WebIEC 60565-1:2024 specifies methods and procedures for free-field calibration of hydrophones, as well as individual electroacoustic transducers that can be used as hydrophones (receivers) and/or projectors (source transducers). Two general types of calibration are covered within this document: absolute calibration using the method of … Web30 jun. 2015 · 4. I want to collect data from a hydrophone over a period of days or weeks. A desired typical collection period would be 30 days. Hydrophones are a piezo-electric transducer that output millivolts (thousandths of a volt). A response from a hydrophone might vary from 0.001 Volt to 0.099 Volt, for example. The needed sampling rate is about …

If you don’t have it, then it’s rather impossible to obtain the actual SPL. For example if you have another recording done with the same setup and you know exactly what is the level of that signal, you could calibrate it. taylor 356ceWebIt has a wide incidence angle tolerance, making it easy to adjust the hydrophone’s angle. It is made with polymer material with a high electromechanical coupling factor and upper usage temperature limit, and is highly resistant to temperature changes, offering a stable, high level of performance.

Underwater acoustic spiral sources are able to generate spiral acoustic fields where the phase depends on the bearing angle. It allows to estimate the bearing angle relatively to a receiver by subtracting the phases of a spiral and a circular wavefront, and finds application in the bearing angle estimate with a single hydrophone, e.g ... taylor 355ce used
