Abstract
The Technical Memorandum reviews the literature since 1962 on underwater ambient noise. Particular attention is paid to those factors which influence noise levels and directionality in shallow water. Infrasonic noise, seismic noise in the sea bed, ship generated noise, and wind generated noise are considered. Noises of biological origin are acknowledged but not described in detail. The importance of understanding sound propagation phenomena, including bottom interaction, and of modelling is discussed. Suggestions for future research on shallow water noise are offered. The document does not consitute a summary of results, but rather is an account of work done and principles applied.
