Many of these soundproof installations are actually quite easy to follow through and don’t require removing drywall. They’re also a great DIY project for you, your friends, and your family to work together to achieve a helpful goal. Let’s have a look below to find out what you can do.

2) Acoustic foam panels
The foam panels are specially shaped with grooves and ridges that help with sound vibrations, as well as being easy to cut and install.
These acoustic panels are excellent noise absorbents, and they can help dissipate incoming and vibrating impact sound as well.
Its lightweight and customizable features make it one of the most resourceful materials to soundproof an existing wall.
3) Foam mats
This reduces their impact noise resistance by a bit, but there isn’t too much of a difference.

You can cover an entire wall easily with a few rolls of foam mats.
Their installation is also super easy, and many of them come with a special adhesive to make installation almost seamless.

4) Install a drywall
Drywall installation might be one of the hardest ways to soundproof an already built interior wall, but it makes up for it in overall effectiveness. A drywall is an extra layer of wall applied to any pre-existing interior or external walls.
It is one of the most effective ways to completely soundproof a room, and it can be combined with other materials easily.
The combination of MLV, green glue, and drywall installed in an existing wall will guarantee that all noise never even gets a chance to pass through.
5) Install acoustic panels
They’re more lightweight than drywalls and come with instructions and tools to easily fix them in place.
They’re also made to absorb sound and noise vibrations with ease, making them one of the best ways to soundproof a wall that’s already been built.
ATS acoustics is the seller and manufacturer of one of the highest-rated acoustic panels on the market.
Their panels come with a wooden frame to allow for a beginner-friendly installation.
6) Green glue for soundproofing interior walls
Green glue is a soundproof damping compound that is perfect for filling up cracks, gaps, and holes, in your existing walls.
It perfectly complements drywall, acoustic, and foam panel installation by being the main filler substance that also adequately holds them in place.
Green glue is widely available and sold by its producer Green Glue Company.
7) Try Acoustic blankets on interior walls
They’re essentially heavy blankets that are filled with a certain material that helps them dissipate and absorb sound.
They work great in complement with other soundproofing materials like soundproof paint or curtains, and they’re easy to mount and unmount.
We’ve found a top-rated grommeted industrial blanket that is made specifically to soundproof all forms of sound.
8) Soundproof curtains
This makes soundproof curtains a great complement for soundproofing a wall.
If you have put up some foam mats and you still don’t reach the desired noise reduction, you can place a soundproof curtain to cover the wall.
That way you can achieve even more efficient sound deadening within your home.
They’re also very easy to install and come in many different colors and sizes. We recommend these great Warm Home Designs room divider curtains.
They are made with a high-quality sound deadening material that looks and feels like other fabrics.
9) Soundproof paint for your walls
It’s very easy to apply to the existing interior and exterior walls, and it can have some great results.
It’s also perfect as a before or after material, meaning that you can apply a coat of soundproof paint to an already built wall before placing some MLV in it.
Or you can use it to paint your drywall or acoustic panels after installation. This soundproof paint by Hy-Tech Thermal Solutions is very reliable and effective.
