Shallow-water propagation of frequencies in aquatic insect sounds

Abstract

The possible use of sounds produced by aquatic insects over distances similar to those of terrestrial insects was examined. Pure tones, spanning the range of those found in aquatic insect sounds, were broadcast in shallow water. At intensities representative of those produced by aquatic insects, all frequencies were usually attentuated within 1 m and their function as acoustic beacons must be considered within such limits.
