When it comes to soundproofing a room one of the most often neglected areas is the floor. If you’re going to create a home theater with high-quality acoustics than you need to make sure every square foot of space is accounted for – including the ones you walk on.
Creating a sound proof environment really isn’t difficult but can not be overlooked. It’s very easy for a home theater system complete with televisions, gaming systems, and extra speakers to transmit noise. The noise will travel through the floor and if it is a common surface (ie. on the main floor of your home) then the sound will transmit to other rooms throughout the home with relative ease.
The solution to soundproofing your home theater floor is to add a layer of soundproofing material underneath the floor surface. While some soundproofing consultants recommend laying down some mass loaded vinyl we know you’ll have better results if you simply apply some Green Glue to the surface before you put down your carpet, linoleum, or hardwood floors.
Remember – in order to effectively soundproof a home theater you must address all 6 surfaces (all 4 walls, the ceiling, and the floor). You won’t have a perfectly compeleted theater until you’ve done so.
