CALCULATED UNDERWATER PRESSURE LEVELS FROM SONIC BOOMS.

Abstract

The underwater pressure levels have been computed for two 'typical' sonic booms with amplitudes of 2.5 psf. The booms have periods of 0.1 and 0.3 sec and ground speeds of 1,500 and 2,500 ft/sec, respectively. The computed levels are compared with ambient levels from various sources. It would appear that at frequencies to which the acoustic receptors of underwater animals are most sensitive, there are often acoustic signals in the ocean that equal or exceed the signals due to sonic booms falling on the surface of the ocean.
