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. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...
In both humans and non-human primates, the auditory dorsal stream is responsible for sound localization, and is accordingly known as the auditory 'where' pathway. In humans, this pathway (especially in the left hemisphere) is also responsible for speech production, speech repetition, lip-reading, and phonological working memory and long-term ...
However, our localization acuity depends on whether the sound is located in front, to the side, behind, or above. Humans are very good at locating sounds in front of us, usually within 1 degree of ...
(sound source: 100 ms white noise from 90° azimuth, 0° elevation) The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. It is important in the localization of sounds, as it provides a cue to the direction or angle of the sound source from the head. If a signal ...
Both pathways project in humans to the inferior frontal gyrus. The most established role of the auditory dorsal stream in primates is sound localization. In humans, the auditory dorsal stream in the left hemisphere is also responsible for speech repetition and articulation, phonological long-term encoding of word names, and verbal working memory.
Human listeners combine information from two ears to localize and separate sound sources originating in different locations in a process called binaural hearing. The powerful signal processing methods found in the neural systems and brains of humans and other animals are flexible, environmentally adaptable, [ 1 ] and take place rapidly and ...
Human echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths.
The time, intensity, and spectral differences in the sounds arriving at the two ears are used in localization. Lateralization (localization in azimuth) of sounds is accomplished primarily by analyzing interaural time difference (ITD). Localization of high-frequency sounds is aided by analyzing interaural level difference (ILD) and spectral cues ...
