Sea Floor Effects on Shallow-Water Acoustic Propagation
The acoustic propagation in the 24 Hz to 8 kHz band has been measured in a large number of coastal-water areas using explosive charges and digital techniques. When displaying the losses as a function of range and frequency a marked optimum frequency is observed in most of the cases. The acoustic characteristics of the sea floor over which the propagation measurements were made have been compared with the loss levels and the optimum frequencies and have shown, among other things, a relationship between the optimum frequency and sediment properties.
