Infrasound is sound of frequency below 20 Hz, too low for the human ear. Sound above 20,000 Hz (20 kHz) is ultrasound. Animals differ in the range they can hear:
Infrasound — rhinoceroses, elephants and whales, which also use such low sounds to call to one another over long distances
Audible range — human beings, about 20 Hz to 20 kHz
Ultrasound — bats and dolphins, which use it to find their way and their prey by echolocation
