Do Signal Characteristics Determine a Bat’s Ability to Avoid Obstacles?
Bats of the suborder Microchiroptera navigate and hunt for prey chiefly by means of acoustic perception of the echoes of their own sonar signals. Echolocating bats emit species-specific sonar signals. In a compressive medium such as air, different sounds have different propagation, reflective and refractive properties. As such, different sounds, along with the different analyzing capacity of the auditory system, dictate the performance of bats in various hunting situations.
