Mlv Sound Reflective Barrier

Sound can travel through any medium-- in fact it passes through solids better than through air. Sound intensity is reduced in the transition from one material to another, as from the air to a wall and back. The amount of reduction (called the transmission loss) is related to the density of the wall-- as long as it doesn't move in response to the sound.

All walls are somewhat flexible. Any motion caused by sound striking one side of the wall will result in sound radiated by the other side, an effect called coupling. If the sound hits a resonant frequency, the wall will boom like a drum. Most isolation techniques are really ways to reduce coupling and prevent resonances.

For airborne noise, we have the perfect answer. Our Sound Barrier is an effective, relatively inexpensive treatment for airborne noise. This type of noise is primarily conversations, TV's, and any sound traveling through the air.Airborne noise, like any other, must be treated at the source. For multi-level buildings, MLV Soundproofing Sound Barrier can be used as an underlayment under the floors.

To install Sound Barrier on the floor, just lay the barrier down in lengths. Use a resilient caulking to caulk the seams between the rolls and around the outside edges of the vinyl. It can be covered with carpet pad and carpet. It can be laid directly on the floor or between sheets of plywood, or over cement. It makes floors more comfortable while also reducing noise from above and below.

There is no special application required other than caulking the seams to prevent sound leaks. For best results, lay the MLV Soundproofing Sound Barrier down first, then add padding and carpet to prevent the sound of footsteps and other airborne noise from being carried though the floor and disturbing the occupants below.

Beware of imitations. Some companies sell a similar product that tears easily and will not hold up, but offer it at a lower price. It does not pay to cut corners here. Our Sound Barrier is of high quality, will not tear or rip, and will continue to perform over time. Remember that any cracks or holes will allow sound to pass through, and are almost impossible to repair once installed. It does not pay to cut corners here, since the amount saved does not justify the compromise in quality...

Our Sound Barrier is likened to lead, as it is very heavy, wear resistant material, which adds mass to the floor, helping to keep the sound from passing through. When installed in a wall, mass loaded vinyl Sound Barrier more than doubles the STC rating. For instance, a standard hollow sheetrock wall, with 1/2" Gypsum board on metal studs has a STC rating of about 23 (ordinary conversation through it can be understood). Adding the Sound Barrier mass loaded vinyl brings the STC rating up to about 49.
