Here is a basic breakdown of the STC ratings and what they mean:Ģ0-25 Normal speech can be heard and understoodĢ5-30 Loud speech can be heard and understoodģ0-35 Loud speech can be heard, but not understoodģ5-40 Some loud speech can be heard, but not understoodĤ5-50 Extremely loud sounds (stereo, some musical instruments) can be faintly heardĥ0-60+ Almost no noise detection whatsoever The higher the STC rating, the better the material is at soundproofing. Sound Transmission Class, also known as STC, is a numeric value that rates how effective a material will block sound from getting through the other side. What is Sound Transmission Class, and How is Mass Loaded Vinyl Rated on the STC Scale? Not only will MLV act as an acoustic blanket for all of these purposes, but you can also customize it to fit your specific needs thanks to its flexible nature.
MASS LOADED VINYL ALTERNATIVE WINDOWS
To keep sound from getting in and out of home windows and doors.To quiet appliances such as AC units and dishwashers.To block road noise and other vibrations in vehicles.Here are some additional ways you can use MLV as a soundproofing barrier: It is primarily used to keep sound from penetrating through walls, ceilings and floors. Mass loaded vinyl is a cost-effective noise solution and is one of the more versatile products on the market as far as application. The vinyl makes the MLV flexible and amendable.Ĭombined, these elements create the golden standard of soundproofing because, in addition to effectively blocking sound, the vinyl can be cut, fit, and bent into various shapes and surfaces thereby ensuring maximum soundproofing efficiency. Both calcium carbonate and barium sulfate are high-dense, inert materials (sturdy material that doesn’t cause or promote change) that give MLV its durability and stability. It’s a combination of polyvinylchloride (PVC, or vinyl) and calcium carbonate or barium sulfate. Mass Loaded Vinyl is a viscoelastic material. MLV was created in the 1960s and has seen been used since to add mass to walls, ceilings, ducts, and pipes to block sound. It’s a heavy, limp sheeting material known for its high density and good flexibility - these two qualities allow MLV to dampen sound waves and vibrations. Mass Loaded Vinyl, also known as MLV, is a superior noise-blocking, non-toxic alternative to many other lead-based soundproofing materials. In this beginner’s guide to mass loaded vinyl, we’ll walk you through what mass loaded vinyl is, how it’s made, what you can use it for, if it’s safe and more. What can you do? Fortunately, there’s a simple solution to most of these noise problems: Mass Loaded Vinyl. Maybe you have the reverse problem: perhaps you have a noisy occupation or hobby-you might be a practicing musician or a DJ-and you want to spare the people around you from suffering the sounds you make.
