![]() ![]() over the years I personally think that using Thinsulate acoustic insulation works better and is WAY lighter than the mass loaded vinyl. So just depends on what you're trying to do. One day I hope to remove the tires and liners to add some Dynamat to the area. Most of the true "audiophiles" I know are running stock setups in their car and listen to their music on their home set ups. But if you are trying to a create a high quality listening environment you'll be limited by the acoustics of the cab. They are all talking about the same process: reducing the amplitude of vibrations to reduce the At the end of the day, if your goal is to make your cab a little quieter and reduce road noise, you're on the right track. You'll often see these terms combined with a descriptive like sound, noise, vibration, or constrained-layer. We sometimes use different adjectives to describe the "damping" to try and make it extra confusing. The automotive industry uses the terms deadening, damping, and dampening interchangeably. Mass loaded vinyl or MLV is a material commonly used for soundproofing because of its great noise blocking capabilities and flexibility. From the article I linked: "The short answer is simple. With STC 26, our 1 lb/sf MLV can improve wall soundproofing performances by 40 or more. ![]() Mass Loaded Vinyl, or MLV, is a Vinyl-based sound membrane designed to add maximum soundproofing and dampening to your wall assembly. Mass loaded vinyl will be able to work as advertised whereas a product like Green Glue Compound would be less predictable depending on joist length, joist spacing, assembly weight, etc.You're talking out your ass a bit.

Mass loaded vinyl does not have the same issue as Green Glue Compound in this assembly because it isolates sound in an entirely different way than the Green Glue Compound. For example, a plaster wall with Green Glue Compound and a new layer of drywall over the plaster has proven ineffective because plaster is difficult to dampen (mass, rigidity). However, mass loaded vinyl does have a value over products like Green Glue Compound or QuietRock in that mass loaded vinyl will work in any type of wall, ceiling, or floor, regardless of other materials used in that assembly. The muffling is done by using a layer of closed cell foam and if necessary a layer of free-floating heavyweight material such as mass loaded vinyl. We generally only recommend mass loaded vinyl in lightweight assemblies with minimal layers of material, or for utility use in fences, doors, windows, duct, cars, etc. Damping sound is the reduction of resonance in a room through reflection and diffusion. wall assembly itself (wood studs vs metal studs, 2×4 studs vs 2×6 studs ect. MLV does not have sound absorption qualities, instead it's used for damping (viscoelasticity). Mass Loaded Vinyl (MLV) comes in 1 or 2 pounds/sq.ft. Meaning, it keeps sound confined to a space as well as out of adjoining spaces. When those products aren't an option, MLV should be considered. Mass loaded vinyl is essentially a reflective sound barrier. Although we do recommend higher performance products that decouple. I have heard tell, that what you want is 'dynamat', then a layer of closed cell foam about 1/8' as a decoupler and then mass loaded vinyl (MLV) over that. ![]()
