If an object is in the path of the sound pulse, the sound bounces off the object and returns an “echo” to the sonar transducer. If the transducer is equipped with the ability to receive signals, it measures the strength of the signal.

Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water (bathymetry). 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 … See more German inventor Alexander Behm was granted German patent No. 282009 for the invention of echo sounding (device for measuring depths of the sea and distances and headings of ships or obstacles by means … See more As well as an aid to navigation (most larger vessels will have at least a simple depth sounder), echo sounding is commonly used for fishing. Variations in elevation often represent places where fish congregate. Schools of fish will also register. A See more • Acoustical oceanography • Alexander Behm – inventor • AUV See more Distance is measured by multiplying half the time from the signal's outgoing pulse to its return by the speed of sound in the water, … See more In areas where detailed bathymetry is required, a precise echo sounder may be used for the work of hydrography. There are many considerations when evaluating such a system, not limited to the vertical accuracy, resolution, acoustic beamwidth of the … See more Media related to Echo sounding at Wikimedia Commons • "How Echoes Tell Depth of Water Under Ship" Popular Mechanics Monthly, July 1930 See more WebAn echo sounder is used to determine depth of water by measuring time between transmission of acoustic waves and receiving reflected waves.

This device is commonly used by fishermen to find fish. The echo sounder sends out a pulse of sound and then listens for the echo of that pulse. The time it takes for the echo to return tells the fisherman how deep the object is. WebEcho sounding. High frequency sound waves can be used to detect objects in deep water and to measure water depth. The time between a pulse of sound being transmitted and … cuffing up
