Abstract:

The U.S. Army Aeromedical Research Laboratory USAARL Auditory Protection and Performance Division APPD owns, operates, and maintains a 6-inch inner diameter shock tube to create shock waves in a controlled environment. Firing parameters such as diaphragm material, diaphragm thickness, and transducer location can alter the properties of the produced shock wave. The measured shock wave properties in this study are peak level and A-duration. The shock tube produced more consistent peak levels and A-durations as cylinder pressure approached the natural membrane burst pressure or 80 psi limit. With enough space in the exposure room, the 6-inch shock tube satisfies the requirements in American National Standards InstituteAcoustical Society of America ANSIASA standard S12.42-2010 for impulse peak insertion loss value IPIL calculations.
