Question

The range of audible frequency for the human ear is

Options

• 2 Hz to 2000 Hz

• 20 Hz to 2000 Hz

• 20 Hz to 20000 Hz

• 200 Hz to 20000 Hz

Answer 1

20 Hz to 20000 Hz

Explanation:

• Frequencies below 20 Hz are infrasonic and cannot be heard.
• Frequencies above 20 kHz are ultrasonic and are inaudible to humans.
• Hearing ability declines with age, especially for higher frequencies.
• Some animals can hear beyond this range (e.g., dogs and bats).

Thus, humans can hear sounds in the 20 Hz to 20 kHz range.
