Using specialised equipment, you send out a pulses of sound. You have a collecting device where the echoing sound is picked up. You can therefore work out how long sound takes to travel to the reflecting object and back to you. If you know the velocity of sound in the medium, you can work out the distance travelled by the sound in that time and so the distance to the object is half that distance.
