Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that human directional hearing relies on head-related transfer functions and interaural time differences?

Yes. Multiple studies and computational models confirm that human directional and spatial hearing depends on binaural cues, including interaural time differences, and directional filtering via head-related transfer functions.

The analysis

The claim states that human directional hearing relies on head-related transfer functions (HRTFs) and interaural time differences (ITDs). The provided literature contains multiple direct sources (such as papers 4, 6, 7, and 9) confirming the critical role of HRTFs and binaural cues (ITDs/ITFs) in auditory localization and directional hearing. No retrieved papers contradict this standard auditory science principle.
