Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water . It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight , along with knowledge of the speed of sound in water, allows determining the distance ...
Echo sounding is a process used to determine the depth of water beneath ships and boats. A type of active sonar, echo sounding is the transmission of an acoustic pulse directly downwards to the seabed, measuring the time between transmission and echo return, after having hit the bottom and bouncing back to its ship of origin.
The Bible describes lead and line sounding in Acts, whilst the Bayeux Tapestry documents the use of a sounding lead during William the Conqueror's 1066 landing in England. Lead and line sounding operates alongside sounding poles, and/or echo sounding devices particularly when navigating in shallower waters and on rivers. [3] Sounding leads
A multibeam echosounder is a device typically used by hydrographic surveyors to determine the depth of water and the nature of the seabed. Most modern systems work by transmitting a broad acoustic fan shaped pulse from a specially designed transducer across the full swathe acrosstrack with a narrow alongtrack then forming multiple receive beams (beamforming) that are much narrower in the ...

They found that the echoic memory can store memories for up to 4 seconds. However, different durations have been proposed involving how long the echoic memory stores the information once it is heard. [6] However, different durations have been proposed for the existing echo once the hearing signal has been presented.
