Abstract:

Acoustic tests are performed on spacecraft and launch vehicle sub systems to qualify them for the acoustic environment that they encounter during flight. The importance of acoustic testing is described in this article.  Various methods of simulating the acoustic environment is highlighted.  Reverberant acoustic tests are generally performed on large sized test articles. The salient features of the reverberation chamber and its various components are presented.  The test procedures and required data analysis are detailed.
