WebSharks have the ability to determine the direction of a given scent based on the timing of scent detection in each nostril. This is similar to the method mammals use to determine the direction of sound. They are more attracted to the chemicals found in the intestines of many species, and as a result often linger near or in sewage outfalls. WebDec 29, 2011 · Get 6 directional microphones and point them up, down, front, back, left, and right. By looking at the relative amplitudes of the mic signals in response to a sound, you could pretty easily determine which direction a particular sound is coming from. Increase the number of microphones for increased resolution.

WebMay 5, 2024 · Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied.
