Different types of sounds have different frequencies Human can hear a sound of frequency between 20 to 20,000 Hz Sound with frequency out of this range can't be heard by humans

We have also learnt of a property of sound that is frequency and its SI unit is hertz (Hz) . and humans can hear sound frequency from (20 Hz -20,000 Hz) if in case the sound frequency is less than 20 Hz or more than 20,000 Hz we cannot hear it that's why every time the sound produced by every vibrating body cannot be heard .
