Noise Control Engineering & Superyacht.me Shipboard & Marine Noise Control – Summary of Services Any ship, whether it is a small Superyacht, Workboat, or a Military Aircraft Carrier, can be a very noisy place; ask anyone who works on one. Smaller vessels (60 to 300 feet) have high power machinery (diesel engines, pumps, large hydraulic systems) just feet away from sleeping cabins, offices, and control rooms causing high noise levels. Larger vessels can also have high noise in compartments near large machinery and propeller/thruster sources. HVAC and other auxiliary machinery or specialized sources (such as aircraft) can also be an important factor elsewhere in the vessel. Noise control is a critical factor for the marine industry since quiet ships lead to improved crew morale, lower long-term hearing loss, improved crew performance, and reduced crew fatigue. NCE is a leader in the field of Marine Acoustics. We have provided technical assistance on hundreds of vessels; our clients include naval architects, shipyards, government organizations, and private owners and operators. NCE’s staff has authored more than 50 papers on shipboard noise, including the “Design Guide for Shipboard Airborne Noise Control”, an industry-standard published by the Society of Naval Architects and Marine Engineers in 1983 and its Supplement sponsored by the U.S. Coast Guard published in 2000. Services offered to Naval Architects, Shipyards and Marine Operators are: AIRBORNE NOISE ANALYSISAccurate noise predictions anywhere on a vessel can be performed based on a ship’s general arrangement, typical structural details, and machinery arrangements and details. NCE uses our own Designer-NOISE™ and other software products/tools (many of which were developed in-house) for the prediction and control of shipboard noise. STRUCTURAL ANALYSIS/FEANCE can predict potential low frequency ‘habitability’ and structural vibration problems
