What is the best method to muffle the hardwood floor noise in the basement.

The entire main floor is hardwood and the plan is adding R30 insulation, but curious if a foam board insulation between the R30 and the sub-floor will help. Any suggestions are welcomed.
Thanks, Gary

    I wrote an article about this a while back - In my research, experts said the most effective thing is resilient channels, which are described here, and should be professionally installed:

    the insulation will help...but a physical "break" in surface finishes will also help. Look into a product called Homasote 440...this is widely used and designed just for this purpose

  • Where are you planning to put the R-30 insulation? If your thinking about doing floor between the basement and the 1st floor level and have heating or cooling system in basement area your wasting your hard earned money on that. If your using the basement and the noise is disruptive to what ever your doing in basement, You can purchase sound deadening Sheetrock that you would fasten to a metal grid system to deaden the noise. Of course putting insulation in will muffle noise as well, but you need to cover it so the glass fibers do not spread in the air if disturbed and if you use a vapor barrier you will need to cover it anyway for fire safety.

    We are adding the insulation to the bottom of the sub floor from the basement, and then we will drywall the ceiling in the office. The other areas of the basement will have a dropped ceiling. Planning on having the facing placed towards the basement area. We will install the sound deading drywall to the metal grid system

  • Do not use faced insulation here, you do not want any vapor barrier on either side. Only use where there is an outside wall involved. Not between conditioned spaces.

    Large custom-assembled soundproofing cabin can be built at site according to client detail. These cabins are intended to keep up a noise level of 63-67 dBA inside the cabin.
