Interaural Differences in Time and Level?

In humans, horizontal sound localization mainly relies on interaural differences in sound arrival time and sound level. ... These results suggest that the auditory cortex contains an integrated code of sound laterality, but also retains independent information about ITD and ILD cues.

What are Interaural level differences?

The interaural level difference is the difference in loudness and frequency distribution between the two ears. ... We can define the acoustic shadow as the area on the side of the head opposite from the source of a sound in which the loudness of a sound is less because of blocked sound waves.

How Interaural time differences and interaural level differences help us locate sound sources?

The interaural time difference (or ITD) when concerning humans or animals, is the difference in arrival time of a sound between two ears. ... This pathlength difference results in a time difference between the sound's arrivals at the ears, which is detected and aids the process of identifying the direction of sound source.
