Most hydrophones … Web27 aug. 1998 · A compact hydrophone with a radially-poled sphere is investigated using inside and outside electrodes. Characterization of these hydrophones is done through measurement of hydrostatic piezoelectric charge coefficients, free field voltage sensitivities (FFVS) and directivity beam patterns. WebA hydrophone measures pressure fluctuations, and these are usually converted to sound pressure level (SPL), which is a logarithmic measure of the mean square acoustic pressure . Measurements are usually reported in one of two forms: RMS acoustic pressure in pascals (or sound pressure level (SPL) in dB re 1 μPa) farmall 45c series ii
