Solution

Dear Student,
Audible sound:
•These sounds have frequencies in the range of 20 Hz to 20,000 Hz .
•It can be heard by humans.

Inaudible sound (Includes both Infrasonic and Ultra Sonic sound):
•The sounds having frequency more than 20,000 hertz (Hz) are called ultrasonic or ultrasound and the sounds having frequency less than 20 Hz are called infrasonic or infrasound.
•These are inaudible sounds.
Both of these sounds cannot be heard by human beings.

Regards
