What is the audible frequency range of the human ear?

Options

  • A. 2 Hz to 200 Hz
  • B. 20 Hz to 20,000 Hz
  • C. 200 Hz to 2,000 Hz
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. 20 Hz to 20,000 Hz

Detailed Explanation

The normal human audible frequency range is approximately 20 Hz to 20,000 Hz (20 kHz). Sounds below 20 Hz are called infrasonic sounds, while sounds above 20 kHz are called ultrasonic sounds. Human hearing sensitivity varies with age and individual conditions. This frequency classification is important in physics, acoustics, medical ultrasound and communication technology.
