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 ...
Acoustic wayfinding, the practice of using auditory cues and sound markers to navigate indoor and outdoor spaces; Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of ...
Sound localization technology is used in some audio and acoustics fields, such as hearing aids, surveillance [1] and navigation.Existing real-time passive sound localization systems are mainly based on the time-difference-of-arrival approach, limiting sound localization to two-dimensional space, and are not practical in noisy conditions.
Perceptual-based sound localization may be used to enhance and supplement robotic navigation and environment recognition capability. [1] In addition, it is also used to create virtual auditory spaces which is widely implemented in hearing aids.
An application of 3D sound synthesis is the sense of presence in a virtual environment, by producing more realistic environments and sensations in games, teleconferencing systems, and tele-ensemble systems. 3D sound can also be used to help those with sensory impairments, such as the visually impaired, and act as a substitute for other sensory feedback.
3D sound reconstruction is the application of reconstruction techniques to 3D sound localization technology. These methods of reconstructing three- dimensional sound are used to recreate sounds to match natural environments and provide spatial cues of the sound source.
Some are confined to refugee camps in adjoining countries like Chad. Many others are bottled up at Port Sudan, the Red Sea city from which the central government operates, since Khartoum remains a ...
By taking a holistic process, where a stream (of feature-based sounds) correspond to neuronal activity distributed in many brain areas, the perception of the sound could be mapped and modeled. Two different solutions have been proposed to the binding of the audio perception and the area in the brain.
