![]() The higher the number, the more sound it attenuates. ![]() To measure a material’s ability to attenuate sound passing through it, we use a rating called Sound Transmission Class (STC). Impact sounds, on the other hand, require spongy materials or decoupling hard surfaces with softer ones. While mass loaded vinyl will help with both, it’s more useful for airborne sounds because most waves don’t go through, and dissipate when they come into contact with it. The molecules of this product are flexible, making it easy to install at all. Mass loaded vinyl products are thin and flexible, so you can build an excellent barrier without. MMT Acoustix MLV Mass Loaded Vinyl is heavy due its high density and greater mass. Excellent Noise Barrier for its Thickness because MLV is so dense, it is extremely thing relative to its soundproofing ability. You can get up to 35 STC by using 2lb per sq ft and 1/4 thickness however, this is slightly more difficult to work with. We are very particular and produce only the best quality mass loaded vinyl available. At even just ½LB per sq ft, MLV can produce a 25 STC rating, which is 1/16 thickness. We use different methods to block and/or absorb impact and airborne noises due to their differing energy levels when passing through structures. Mass Loaded Vinyl (MLV) is an effective material to use in lining soundproofing curtains or blankets. The footsteps create vibrations, which pass through the floor and come out the other side as sound waves. Impact noises come from an object hitting a surface, such as footsteps on a floor. Sound Safe is a reinforced, smooth, flexible mass loaded vinyl (MLV) soundproofing acoustic barrier specifically designed to reduce noise transmission.Common examples are TVs, people talking, and music from speakers. Airborne sounds are waves that travel through the air into surfaces (such as a wall).They are generally cheaper than multiple layers of drywall, much faster to install, and are significantly more effective at blocking low-frequency noise. Highly recommended for soundproofing walls, floors. Best uses of Mass Loaded Vinyl While stacking drywall layers may get you to an STC 40-45 range, Mass Loaded Vinyl is a great option if STCs of 50 or higher are needed. Select weight required to see actual price and product information. Highest Quality 3.7kg/m2 Mass Loaded Vinyl, flexible acoustic barrier, 1000mm wide 10 meters 10m2. Extra heavy duty flexible acoustic barrier for soundproofing walls, floors, ceilings, cars, boats & truck linings. MLV 1 has a standalone sound transmission class (STC) rating of 26, and MLV2 has a standalone STC rating of 32. Thermotec NuWave Base Mass Loaded Vinyl (MLV)- A Heavy Density, barium loaded acoustic insulation for walls, floors & industrial. We can divide sound waves into 2 types: airborne and impact. MLV 1 is even thinner, at 1/8 inch thick.
