This is used by some bats, cetaceans, and as sonar by submarines.

A short acoustic ping is sent out, and then we listen for its reflection from a distant object. The velocity of sound in air is around 330m/s.

The bats actually send out a ping of falling frequency; so that a high frequency return pulse indicates a close object; and a low frequency return pulse, a more distant object. When an object is close, a bat increases its ping rate.

Some insects have developed avoidance behaviour to ultrasonic pings!
