Design and Test of a Prototype Acoustic High-Intensity Infrasonic Test Chamber

Abstract

We describe the conception, design, mathematical modeling, construction, and test of a prototype acoustic test chamber intended to support the performance of high-intensity acoustic target-effects experiments on large targets at infrasonic frequencies. In initial experiments, the test chamber produced continuous sinusoidal sound pressure levels in excess of 140 dB over a frequency range of 5 to 20 Hz within a test volume of 5 m3.
