Question

what is the frequency of audible sound​

Answer 1

The SI unit of audio frequency is the hertz (Hz).The generally accepted standard range of audible frequencies for humans is 20 to 20,000 Hz.

Answer 2

The frequency of audible sound is 20Hz to 20,000Hz.

Important Points:

• Sound is a vibration that propagates as a wave. Sound waves require a medium for their transmission from one place to another place.
• Sound waves are longitudinal waves. In longitudinal waves, the particles of the transmitting medium vibrate in the same direction as wave propagation.
• The frequency of sound waves is the number of times per second the sound pressure wave repeats itself. Different sounds have a different frequencies. Humans can hear sounds that lie in the frequency range of 20Hz to 20,000Hz.
• Sounds waves having a frequency below 20Hz are called infrasounds. Sound waves having a frequency above 20,000Hz are known as ultrasounds.
