An ultrasonic rangefinder sends out a short beep of sound, and measures
the time it takes for an echo to come back. Knowing the speed of sound,
it calculates the distance to the object the sound echoed off of.
It uses sound at a frequency that your ears can't hear, so the beep is called "ultrasonic".

What is meant by ultrasonic?
The human ear can hear sounds that are at a frequency of about 20 - 20,000 hertz (i.e., cycles per second). Actually it varies a bit from person to person; especially for older people, the higher end of this range goes down, that is, they can no longer hear the sounds of the higher frequencies. In any case, anything above approximately 20 kilohertz is called "ultrasound"; the corresponding adjective is "ultrasonic".
