A hydrophone (Ancient Greek: ὕδωρ + φωνή, lit. 'water + sound') is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a … Meer weergeven The first hydrophones consisted of a tube with a thin membrane covering the submerged end and the observer's ear on the other end. The design of effective hydrophones must take into account the acoustic … Meer weergeven • Hydrophones —Brüel & Kjær Hydrophones and research articles • DOSITS—Hydrophone introduction at Discovery of Sound in the Sea Meer weergeven A small single cylindrical ceramic transducer can achieve near perfect omnidirectional reception.

Web6 jul. 2024 · Frequency response: Usually a hydrophone consists of some sort of piezo electric ceramic that converts sound pressure into a voltage. How much voltage is produced per received pressure level (sensitivity) will vary depending on frequency. Web2 sep. 2016 · Part of the noise that limits receiving array capability is internal noise arising from thermal agitation in the hydrophone materials . This noise is a transducer characteristic that was discussed in Sect. 6.7 as part of hydrophone design ; it is incoherent and too small to be important in most ship-mounted arrays, but could be important in …
