What is ultrasonic sound?
Sound is created through vibrations. The number of times that a vibration occurs per second is directly related to whether we can hear the sound or not . Any sound that is created by less than 20 vibrations per second , are far too much low in pitch to be detected by human ear.
These kind of sound are said to be in sub-audible range. At the other end of spectrum , lies the sound that vibrate upwards of 20,000 times per second.
These sounds are known as ultrasonic sound and they are produced at a pitch too high for the human ear to detect. it is well known that bats and even elephants can communicate using these sounds.
