Shock tube technique for testing acoustic materials at very high sound amplitudes
Abstract
A new technique to test acoustic materials at very high sound levels is presented. This technique is based on the use of a shock tube, and was applied to acoustic samples having a facing made of perforated plates of different open area ratios. Results of the absorption coefficient at resonance for several values of the open area ratio are presented.
