This paper describes the AQUALOG 50, a statistical noise analyzer that includes a hydrophone sensor typically attached at hydrants, measurements taps or chlorination taps. The sensor is cable connected to a small acoustic data processor. The statistical noise analyzer is designed for unmanned acoustic operations during the night. The system listens for a continuous two-hour period at a single contact point.
