Abstract
Interaural time and level differences (ITDs and ILDs) contribute to the localization of sound sources; however, reverberation or use of cochlear implants diminishes the role of ITDs. Intracranial lateralization was investigated in normal-hearing listeners using correlated or uncorrelated narrowband noises, where ITDs and/or ILDs from a typical headrelated transfer function were applied. Results showed that ITDs and ILDs contributed to lateralization for correlated noises. ILDs contributed to lateralization for uncorrelated noises. Frequency-dependent ITD and ILD weighting occurred. These data help understand the across-channel processing of ITDs and ILDs, particularly when ITDs may not be available to the listener.
Highlights
Complex sounds are localized in the horizontal plane by processing interaural time differences (ITDs) and interaural level differences (ILDs)

To investigate across-channel ITD and ILD processing, we presented narrowband noises to normal hearing listeners over headphones where the ITDs and ILDs were derived from headrelated transfer functions (HRTFs)
Summary
Complex sounds are localized in the horizontal plane by processing interaural time differences (ITDs) and interaural level differences (ILDs). Listeners with normal acoustic hearing demonstrate a low-frequency (
