 Noise barriers prevent sound waves from passing-through ceilings, walls, floors, and other structures. They’re usually made of vinyl, a dense but flexible material that provides strength, durability, and resistance to humidity and moisture. Some sound barriers are made of mass loaded vinyl (MLV), a sheet material that contains salt, sand, or tiny metal particles for added mass.
Vinyl and MLV can be laminated to foams and facings that provide sound absorption, vibration control, and industrial noise control properties. Melamine, a type of acoustical foam, is often used because it’s flexible but semi-rigid. Melamine foams are also flame-resistant and lightweight. Facing materials can provide frequency attenuation, chemical or abrasion resistance, support for cleaning, and decoration.
