Debunking Soundproofing Myths: Walls Make Noise

noiseSay what?

Yup, it’s a very common soundproofing myth and it’s one we’d like to nip in the bud right away. While many walls will allow sound to pass through, possibly even amplifying the noise you’re hearing, the truth is that the wall itself is not the actual cause of your sound problems.

Not primarily, anyway. It can be a secondary cause, but it will never be the main cause. One of the first things you should do if you think a wall is making noise is check that wall to see if there is a window in it. In most cases, the window itself is the culprit and the wall just happens to “be in the wrong place at the wrong time.”

Most walls have an STC value of 40. Windows generally do not. If your window does somehow have an STC value of 40 or greater, you can start to look at the walls right away. That’s usually not the case, though.

When seeking the source of your noise problem, the order of priority should be as follows:

  1. First, the windows.
  2. Second, the doorways.
  3. Third, the construction of the walls themselves.

Always check for problems in this order. Doing so will save you tons of time (and probably money).

Now that you have identified the problem, you’ll want to do some research on the basics of soundproofing so that you can pick up the materials you need to make corrections in your home. If you’re interested in learning more about the principles behind the art, check out some of our soundproofing articles. You have a lot of options when it comes to materials including resilient sound clips or Green Glue.  For a door problem, for example, you can simply use some door gaskets and caulking to fix gaps after replacing your hollow door with a solid one.

Windows may need professional attention, but you may be able to simply reseal the windows with acoustical caulk; or maybe even add an extra layer of glass.

Follow the rules of order above and you’ll find it’s much easier to figure out where your noise problems are coming from. Research first; soundproofing second!
