Certain species of dolphins use echolocation to find their prey: they emit ticking sounds and then receive echoes reflected by distant objects in the water  Marine biologists speculate that these ticking sounds may have another effect: the dolphins use unusually high-frequency ticking
The sound waves emitted by the bat not only enable it to find its prey, but this sound wave can form a special stimulus to the prey, thereby helping the bat to capture them
 The sound overloads the prey's senses, which stuns prey at close range
