DIY Wall Soundproofing Techniques
Soundproofing new or existing walls involves adding mass behind the walls and/or something that absorbs and dissipates sound waves. Tips and advice for soundproofing walls include:
- Install your wall soundproofing materials on the side of the wall from which the noise is coming. In other words, if your kids or neighbor are making all the racket, treat your side of the wall, not theirs.
- Mass loaded vinyl, or MLV, is not just for industrial facilities where decibel levels can reach eardrum-bursting levels. MLV is a flexible material that comes in rolls you can trim easily, and it can be sandwiched between drywall layers to significantly reduce noise transmission and deaden sounds.
- Sound waves leak like water through small cracks and openings. Stop leaky noise transmission by plugging gaps and holes around switch boxes, door casings and receptacle boxes with acoustic caulk.
- Enhance wall soundproofing methods by sealing door frames with Soundproof Cow’s Quiet Door Perimeter Seals and Door Sweeps.
- Absorb those irritating sound waves with acoustic panels that not only clarify sounds within a room, but also reduce transmission of sounds through most wall types. Fabric Wrapped Acoustic Panels are fully customizable and blend in with your home décor.
Also, get to know a little about Sound Transmission Class ratings. STC ratings measure how much a particular soundproofing construction material reduces sound. Higher STC ratings indicate materials that are better at noise reduction. For example, a wall with an STC rating of 30 will allow most sentences to be heard clearly. A wall with an STC rating of 50 however, will block most loud speech and only transfer faint sounds of loud musical Instruments.
Misinformation About Soundproofing Walls
Be aware of ineffective “sound proof” construction material like:
- Soundproof paint — Promising to deaden sound or absorb mid-range sound transmissions, soundproof paint may cover faded spots or nail holes in a wall, but that’s about it. At only 30 thousandths of an inch thick, this paint won’t reduce noise at the low and high ends of the sound spectrum, making it inadequate for most soundproofing purposes.
- Soundproof wallpaper — Like soundproof paint, most soundproof wallpaper is thin and doesn’t live up to its promise of effectively reducing noise. Many soundproof wallpaper products are simply regular wallpaper backed with a minimal layer of foam or other noise deadening product. It does not control high and low frequency sound waves, falling short of adequately soundproofing a room.
- Foam rubber — The kind of foam rubber used to make your yoga mat or mouse pad won’t soundproof walls. Only specialized noise reducing materials containing foam, rubber and other sound absorption components will give you the kind of wall soundproofing needed to effectively control soundwaves.
- Carpet on the wall — unless you’re deliberately going for the eclectic or “shabby chic” look, tacking carpet on walls doesn’t effectively stop sound waves. Carpet may minimize some reverberation, but does not have the density necessary to minimize sound transfer.
