Ecology and Echolocation of Bats and Toothed Whales

... Echolocation in bats is used for orientation, navigation and recognition of prey. Sonar pulses are produced in microchiropteran species by the larynx and emitted through the nose, which can be highly evolved to focus sonar pulses, or the mouth. Returning echoes are received in the ears, and pinna ca ...

Sound localization

Sound localization refers to a listener's ability to identify the location or origin of a detected sound in direction and distance. It may also refer to the methods in acoustical engineering to simulate the placement of an auditory cue in a virtual 3D space (see binaural recording, wave field synthesis).The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time- and level-differences between both ears, spectral information, timing analysis, correlation analysis, and pattern matching.These cues are also used by other animals, but there may be differences in usage, and there are also localization cues which are absent in the human auditory system, such as the effects of ear movements. Animals with the ability to localize sound have a clear evolutionary advantage.
