Detect direction of sound

WebSound localization is the ability to tell the direction from which a sound is originating. When sound localization ability is low, it affects a person's safe interaction in an environment. Lack of sound localization ability can influence safe movement in public spaces. If a person cannot tell the direction of an approaching vehicle, with or ... 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.

WebFig. 1. Block diagram of vehicle counting and direction detection algorithm. The second microphone is chosen as a reference channel. In calculations far field assumption is applied. We assume that propagating sound waves are plane waves, neglecting curvaceous sound wave properties. Fig. 2. Vehicle sound arrival angle calculation model. WebWhen a sound comes from the left, the travel distance to your left ear is slightly shorter than the travel distance to your right ear. So the left hears it milliseconds before the right. This is your brain’s first clue that the sound might be coming from the left. But that information alone is not enough. It still needs more. The next clue is… 2.
