Abstract

The sound absorption coefficient and transmission loss of different sound absorbing fabrics are measured and it is shown that the fabric may be modeled using the well-known equations for microperforated panels. It is shown that the normal incident sound absorption can be measured with a given depth, and then an effective perforation diameter and porosity can be determined via a least squares curve fit. The effective parameters can then be used to predict the sound absorptive performance for different cavity depths as well as the transmission loss through a single layer and two layers of fabric.
