The uses of infrasonic sound: The range of infrasonic sound is from 1 Hz to 20 Hz. Men cannot hear this sound but some animals can hear it. Elephants communicate with each other using infrasonic sound. This sound can travel a long distance without any change. This type of sound is produced during earth quakes and nuclear explosions and destroys many things with great shake.
