Broadband Acoustic Receiver (Hydrophone)
A digital Hydrophone is a passive acoustic sensor (an underwater microphone) that converts sound energy to electrical energy, with a binary stream output. The Broadband Acoustic Receiver (Hydrophone) listens for earthquakes, sea creatures, and human-generated noise in the ocean, and can hear and record everything from marine mammals in the water column to rain at the surface. The OOI requirements specified very broadband hydrophones with good noise floor characteristics and a wide dynamic range.
