The audibility curve shows that auditory threshold is minimal for
A)frequencies between about 20 to 60 Hz.
B)frequencies above 10,000 Hz.
C)frequencies between about 500 to 5,000 Hz.

Question

Quizplus · Accepted Answer

The audibility curve shows that the auditory threshold is minimal for frequencies between about 500 to 5,000 Hz. This means that our ears are most sensitive to sounds within this frequency range, which is why this range is often emphasized in music and speech. Frequencies below 500 Hz and above 5,000 Hz require greater amplitude or volume to be perceived as equally loud as sounds within the 500 to 5,000 Hz range. Frequencies below about 20 Hz and above about 20,000 Hz are generally inaudible to most humans. Therefore, choice A and B are incorrect.
