元模型中，使用了从实验研究中获得的纤维吸声材料的声学特性。
