Underwater Sound and Naval Acoustical Research and Applications before 1939

Abstract

This report describes some of the highlights of underwater sound and other naval acoustical technology in the United States during the period of World War I to World War II. A number of accomplishments in subaqueous acoustics of the Naval Research Laboratory are given, emphasizing sonar equipment research and development. Acoustic studies in air and ocean environments carried out at NRL are also described; and a general glimpse of the research climate in the early decades of NRL is portrayed.
