An audio frequency (abbreviation: AF) or audible frequency is characterized as a periodicvibration whose frequency is audible to the average human. The SI unit of audio frequency is the hertz (Hz). It is the property of sound that most determines pitch.
The generally accepted standard range of audible frequencies is 20 to 20,000Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors. Frequencies below 20Hz are generally felt rather than heard, assuming the amplitude of the vibration is great enough. Frequencies above 20,000Hz can sometimes be sensed by young people. High frequencies are the first to be affected by hearing loss due to age and/or prolonged exposure to very loud noises.
