Can I Soundproof Hardwood Floors?

Filed under: Flanking Noise — Tags: , , — admin @ 6:47 pm

A while back we were reading some posts over at the Floor Talk! site and a reader over there had posed an interesting question. The guy in question was a condo owner and wanted to install hardwood floors but his homeowners associateion wouldn’t let him have them installed because the floors would make too much noise and disturb his downstairs neighbor.

The reader than posed the question that interested us. He wanted to know if he could use Green Glue under the new hardwood floor to reduce the noise. The answer? Not as promising as we hoped.

If you have a condo and are able to change the height of the floor, adding another layer of plywood and then the Green Glue, the effect might really be exactly what you’re looking for. Remember, the thicker the insulation the less noise you’ll hear.

In the end, though, it turns out that the Green Glue combination will only really absorb low-frequency noises but those high-frequency noises wouldn’t be absorbed. In the end your downstairs neighbors will still hear you sliding your furniture around or dropping your keys and silverware.

In this case, Green Glue is only a part of the solution. As much as we hate to admit it, if you own a condo and could potentially violate your agreements or anger your neighbors you should consider hiring a sound consultant. He or she will be able to best determine whether installing a hardwood floor is a reality or merely another dream.

Flanking Noise Paths

Filed under: Flanking Noise — Tags: — admin @ 7:14 am

Flanking noise is noise that gets into a room via means other than through the ceiling or walls. While they’re not always easy to identify they can have a huge impact on the amount of sound that enters a room.

Have you been walking around your house, apartment, or condo trying to figure out why you’re still getting a significant amount of noise in a room that should otherwise be quiet? Consider the following:

  • Is the noise coming from the floor framing system beneath your wall flanking path?
  • Is the noise coming from ceiling joists from an upstairs room or attic that sits above more than one lower room?
  • Is the noise coming from a side stud wall that attaches your apartment or condo unit to a neighboring unit?

There are, of course, other possible flanking noise paths to consider but these are some of the main ones and should be amongst the first you look for as you attempt to identify the source of the noise in your home.
