20 Hz to 20000 Hz is the audible range of the average human ear.
A healthy person's average hearing frequency range is about 20 Hz to 20000 Hz. Frequency less than 20 Hz is called infrasonic, which is audible to some animal species like elephants and whales. In contrast, a frequency of more than 20000 Hz is called ultrasonic. The frequency of waves is defined as the number of waves that pass a fixed point per second. The unit of frequency is Hertz.
