Sound waves with frequencies less than 20Hz are called infrasonic or subsonic and those with frequencies above 20kHz are called ultrasonic. They do this by "speaking" and hearing with infrasonic waves which we cannot hear but can bend around obstacles rather than being absorbed like normal sound.

Answer 2

Ultrasonic:- SONAR (Sound navigation and Ranging). , a technique used by mariners to locate underground object, or to check the depth of the sea...

Infrasonic- Well, dolphins communicate through this sound, So, you can say if there were no infrasonic sounds, then the dolphins could not communicate....(a joke) ..

Properly, infrasonic sounds are used to take precaution against the incoming earthquake. You see, before an earthquake comes there are weak vibrations.... which can be detected and precautions can be taken
