Modelling of human low frequency sound localization acuity demonstrates dominance of spatial variation of interaural time difference and suggests uniform just-noticeable differences in interaural time difference. [PDF]
PLoS ONE, 2014 Sound source localization is critical to animal survival and for identification of auditory objects. We investigated the acuity with which humans localize low frequency, pure tone sounds using timing differences between the ears.

Cellular Strategies for Frequency-Dependent Computation of Interaural Time Difference [PDF]
Frontiers in Synaptic Neuroscience, 2022 Binaural coincidence detection is the initial step in encoding interaural time differences (ITDs) for sound-source localization. In birds, neurons in the nucleus laminaris (NL) play a central role in this process.

Microsecond interaural time difference discrimination restored by cochlear implants after neonatal deafness [PDF]
eLife, 2021 Spatial hearing in cochlear implant (CI) patients remains a major challenge, with many early deaf users reported to have no measurable sensitivity to interaural time differences (ITDs).

The Relationship Between Interaural Insertion-Depth Differences, Scalar Location, and Interaural Time-Difference Processing in Adult Bilateral Cochlear-Implant Listeners [PDF]
Trends in Hearing, 2022 Sensitivity to interaural time differences (ITDs) in acoustic hearing involves comparison of interaurally frequency-matched inputs. Bilateral cochlear-implant arrays are, however, only approximately aligned in angular insertion depth and scalar location ...

Effects of Hearing Loss on Interaural Time Difference Sensitivity at Low and High Frequencies [PDF]
Trends in Hearing, 2022 While many studies have reported a loss of sensitivity to interaural time differences (ITDs) carried in the fine structure of low-frequency signals for listeners with hearing loss, relatively few data are available on the perception of ITDs carried in ...

Effect of inter-aural modulation depth difference on interaural time difference thresholds for speech: An observational study [version 1; peer review: 2 approved] [PDF]
F1000Research, 2020 Background: The temporal envelope (ENV) plays a vital role in conveying inter-aural time difference (ITD) in many clinical populations. However, the presence of background noise and electronic features, such as compression, reduces the modulation depth ...

Rate dependent neural responses of interaural-time-difference cues in fine-structure and envelope [PDF]
PeerJAdvancements in cochlear implants (CIs) have led to a significant increase in bilateral CI users, especially among children. Yet, most bilateral CI users do not fully achieve the intended binaural benefit due to potential limitations in signal processing

Interaural-time-difference thresholds for broad band-limited pulses are affected by relative bandwidth not temporal envelope sharpness [PDF]
JASA Express Letters, 2021 Humans are sensitive to interaural time differences (ITDs) conveyed by slow modulations on high-frequency carrier signals. Sensitivity appears to be affected by temporal envelope sharpness, but it is unclear if there is a limit to which sharpness affects

Interaural time difference sensitivity under binaural cochlear implant stimulation persists at high pulse rates up to 900 pps [PDF]
Scientific Reports, 2023 Spatial hearing remains one of the major challenges for bilateral cochlear implant (biCI) users, and early deaf patients in particular are often completely insensitive to interaural time differences (ITDs) delivered through biCIs.

Across-frequency combination of interaural time difference in bilateral cochlear implant listeners [PDF]
Frontiers in Systems Neuroscience, 2014 The current study examined how cochlear implant (CI) listeners combine temporally interleaved envelope-ITD information across two sites of stimulation.
