Intensity Probe 02-20 Using Miniature Hollow Spheres
Abstract
A probe is designed to measure the acoustic intensity at the primary frequencies (20-30 kHz) of a parametric array. It is designed to operate at depths up to 61 m with a pressure sensitivity of less than -235dB re 1V/mPa while not disturbing the acoustic field of interest. Higher sensitivity would result in saturation when exposed to the expected sound pressure levels. The sensitivity and depth requirements were met, while the acoustic field disturbance issue is not yet fully resolved.
