Sound Analysis of the U.S.S. S-20

Abstract

An immediate problem was to determine whether the sound insulation of certain auxiliaries on the S- 20 had any material effect on the range at which she could be hoard by another ship listening to the sound through the water. The general problem was to measure the intensity of the sound in water produced by the S- 20 under different operating conditions at different speeds, ranges, and depths; to compare the relative intensity of the sounds produced by each of the driving units; and, if possible, to determine the mechanism of the production of sound in water by a ship underway.
