Industry

Problem:

Airborne noise stemming from an industrial sound source is hazardous to the long term health of its surrounding employees. It also lowers worker morale and productivity, increases stress, promotes turnover, and lessens the quality of product output.

Goal:

To drop your existing sound pressure readings down to under 85 decibels when measured over an eight hour period in order to meet standard OSHA requirements and provide a safer working environment for all employees.

Solution:

Break your application into parts.

1. First, explore any opportunity you have to treat any noise SOURCE in your plant with full or partial enclosures around any machinery. NetWell will show you how to apply its BARRIER materials and drop an average 15-20 decibels from your current levels.
   Note, however, that 90% of all industrial noise sources CANNOT be enclosed, and that results will vary depending on variables unique to your application!
2. Second, take all remaining unencloseable noise sources and attack the PATH their noise is taking as it reflects around your facility. A variety of ABSORPTION products exist for this treatment. Be sure to consult with NetWell over product selection, quantities and installation techniques for maximum performance.

   Note: Treating industrial airborne noise will yield an average 3-8 dB drop. Remember also that decibels are algorithmic, and that a mere 3 dB drop will actually cut your sound pressure levels by 50%!

Products:

BARRIER MATERIALS FIRST!
• QBS-1 Blankets are industrial strength noise barrier curtains cut to size and designed to drape around your noise source for full or partial portable enclosures. Suspended either from the facility ceiling or a frame, these fire rated blankets should yield a 15-20 dB drop if properly designed and installed. Holes, slits, patches and windows can all be cut for user friendliness. Ideal for treating stationary industrial noise sources such as compressors, furnaces, grinders and more. Also ideal for portable partitions to section off one noise infested bay of a plant from the rest of the facility, or to drape against a sheet rock wall to protect an adjoining office.
• dB-Bloc is a thin, weighted vinyl material that is sewn into the interior of the QBS-1 blankets. This barrier material can be ordered by itself, and applied to any wall surface separating employees from a noise source.
• NetLag Ductwrap is a ill thick fiberglass batting lined with the dB-Bloc vinyl and coated with an aluminized mylar skin. Ideal for jacketing around any industrial ductwork or piping where airflow or liquid flow create an unwanted noise problem.
• FBF-lM Panels are 4'x4' sheets of a layered acoustic material designed for self installation to interior wall surfaces of a home made box or shroud enclosing a stationary noise source. Simple to cut and glue, with a 15-20 dB drop!

NOW TREAT THE AIRBORNE NOISE!

Polyurethane Foam panels are popular industrial products for wall treatments. The panels dissipate noise by eliminating echo. They convert sound energy into kinetic energy. Thicker material will attack lower frequency sound sources and impact noise. They can all be glued with silicone based adhesives or put up with velcro to nearby walls surrounding your industrial noise source. For oil infested areas, ask NetWell about our Hypalon skin treatment to protect the foam for long term wear. There are several choices available to you using this core material, all available in either charcoal, blue, beige or brown colors. All polyurethane foam products are UL94 HF-1 fire rated, or can be cut out of Melamine foam to meet class A fire requirements:



• WEDGES are non symmetrical 2'x4' panels cut into an eggshell convolute on its face. Available in 2",3" and 4" thicknesses.
• PYRAMIDS are symmetrical 2'x2' panels cut into a pyramid bevel designed. More aesthetic than the wedges, and available in the 2,3 and 4" thicknesses.
• MAX SOUNDBLOCKS are symmetrical 12" x 12" cubes of thick foam designed to treat low bass noise, impact noise, or for lining enclosures around sound testing chambers for maximum anechoic affect.
• BAFFLES are 2'x4' baffles designed for vertical suspension from your facility to capture airborne noise above your noise infested area. Ideal for larger plants where no nearby wall surfaces are available, or as a compliment to wall treatments where additional absorption is required.

  

• FIREFLEX Melamine Foam panels are class A fire rated foam panels designed for acoustic treatment in high temperature areas or where open flames exist. Also appropriate as a foam treatment in any public facility. 2'x4' in size, and available in multiple thicknesses.
• VET BAFFLES are fiberglass panels cut into 2'x4' pieces and grommetted in the corners for vertical suspension around a noise source. Available in multiple colors, and ideal for airborne sound absorption where moisture or oil mist is prevalent, or where a dust free environment is a must such as over a printing press.
• USDA PANELS are approved for use as absorption wall panels, baffles or lay in ceiling tiles in any facility requiring a clean room rating. Applications include food processing plants, kitchens, pharmaceutical plants.

To Do:

• Check further web site pages on any of those products for more information, application photos, spec sheets, color charts, and references.
• Measure your room dimensions.
