Question

For which range of frequencies, human ears are most sensitive?

• A. $2Hz$ to $3Hz$
• B. $20Hz$ to $30Hz$
• C. $200Hz$ to $300Hz$
• D. $2000Hz$ to $3000Hz$

Answer 1

The correct option is D $2000Hz$ to $3000Hz$

The human auditory system is sensitive to frequencies from about 20 Hz to a maximum of around 20,000 Hz, although the upper hearing limit decreases with age. Within this range, the human ear is most sensitive between 2000 and 5000 Hz, largely due to the resonance of the ear canal and the transfer function of the ossicles of the middle ear.
The high sensitivity region at 2000 - 5000 Hz is very important for the understanding of speech.
