The traditional three-body yacht is mainly composed of the hull, two pontoons, signal lamp, propeller, lighting device and control equipment,powered by a diesel or gasoline engine, the yacht makes a lot of noise when it works.The turbulence generated by the propeller of a traditional yacht increases the noise of the yacht, and the infrasound water ripple vibration generated by the propeller travels a long distance and causes the loss of energy.When the propeller speed entered the resonance frequency region, the vibration of the resonance frequency wave also caused serious damage to the ship's electromechanical equipment.
While climate change, ocean acidification and pollution may pose more serious threats to Marine ecosystems, researchers fear that ocean noise could be the last straw.These threats go hand in hand with a severity greater than 1+1=2.""Says Lindy Weilgart, a biologist at dalhousie university in Canada.
Fortunately, noise is easier and can be reduced more quickly than ocean acidification and fossil fuel use.The sound-absorbing cotton produced by FSC company can solve the noise generated by yachting.It is made of PET/PP fiber, which is mixed evenly and formed by non-spinning process.The porous structure of PET/PP sound-absorbing material can absorb acoustic energy and reduce the transmission of noise.High sound absorption efficiency, good sound insulation performance;Good fire resistance, flame retardant level A, self-extinguishing from fire, no spread, and smokeless, no toxic gas generation;After many experiments, the product is harmless to human body.
The sound-absorbing material which is produced by FSC company,is a recyclable product, not easy to aging.The product comes with backing glue, which is very convenient to use.To a certain extent, the use cost is reduced.
