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 ...
A general way to implement 3d sound localization is to use the HRTF(Head-related transfer function). First, compute HRTFs for the 3D sound localization, by formulating two equations; one represents the signal of a given sound source and the other indicates the signal output from the robot head microphones for the sound transferred from the source.
Acoustic source localization [4] is the task of locating a sound source given measurements of the sound field. The sound field can be described using physical quantities like sound pressure and particle velocity. By measuring these properties it is (indirectly) possible to obtain a source direction.
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.
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.
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.
[24] [25] The localization of a virtual source, based on level differences between two loudspeakers to the side of a listener, shows great inconsistency across the standardized 5.1 setup, also being largely affected by movement away from the reference position. 5.1 surround is therefore limited in its ability to convey 3D sound, making the ...
The central nucleus of the IC is a nearly obligatory relay in the ascending auditory system, and most likely acts to integrate information (specifically regarding sound source localization from the superior olivary complex [13] and dorsal cochlear nucleus) before sending it to the thalamus and cortex.
