Bats that echolocate have a range of frequencies for different purposes and techniques for preventing themselves from becoming deafened by their own sounds. Some prey have evolved ways of detecting when bats are emitting high frequencies in their direction, and some fish have adapted to detect the sounds dolphins use to find them.
