If you’re wondering how to soundproof your room, you’re in the right place. To point you in the right direction, we’ve created this comprehensive guide. We’ll use plain English to talk you through the process and help get you started on your soundproofing project.
Step 1. The Walls
When it comes to soundproofing walls, there are numerous strategies to get the job done. We’ll highlight a few of our preferred methods. These techniques will efficiently create the solution you’re looking for at a lower cost.
This is one of the simplest possible methods. Adding mass helps reduce the transmission of unwanted sounds at a fraction of the cost of more complex methods.
Quiet Barrier® soundproofing material is one of our most popular wall soundproofing materials. This material is heavy, flexible and non-porous and works to stop sound energy by dampening its vibrations. By comparison, it’s more effective at reducing noise than steel and other common building materials.
This material can either be nailed to bare studs during construction or can be applied to existing drywall with the convenient peel-and-stick backing. You can also attach furring strips to drywall, place this material on top of the strips, and then cover both with a second layer of drywall. Make sure to seal up all the seams and cracks with caulk or barrier tape.
Cotton batts work slightly differently. They don’t block noise, but they do help absorb it as the sound waves bounce back and forth between walls.
We recommend using our Quiet Batt™ Soundproof Insulation. Not only does this help stop those noise transmissions, but it also helps insulate. It’s made of 80% recycled content and is easy to apply between wall studs without any special equipment.
This is one of the most popular methods available today. Since sound normally travels between rooms along the studs shared between walls, isoTRAX™ Soundproofing System creates a “floating” mounted wall between the studs. This means there are no longer any common studs between the rooms for sound to travel along.
This system is easy to install, increases wall strength and provides great soundproofing quality.
Walls can be soundproofed whether they are brand new walls still under construction or whether they are already existing walls. The process is similar for both situations, but slightly different. Because of this, we’ve divided this section in two. First, we’ll discuss how to soundproof brand new walls.
The process of soundproofing your new walls begins once you have the bare, brand new stud walls. On one side of the wall, you’ll carefully mount the Quiet Barrier® HD. The best way to do this is to nail it directly to the studs themselves using 1.25-inch roofing nails. Make sure that the seams of the Quiet Barrier™ pieces are fitted together as closely as possible. The idea is for the seams to be virtually invisible.
To make sure this is secure and there are no gaps, use the Quiet Barrier® tape and to firmly secure all the seams in the Quiet Barrier®.
From there, you’ll need the 0.625 inch Type X gypsum board. This is going to be installed with 1.875-inch coarse thread drywall screws. This works best if the screws are placed about 10 inches apart. Be sure to leave a quarter inch of space between the gypsum board and any adjoining floors, ceilings or walls.
You’ll then install the Quiet Batt™ soundproofing insulation between the studs. On the opposite side of the wall, the isoTRAX™ Soundproofing System get installed onto the studs.
The same gypsum board then gets installed over the isoTRAX™ system, this time using 1.25-inch fine thread drywall screws. Place these screws approximately 12 inches apart, and leave that same quarter inch break between the gypsum board and any adjoining surfaces.
This quarter inch gap is then filled with OSI® Pro-Series® SC-175 Acoustical Sound Sealant. For the final touch, be sure the gypsum board is finished according to industry standards.
If you’re working with walls that already exist, then it’s going to be a slightly different process. Since you can’t start from scratch, the goal here instead is to modify what already exists.
You’ll need to start by using a stud finder to locate the studs in the wall you’ll be working on. Mark these with chalk or pencil for easy reference.
From here, the process begins to look similar. Install the Quiet Barrier® HD in the same way as instructed with the new walls. Use the same roofing nails to attach the Barrier to the studs and try to line the seams up as neatly as possible. Seal all the seams firmly in place with the Quiet Barrier® tape.
As before, you’ll install the isoTRAX™ soundproofing system over this barrier layer. The instructions for installing it are the same as they would be with a new wall.
With already existing walls, however, you’ll also need to install the Echo Absorber Acoustic Panels between the rails of the isoTRAX™ system. On top of this layer, install the gypsum board in the same way you would with a new wall, using the same drywall screws.
Finish the wall off by filling in all the gaps with OSI® Pro-Series® SC-175 Acoustical Sound Sealant. Make sure the gypsum board is finished according to industry standards.
