Question

Why is the ITD irrelevant to high frequencies?

a) High frequencies have shorter wavelengths
b) High frequencies are absorbed by the head
c) ITD is always relevant
d) High frequencies travel at the same speed

Answer 1

High frequencies are not affected by the speed of sound, as sound waves travel at the same speed regardless of frequency. The speed of sound is determined by factors like temperature and humidity in the medium it travels through.

Step-by-step explanation:

One of the more important properties of sound is that its speed is nearly independent of frequency. This means that high frequencies are not absorbed or affected differently compared to low frequencies in terms of speed. The speed of sound in a medium is determined by factors like temperature, humidity, and density of the medium, rather than the frequency of the sound.

For example, if two individuals are standing at different distances from a sound source, they will both hear the sound at the same time, regardless of the frequency of the sound. This is because the speed of sound remains constant for all frequencies in a given medium.
