![]() ![]() You can wrap MLV around steel columns, plumbing pipes, metal ducts, etc., to attenuate noise transmission. Unlike most soundproofing options like drywall, mass-loaded vinyl is flexible, softer, and thinner, which offers many benefits. but block out unwanted noise noticeably from interfering with your peace. ![]() This means they won’t add any visible thickness to your walls, car roof, ceiling, etc. A vinyl soundproofing material with an STC rating of 26 or 32 is only about 1⁄4 or ⅛ inch thick. They come in different thicknesses and STC values. Vinyl soundproofing material helps reduce noise by adding mass without significantly increasing the thickness of your walls, ceiling, or floor. Most architects and engineers use mass-loaded vinyl in industrial facilities and commercial buildings to muffle loud airborne and impact noises.įor the best soundproofing results, stick with an MLV that combines noise isolation, damping, and absorption. Its application is not limited to homes only. MLV is often placed between layers of drywalls or other building materials to create sound-blocking walls, floors, and ceilings. How is Mass Loaded Vinyl Used for Soundproofing?īefore you go ahead and purchase a vinyl soundproofing material for your home, it’s crucial that you know how it’s being used. Thus, mass-loaded vinyl is one of the few options that effectively blocks and absorbs multiple sound frequencies passing through ceilings, floors, and walls. The highly dense compounds are responsible for MLV’s excellent soundproofing capability. Vinyl is known for its impressive flexibility, which makes it easier to wrap around corners and tight edges. MLV is made of vinyl and natural high-mass compounds – calcium Carbonate or Barium Sulphate. Taking a look at the following study case, the noise reduction obtained goes from 40 dB to 60 dB.Mass Loaded Vinyl for Soundproofing – What is it? In the following video, you can see the way to apply liquid adhesive correctly: Ĭombinations to Make An Efficient Soundproof Wall To make sure they won’t fall off, you can use stick tabs, liquid spray adhesive or liquid adhesive. Weight and installation: Acoustic foams are very light and easy material to install.Safety: As foam is mainly made of synthetic rubber, natural latex or polyurethane, or extruded melamine, acoustic foam brands offer a fire-retardant component in their products.In a sound booth for recording audiobooks and podcasts, make sure all the surfaces of the inner walls are covered with acoustic foam panels. How Much Reverb and Echo Can Acoustic Foam Absorb: the NRC (noise reduction coefficient) is 0.50 – 1.75 on average on professional acoustic foam products.The table below shows the absorption coefficients (ASTM C423) of Auralex products: Product NRC 1″ Studiofoam Wedges 0.50 2″ Studiofoam Wedges 0.80 4″ Studiofoam Wedges 0.90 MegaMAX-Wall Panels 01 1.10 2″ Studiofoam Pyramids 0.70 4″ Studiofoam Pyramids 0.75 Venus Bass Traps 1.30 These shapes help interfere with the sound waves inside the sound booth thus absorbing reflections, reverb, and any possible echo during the recording stage. Noise Reduction Coefficient: Acoustic foam is dense and thick and it’s easy to recognize because of its peculiar pyramid pointed or wedged surface.These are the qualities of acoustic foam inside a sound booth to record audiobooks, podcasts, and many other types of voice-over audio products. The STC rating of acoustic foam is under 0.05. If you want to block sound, acoustic foam is not what you should use but mineral wool or fiberglass. Acoustic foam is a very poor noise reduction material, but excellent reverb and echo absorber inside a sound booth or recording room of a sound studio. ![]()
