3.4 Audible Frequency Range

Humans can typically hear sounds within a specific range of frequencies. This range is approximately from 20 Hz to 20,000 Hz.

Frequency is the number of sound wave cycles that occur per second, measured in Hertz (Hz). A higher frequency corresponds to a higher pitch, while a lower frequency corresponds to a lower pitch.

The human audible range is not uniform across all ages and individuals, but the typical range is:

  • Lower Limit: Approximately 20 Hz
  • Upper Limit: Approximately 20,000 Hz (20 kHz)
Parameter Value
Typical Audible Frequency Range for Humans 20 Hz - 20,000 Hz (20 kHz)
Lower Frequency (Low Pitch) 20 Hz
Higher Frequency (High Pitch) 20,000 Hz (20 kHz)

Frequencies below 20 Hz are generally infrasonic and are not typically audible by humans. Frequencies above 20,000 Hz are generally ultrasonic and also not typically audible.
