WebAbstract. 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 ... WebHydrophone. 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.
WebCurrently, hydrophone calibration is a magnitude only measurement, but metrological improvements offer the possibility for measurement of hydrophone phase. As a logical extension to waveform deconvolution, the influence of phase response and the impact that this has on measured data is also Web21 nov. 2024 · 1 It it’s in the wave file then you need to know the offset/sensitivity. 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.
Web28 okt. 2024 · Your hydrophone should be provided by the manufacturer with a calibration curve that represents its sensitivity (in V/Pa, or any sub-unit of this) as a function 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 …
Web12 apr. 2024 · Conventionally, the directivity is evaluated by surrounding the targeted elements with hydrophones in a pitch-by-pitch manner, which is time consuming and cost ineffective. It is crucial to develop an efficient and effective approach to measure the directivity of elements, which can be merged into the booting self-check stage of the UCT …
