Echo is a reflection of sound that arrives at the listener with a delay after the direct sound.
Echo sounding is a type of soner used to determine the depth of water by transmitting sound pulses into water. The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with the speed of sound at the time.
