Question 2

Correct Answer:

Verified

Low-frequency sounds easily diffract around a listener's head. These sounds are clearly heard by both ears, regardless of their source. As a result, the amplitude of low-frequency sounds is virtually identical for each ear, making the interaural-level difference an ineffective source of azimuth information. However, it will still take additional time for a sound originating from a listener's side to reach the more distant ear, making the interaural time difference effective in discerning azimuth.

Azimuth refers to the _____ dimension.
