High-Intensity Sound in Air Saturated, Fibrous Bulk Porous Materials.

Abstract

An investigation of the interaction of high-intensity sound with bulk porous materials is reported. The work is mainly experimental but some theoretical results are obtained. Previous studies of high-intensity sound in porous materials have been limited to porous sheets. Most tests in the present study were done on Kevlar 29, a fibrous plastic material, for the porosity range between 0.985 and 0.809. The nonlinear behavior of the materials was first described by dc flow resistivity tests. Then acoustic propagation and reflection were measured. (Author)
