Mass Loaded Vinyl (MLV) sounds like something tough and effective at noise reduction, because it is tough and effective. A greener, more viable alternative to lead soundproofing, MLV barriers are composed of salts, sands and tiny metal particles that give it sound reducing properties similar to old lead sheeting, but without the stigma associated with Lead based materials.

The goal of MLV soundproofing is to add dense mass to an enclosed area so that sound waves are blocked from passing through ceilings and walls. In fact, you’ll find MLV soundproofing material in music studios serious about quality sound control.
