WebA "Hydrophone" is a device which will listen to, or pick up, the acoustic energy underwater. A hydrophone converts acoustic energy into electrical energy and is used in passive underwater systems to listen only. ...

Explain the difference between reflection and refraction. 2. In the marine seismic acquisition example shown, you are interested in two events observed in the seismic trace that is recorded at the first hydrophone. One is a first-order multiple (double bounce) off the seafloor. haley fountain

The first submarine to be detected and sunk using a primitive hydrophone was the German submarine UC-3 on 23 April 1916. UC-3 was detected by the anti-submarine trawler Cheerio as the Cheerio was directly over the UC-3 ; the UC-3 was then caught in a steel net dragged by the trawler, and sank after a large … See more A hydrophone (Ancient Greek: ὕδωρ + φωνή, lit.
