The sounds of which frequency are human beings most sensitive

A. 400 hertz
B. 20 hertz
C. 20000 hertz
D. 5000 hertz

Check Answer

The correct answer is C) 20,000 hertz.

The sounds of frequencies between 20 Hz and 20,000 Hz (20 kHz) are generally audible to human beings, but our sensitivity to different frequencies varies. Human beings are most sensitive to sounds in the range of 2,000 Hz to 5,000 Hz, which is in the middle of the audible frequency range. However, we can still hear sounds at much higher frequencies, up to around 20,000 Hz, although our sensitivity to these higher frequencies decreases as we age.
