Question

Why can't you use ITD for high frequencies?

a) ITD is not reliable for any frequencies
b) High frequencies have different waveforms
c) ITD is too complex to calculate for high frequencies
d) High frequencies arrive simultaneously at both ears

Answer 1

High frequencies arrive simultaneously at both ears, making it ineffective to use Interaural Time Difference (ITD).

Step-by-step explanation:

The answer is d) High frequencies arrive simultaneously at both ears.

When a sound wave with a high frequency reaches the ear, it causes the eardrum to vibrate rapidly. These high-frequency vibrations can reach both ears at the same time because they travel through the air quickly. Since the Interaural Time Difference (ITD) relies on a time delay between when sound arrives at each ear to determine the direction of the sound source, it is not effective for high frequencies since they arrive at both ears simultaneously.
