What are Sonar Hydrophones?
Sonar hydrophones are the underwater equivalent of microphones. They act as a passive listening device which is capable of converting acoustic pulses into electrical signals, which can be read by a sonar operator. Sonar hydrophones are widely used in the military and civilian world, and are an integral part of the sonar system used to navigate ships at sea. Generally, sonar hydrophones are very durable and capable of years of use. Sonar itself works by sending out pulses of sound energy underwater which bounce off objects in their path, sending back an acoustic picture of the terrain. Sonar has been used since the turn of the twentieth century to assist with navigation, finding fish, and locating objects on the ocean floor. Sonar technology has only become more advanced since then, allowing operators to see a much brighter and clearer picture of what is in the ocean around them. In addition to improving the safety of nautical navigation, improved sonar has paved the way to many groundb
