Front and back sound localization requires other mechanisms than ITD
Evidence
Note that there is no difference in the delay between front and back positions at the same angle. This means that we must use different mechanisms and strategies to differentiate between front and back sounds. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 717
