Abstract:

A semi-empirical formula TL 15 log R A Blog f Clog f sq R D in dB is proposed to express sound transmission loss in shallow water as a function of range and frequency. The four coefficients A, B, C and D are determined from either experimental or model data by the use of a least-squares surface fit and the formula usually gives a standard derivation of the order of a few dB. The formula can be used for studying system performances, sonar range predictions, and as a compact data storage. Author
