Sound Research and Development with Particular Reference to Tests on the U.S.S. Semmes on July 6-28, 1937

Abstract

The present report deals with two sound problems; first, "Sound Research and Improvement," and second, "Reduction of Sound Generated by Naval Vessels." Under the first it describes the progress made in echo detection equipment during the past three years and under the second, it covers briefly the sound analysis work done on the S-20, the SEMMES, and on propeller models and discusses certain deductions therefrom as to the sources of the underwater sound generated by Naval vessels and their contribution to the general background of noise picked up by the echo detection apparatus.
