Recordings made with hydrophonic microphone (home-made or not) A “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. Hydrophones are usually used below their resonance frequency over a much wider frequency band where they provide uniform output levels.
