Question

Is the human ear/brain more sensitive to a 500Hz signal or a 90000Hz signal?

A) 500Hz
B) 90000Hz
C) Both equally sensitive
D) Depends on individual preference

Answer 1

The human ear is more sensitive to a 500Hz signal than to a 90000Hz signal because the typical range of human hearing is between 20Hz and 20,000Hz.

Step-by-step explanation:

The human ear is more sensitive to a 500Hz signal than a 90000Hz signal. The range of human hearing is typically between 20Hz and 20,000Hz. Frequencies beyond 20,000Hz, commonly referred to as ultrasonic frequencies, cannot be heard by the average human ear. Therefore, the correct answer is A) 500Hz. The ear is most sensitive at frequencies where speech is most commonly found, which is approximately between 500Hz and 4,000Hz. This range is where the majority of the tonal content of human speech occurs, and the ear has evolved to be most sensitive to these frequencies to facilitate communication.
