Reducing Wind, Engine, Exhaust, and Tire Noise Using Sound Absorbers

       Sound Absorbers are next and third on the list of sound treatment products to be installed into a vehicle. Sound absorption is pretty simple for the most part. Acoustic absorption converts airborne noise into another form of energy, therefore reducing the overall noise level in the vehicle. An open-cell or fibrous materials are two typical types of acoustical absorption products. The thickness, density, size of the fibers or open cells, and more contribute to what frequencies are absorbed and how much they are absorbed. Higher frequencies are easier to absorb than low frequencies. However, some products can effectively absorb relatively low frequencies in a vehicle, such as our ResoNix Fiber Mat 25 & 45, and our ResoNix Guardian and ResoNix Lockout. Both have two different areas and reasons for application, so we will break them down individually.

       As mentioned earlier, ResoNix Fiber Mat 25 & 45 are both sound absorbers and a decoupling product. Our ResoNix Fiber Mat products are made out of microscopic synthetic melt-blown fibers that are formed into a mat, have a peel-and-stick adhesive on the back, are 100% okay with being installed in the harshest automotive environments and will not grow mold or mildew, and are naturally hydrophobic. They handle water, heat, cold, and anything else just fine, so ResoNix Fiber Mat can be installed practically anywhere without worry. They are typically used on door panels, quarter panels, rear decks, roofs, wheel wells, fender liners, pillars, sometimes even floors, trunk floors, and anywhere else you can think of.

       Next up, ResoNix Guardian and Resonix Lockout. These newer products from ResoNix Sound Solutions are a familiar concept to some that has been further improved. Guardian is a composite-style material that consists of ¼” Hydrophobic Melamine foam, 1/8″ thick 1lb Mass Loaded Vinyl (aka MLV), another layer of 1″ Hydrophobic Melamine, and an Acoustic Polyester Facing. It features a peel-and-stick adhesive for easy installation. This product is multi-faceted, and ResoNix Lockout is a stripped down version that just features the Hydrophobic Melamine that is topped with the Acoustic Polyester Facing, as well as the same peel-and-stick adhesive.
