Abstract:

Material presented is a summary of present knowledge of aural recognition of underwater sounds. While the basic theory of the performance of the ear has been kept in mind, a deliberate attempt has been made to focus attention also on the many practical aspects of the information discussed. In part 1, the relevant facts on the structure and performance of the ear are presented. Part 2 analyzes the data on the masking of sounds produced by a distant target, while part 3 deals with the corresponding results for echoes.
