Noise reduction of coincidence detector output by the inferior colliculus of the barn owl [PDF]
, 2006 A recurring theme in theoretical work is that integration over populations of similarly tuned neurons can reduce neural noise. However, there are relatively few demonstrations of an explicit noise reduction mechanism in a neural network.

Development of Binaural Sensitivity: Eye Gaze as a Measure of Real-time Processing
Frontiers in Systems Neuroscience, 2020 Children localize sounds using binaural cues when navigating everyday auditory environments. While sensitivity to binaural cues reaches maturity by 8–10 years of age, large individual variability has been observed in the just-noticeable-difference (JND ...

Cues for Directional Hearing in the Fly Ormia ochracea
Frontiers in Ecology and Evolution, 2021 Insects are often small relative to the wavelengths of sounds they need to localize, which presents a fundamental biophysical problem. Understanding novel solutions to this limitation can provide insights for biomimetic technologies. Such an approach has

PLoS Biology, 2010 Low-frequency sound localization depends on the neural computation of interaural time differences (ITD) and relies on neurons in the auditory brain stem that integrate synaptic inputs delivered by the ipsi- and contralateral auditory pathways that start ...

Interaural Time and Intensity Difference and the MLD [PDF]
The Journal of the Acoustical Society of America, 1965 Masking-level differences (MLD) for a 600-cps low-pass transient were explored as a function of (1) interaural time difference (Δt; (2) interaural intensity difference (ΔI); and (3) combinations of Δt and ΔI. Masking-level difference here is the difference between two levels of coherent noise (N0), one required to mask a given condition of click, the ...

Interaural Coherence Estimation for Speech Processing in Reverberant Environment
Applied Sciences, 2020 Interaural coherence is used to quantify the effects of reverberation on speech, and previous studies applied the conventional method using all previous time data in the form of an infinite impulse response filter to estimate interaural coherence.

Spectral integration of interaural time differences in auditory localization [PDF]
Proceedings of Meetings on Acoustics, 2013 This study investigates how the auditory system integrates spatial information across frequency. In experiment 1, discrimination thresholds for interaural time differences (ITDs) were measured as a function of both reference ITD and center frequency (CF) of noises with bandwidth of one ERB. In addition, discrimination thresholds were also measured as a

Temporal Map Formation in the Barn Owl’s Brain [PDF]
, 2001 Barn owls provide an experimentally well-specified example of a temporal map, a neuronal representation of the outside world in the brain by means of time. Their laminar nucleus exhibits a place code of interaural time differences, a cue which is used to

The Anatomical Record, EarlyView.Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
