Abstract
A noise generator is created by having a high pressure gas applied to a Mach 2 nozzle which is combined in an adjustable nozzle assembly with a resonance tube of adjustable length with a closed end forming a Mach disk between them. The resultant compression and expansion shock wave oscillations exit the resonance tube and are propagated between reflecting domes which direct the generated noise around a test article in a housing which contains the generated noise. A muffler includes a water spray chamber and baffled bulkheads to dissipate the generated noise.
