See the video below on how to install it. It should be installed loosely but airtight. Some soundproofing techniques you can use n soundproof walls without removing existing drywall include: Using Mass Loaded Vinyl Mat. Mass loaded vinyl is applied on the exposed studs of the wall, before the drywall is installed. Soundproofing a room is typically done during the construction phase. To fix this, acoustic panels can be installed to capture and eliminate reverb and echo in a room. Hang your drywall over the MLV, vertically or horizontally, and apply your desired finish. Sound bounces off dense material, which can create another sound issue, called reverb or echo. This product does not absorb sound, but repels it. Mass loaded vinyl is a product that has a high STC rating that when applied properly the studs of a wall, will reduce up to 90% of sound vibrations. You can buy these products at Vibrasystems in Toronto.

Decoupling is essentially inserting a medium that does not transfer energy, such as rubber, between two mating surfaces. The effectiveness of Soundproofing is increased when surfaces are decoupled. STC rating is also used in interior applications such as ceiling tiles, and mass loaded vinyl. An acoustic engineer would determine the noise level generated by traffic on the highway, then recommend a highway barrier with a specific STC value to effectively repel the sounds from the highway. An example of this would a highway by a neighbour. This measurement is useful as a standard to match products to repel sound to the environment creating the sound. The STC rating is measurement used by engineers to describe the ability of a partition to stop sound passing through.
