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 ...
Swedish soldiers operating an acoustic locator in 1940. Acoustic location is a method of determining the position of an object or sound source by using sound waves. Location can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the earth).
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.
3D sound localization refers to an acoustic technology that is used to locate the source of a sound in a three-dimensional space.The source location is usually determined by the direction of the incoming sound waves (horizontal and vertical angles) and the distance between the source and sensors.
While the relationship between human perception of sound and various attributes of the sound field is not yet well understood, [2] DSP algorithms for sound localization are able to employ several mechanisms found in neural systems, including the interaural time difference (ITD, the difference in arrival time of a sound between two locations), the interaural intensity difference (IID, the ...
The technique enhances the perception of sound spatialization by exploiting sound localization: a listener's ability to identify the location or origin of a detected sound in direction and distance. This is achieved by using multiple discrete audio channels routed to an array of loudspeakers . [ 1 ]
This fade over was overlaid by many wall reflections from the sound situation before. Obviously no sound source localization was possible during this phase. At the end, when only loudspeaker 2 emitted sound, the situation was quite similar, the sound of the wall reflections, which arrived simultaneously, prevented a localization of this sound ...
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.
