Report on Underwater Sound Pressures Beneath a Ship-Mounted Source as a Function of Bottom Impedance

Abstract

The sound pressure distribution directly beneath a ship-mounted source has been investigated, and over 200 experimental records have been made, in summer and in winter, at various frequencies from 36 cps to 2000 cps, and at various locations in the Potomac River area. The technique and the analysis are of general applicability and most of the findings are believed to be typical.
