What is a Hydrophone? - Seis Tech

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 sound wave. A hydrophone can detect airborne sounds, but will be insensitive because it is designed to matc… WebChoose your weapons. The choice of transducer would seem to depend on what you want to measure – an accelerometer for measuring acceleration (VDV, MTVV, etc)and a geophone for measuring velocity (PPV). This complicates the instrumentation, so it would be nice to use one for the other. mine rush free game https://kmsexportsindia.com
