http://hightechincusa.com/products/hydrophones/ WebNoise is not linear along the frequency spectrum, so professional hydrophone self-noise is usually expressed as an SPL Equivalent Noise at a specific frequency: usually 1kHz (dB, re 1μPa/√Hz). Smaller numbers like “42 dB” are better than larger numbers like “55 dB”. Sometimes noise is expressed in relation to “Sea State Zero ...
WebHydrophones can have a number of features. An integral preamplifier boosts hydrophones’ output from a small to intermediate level so that the signal may be further processed without significant degradation. Acceleration noise compensation is designed to cancel or reduce noise generated from movement of hydrophones underwater.
