    Some means to reduce acoustic noise, page 82 Introduction to the acoustic noise challenge As with any other hydroacoustic systems, the quality of the SC90 echo data and presentations are subject to unwanted acoustic noise. The echoes from any large and small target must be detected inside the noise.
  • Page 79 Preparations our end user documentation aims to help the user to make the right filter settings during operation. As for the target properties, there is nothing any of us can do with those. The signal-to-noise ratio, however, can be improved by making the correct choices during installation.

  • Page 80: Self Noise

    Simrad SC90 Installation Manual The transducer cable is long, and may pick up electric noise from generators, pumps, cooling systems and other electric or electromechanical devices. The preamplifiers are very sensitive, and they can easily pick up electrical noise from internal and external power supplies. The preamplifiers are also vulnerable for analogue noise created by their own electronic circuitry.
  • Page 81 Preparations Cavitation Cavitation is the formation of small air bubbles close to the transducer face. The bubbles appear because the local pressure becomes negative during parts of the acoustic pressure cycles. The cavitation threshold increases with the hydrostatic pressure. The noise is made when the bubbles implode.

  • Page 82: Ambient Noise

    Simrad SC90 Installation Manual thickness depends on ships speed and on the roughness of the hull. All objects sticking out from the hull, or dents in the hull, will disturb the flow and will increase the thickness of the boundary layer. When the flow speed is high, the turbulence can be violent enough to destroy the integrity of the water.

  • Page 83: Electrical Self Noise

    The energy reflected from these "unwanted" objects is referred to as reverberation. Reverberation is generated when the echoes from your SC90 transmission are reflected not only by fish and valid targets in the water, but also from the seabed and from the sea surface.

  • Page 84: Some Means To Reduce Acoustic Noise

    Some means to reduce acoustic noise Several factors are contributing to the performance of the hydroacoustic equipment used on board a vessel. Careful planning of the SC90 installation may reduce the acoustic noise. Unfortunately, it is impossible to simply provide a number of specific procedures to reduce the noise.
  • Page 85 • Make sure that all units are properly grounded, as this is important to avoid electrical noise. • Use shielded cables with correct grounding. • Separate SC90 cables from other cables with high voltages, large currents or transients. • Place all high voltage power cables in metal conduits.
