Evidence for a neural source of the precedence effect in sound localization.
Normal-hearing human listeners and a variety of studied animal species localize sound sources accurately in reverberant environments by responding to the directional cues carried by the first-arriving sound rather than spurious cues carried by later-arriving reflections, which are not perceived discretely. This phenomenon is known as the precedence effect (PE) in sound localization. Despite dec...

Dooling The precedence effect has previously been found in mammals, anurans, invertebrates, and one species of bird, the barn owl. Here, the precedence effect was measured in a small parrot, the budgerigar (Melopsit...
متن کاملModeling the precedence effect for binaural sound source localization in noisy and echoic environments
We present a new way of modelling the Precedence Effect to enable the robust measurement of localization cues (ITD and IID) in echoic environments. Based on this we developed a localization system which is inspired by the auditory system of mammals. It uses a Gammatone filter bank for preprocessing and extracts the ITD cue via zero crossings (IID calculation is straight forward). The mapping be...
متن کاملSound localization precision under conditions of the precedence effect: effects of azimuth and standard stimuli.
Minimum audible angles (MAAs) were estimated for single noise bursts, and for burst pairs that satisfied the conditions of the precedence effect (that is, produced fused images). In one burst-pair condition, the bursts to be discriminated differed in lead location; in the other, they differed in lag location. Sounds were presented over loudspeakers. MAAs were lowest for single bursts, slightly ...
متن کاملDifference in precedence effect between children and adults signifies development of sound localization abilities in complex listening tasks.
The precedence effect refers to the fact that humans are able to localize sound in reverberant environments, because the auditory system assigns greater weight to the direct sound (lead) than the later-arriving sound (lag). In this study, absolute sound localization was studied for single source stimuli and for dual source lead-lag stimuli in 4-5 year old children and adults. Lead-lag delays ra...
