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 ... WebMiniature hydrophone Type 8103 is a small, high-sensitivity hydrophone for absolute sound measurements over the frequency range 0.1Hz to 180 kHz, with a receiving sensitivity of −211 dB re 1V/μPa. The high sensitivity and good all-round characteristics, make it ideal for laboratory, industrial, and educational use.
