Acoustic Doppler Velocimeter Application:

An acoustic Doppler velocimeter (ADV) operates by the principle of Doppler shift. This concept is illustrated by a simple example: if you are standing at a railroad crossing and a train blares its horn as it passes by, you hear the horn at a higher pitch as the train approaches, and then a lower pitch as it leaves. As the train moves toward you, sound waves from the horn are compressed (meaning higher frequency) and you perceive the sound at a higher pitch. As the train leaves you, sound waves are no longer compressed and you hear a lower-pitched, lower frequency noise.
