Finite element calculation and analysis of acoustic attenuation performance of perforated tube silencers 穿孔管消声器消声性能的有限元计算及分析
3.
Comparisons between the acoustic performances of the air cleaners with and without filter paper illustrated that the acoustic attenuation performance has been improved due to the existence of filter paper 通过比较不带滤纸和带有滤纸的空气滤清器的声学性能结果表明,滤纸的考虑与否对空滤器的中高频消声性能有很大影响。
