Soundown Boater's Basic Noise Reduction Kit - NFK1A

Soundown Boater's Basic Noise Reduction Kit is designed for lining your outboard cowl or small inboard gasoline or diesel engine compartment to achieve a reduction of 5 to 15 decibels of engine noise.

Features:

• Very effective for airborne noise pollution when properly applied
• Provides adequate soundproofing at an affordable price
• Highly efficient materials that offer the latest in advanced materials technology - used alone or together in any combination, will satisfy the majority of noise reduction requirements
• LEAD-FREE and easy to work with quality materials
• Meets or exceed Underwriters Laboratories UL-94HF-1 Self Extinguishing flammability requirements

Note: This information is offered to you as a general guide, based upon many years of practical experienced. We make no representations that these solutions will work for your specific application - The Buyer assumes full responsibility for determining the suitability of goods for his application.

• Soundproofing can be accomplished in stages, depending upon the noise level reduction that you wish to achieve
• A "complete" sound proofing job requires total encapsulation of the noise source
  • Obviously, this is not practical in most applications, and could cause engine suffocation and overheating
  • Noise Reduction Enterprises suggests you first consider those, areas such as hatch covers, engine boxes, bulkheads, etc., which are most obvious and easily accomplished - then if more noise reduction is required, continue with the remaining surfaces, such as decks, bulkheads, hull surfaces, etc., until an acceptable level has been reached
• For severe noise levels, you may have to build a sound enclosure below deck around the engine down to the bilge
  • Remember to always allow for engine cooling and air intake
• To permit future accessibility, always install soundproofing behind piping, wiring, pumps, etc. (remove & reinstall if necessary)
• Soundproofing may also be applied to the exposed side (side facing engine) or below deck fuel tanks
• Where possible, particularly in overhead areas, we strongly recommend using mechanical fasteners, batts, or some other means of mechanically attaching the material to prevent it from falling onto Hot Exhaust systems or the engine itself
• REMEMBER THIS MATERIAL IS FIRE RETARDANT AND NOT FIRE PROOF - IT WILL BURN
• The noise you are trying to eliminate is being generated by a mechanical device that also transmits vibration to all mounting surfaces. Over time, the vibration could loosen and detach the soundproofing
• The type of material selected generally depends upon the frequency range and intensity of noise pollution. Quiet-Foam (1/2" and 1") is best employed to absorb the higher frequencies usually generated by gasoline engines SuperQuiet Foam (1/2" and 1") is a composite material that offers both sound absorption and sound barrier properties, and is recommended for the low to mid-frequency noises normally associated with diesel engines
• If your noise problem is severe, you can double-up, or mix and match the materials for increased effectiveness
• In a combination, "Boater's Basic" should be mounted over "Yachtsman's Deluxe" for maximum effectiveness. Use two layers of "Yachtsman's Deluxe" for maximum noise reduction for larger diesel engines. (Mechanical fasteners supplied with kits are long enough to accommodate 2 layers of material.)
