摘要

本文对以涡声相互作用为基础的通气的多孔板共振腔结构的声学性质进行了一些实验研究和分析。着重于声衬的孔径、腔深、孔板厚度对声衬性能的影响。对实验的结果进行了一些分析，给出了厚板通气声衬声抗的一种算法。对吹气与吸气情况下声衬的性质进行了对比。

Abstract

An experimental investigation has been carried out on a kind of perforated liner with a bias flow through the apertures

according to Howe’s vortex sound theory.The attention was focused on the effects of the aperture size

the cavity depth and the perforated plate thickness on the impedance of the liner.The algorithm of the reactance is modified for the liner with thick perforated plate

based on the analysis of experimental results.The perforated liners with sucking and blowing bias flow are compared and the same conclusions are drawn out.
