Sonic booms laid down by Navy fighter aircraft flying at Mach 1.1-1.2 have been observed below the surface of the sea by means of a string of hydrophones 195 feet long dangling from a surface ship. The underwater booms were found to decay about as the -3/2 power of the depth below the surface, to have the same spectral content as the boom in air, and to travel down the string with the velocity of sound in water. These findings contradict the theory of an 'inhomogeneous' wave incident beyond the critical angle, as originally stated by Rayleigh and as recently extended to sonic booms by Sawyers and Cook. They suggest, instead, that the underwater sonic boom is a wave scattered by the rough sea surface into the sea below. Its decay with depth is so rapid that it is not likely to be perceptible against the ambient noise background at depths greater than one or two thousand feet in the deep sea. (Author).

Download Determination of Aircraft Sonic Boom Noise Penetration Into Seas, Bays, and Lakes for Environmental Assessment Book in PDF, Epub and Kindle
Sonic boom noise from overwater supersonic aircraft operations penetrates into the water. The present work developed an algorithm to simulate this penetrating sonic boom noise for realistically shaped sonic booms, predictions previously unavailable. The new algorithm assumes that the water surface is fairly flat and that the water is deep enough so that bottom reflections can be ignored. The algorithm was used to model the underwater sonic boom noise for the cases of incident sonic boom waves distorted by atmospheric effects and by common aircraft maneuvers. It was found that certain aircraft maneuvers and atmospheric effects can increase the penetration of the sonic boom noise, while others decrease it.
