Question

Quizplus · Accepted Answer

ILD (interaural level difference) and ITD (interaural time difference) are both affected by the location of the sound source relative to the listener's head. When a sound is directly in front or behind the listener, there is no difference in ILD or ITD. However, when the listener moves their head, the differences in ILD and ITD allow the listener to localize the sound source. Therefore, the only way to differentiate between a sound source in front or behind the listener is to move the head.
