Motion strategies for binaural localisation of speech sources in azimuth and distance by artificial listeners
Localisation in azimuth and distance of sound sources such as speech is an important ability for both human and artificial listeners. While progress has been made, particularly for azimuth estimation, most work has been directed at the special case of static listeners and static sound sources. Although dynamic sound sources create their own localisation challenges such as motion blur, moving li...
متن کاملSound localization under perturbed binaural hearing.
This paper reports on the acute effects of a monaural plug on directional hearing in the horizontal (azimuth) and vertical (elevation) planes of human listeners. Sound localization behavior was tested with rapid head-orienting responses toward brief high-pass filtered (>3 kHz; HP) and broadband (0.5-20 kHz; BB) noises, with sound levels between 30 and 60 dB, A-weighted (dBA). To deny listeners ...

متن کاملPrediction of Perceived Elevation Using Multiple Pseudo-binaural Microphones
Computational auditory models that predict the perceived location of sound sources in terms of azimuth are already available, yet little has been done to predict perceived elevation. Interaural time and level differences, the primary cues in horizontal localisation, do not resolve source elevation, resulting in the ‘Cone of Confusion’. In natural listening, listeners can make head movements to ...
متن کاملContribution of Head Shadow and Pinna Cues to Chronic Monaural Sound Localization
Monaurally deaf people lack the binaural acoustic difference cues in sound level and timing that are needed to encode sound location in the horizontal plane (azimuth). It has been proposed that these people therefore rely on spectral pinna cues of their normal ear to localize sounds. However, the acoustic head-shadow effect (HSE) might also serve as an azimuth cue, despite its ambiguity when ab...
