Sound Source Localization

2010
Automatic sound source localization has recently gained interest due to its various applications that range from surveillance to hearing aids, and teleconferencing to human computer interaction. Automatic sound source localization may refer to the process of determining only the direction of a sound source, which is known as the direction-of-arrival ...

Influence of sound source width on human sound localization

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
Free-field sound localization experiments generally assume that a loudspeaker can be approximated by a point-source; however, a large loudspeaker may extend beyond the width that two sources can be discriminated. Humans can accurately discriminate sound source locations within a few degrees, thus one might expect localization precision to decrease as a

Sound localization on a horizontal surface: virtual and real sound source localization

Virtual Reality, 2015
As the technology improves and their cost decreases, tabletop computers and their inherent ability to promote collaboration amongst users are gaining in popularity. Their use in virtual reality-based applications including virtual training environments and gaming where multi-user interactions are common is poised to grow.

Probabilistic sound source localization

2007 International Conference on Control, Automation and Systems, 2007
Sound localization is one of ways that keep the relation with robot. Time delay of arrival (TDOA) between two microphones through cross-correlation method has been used for sound localization in our robot platforms. However, since cross-correlation values are highly dependent on the upcoming sound signal and acoustic environment, time delay values and ...

Dynamic theory of sound-source localization

The Journal of the Acoustical Society of America, 1974
Under idealizations about the nature of the path taken by sounds to each of a listener's two ears, and the shape of the listener's head, it is shown that both the azimuth and the range of a sound source can be expressed in terms of the rate at which certain sound stimulus parameters change when sound-source azimuth varies.

Sound source localization by fishes

Journal of the Acoustical Society of America, 2016
The ability to locate sound sources enables animals to detect prey, avoid predators, and communicate with conspecifics, and is thus basic to the survival of many vertebrate species. Evidence suggests that the capacity to locate sound sources is common to amphibians, reptiles, birds, and mammals, but surprisingly it is not known whether fish locate ...

The Role of Phase Changes in Sound Signals in Localization of Sound Sources

Neuroscience and Behavioral Physiology, 2004
The auditory system in humans and animals makes virtually no discrimination of phase changes in the structure of monaurally presented sound signals. However, electrophysiological studies have demonstrated marked changes in the responses of the central parts of the auditory system when the phase structure of the signal changes during presentation of the

Role of spectral detail in sound-source localization

Nature, 1998
Sounds heard over headphones are typically perceived inside the head (internalized), unlike real sound sources which are perceived outside the head (externalized). If the acoustical waveforms from a real sound source are reproduced precisely using headphones, auditory images are appropriately externalized and localized. The filtering (relative boosting,

Cohesive Particle Filtering for Sound Source Localization

2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006
We present a novel resampling technique for particle filtering algorithms based on a model of attractive and repulsive forces. The new approach avoids the common degeneracy problem found in traditional resampling algorithms that prevents precise tracking of a source.
