Question

The human ear is equipped to register sounds of frequencies between

• A. 20 to 20,000 cycles per second
• B. 1000 to 2000 cycles per second
• C. 5000 to 7000 cycles per second
• D. 5000 to 10,000 cycles per second
• E. 10,000 to 20,000 cycles per second

Answer 1

Answer: (A)

20 to 20,000 cycles per second

The middle ear is mainly known as a sound amplifier of the ear. It has ear ossicles to amplify the sound. The human ear can respond to minute pressure vibrations in the air if they are in the audible frequency range of 20 Hz - 20,000 Hz or cycles per second.

So, the correct answer is option A.
