Abstract:

The subject Underwater Sound covers phenomena as complex and diverse as the imagination and patience of the investigator will allow. An important part of the subject deals with the sonar parameters, in the form of loss or strength coefficients. During the twenty years that appreciable effort has been expended in experimentation and analysis, the great emphasis has been in two areas a Quantitative investigation of the sonar parameters b Quantitative investigation of the ocean environment. Knowledge of the environment has been applied to the estimation of the parameters, and to the description of other aspects of underwater sound.
