My house is double drywalled. The master bedroom is situated beside my son's bedroom (which is sandwiched between the guest bedroom and the master). We find that when he hits the wall (while sleeping) it is very hollow sounding. I should also add, that I currently have no baseboards (recently got new floors); just not sure if this has anything to do with the noise transmission.

What are some ways to mitigate this (ideally without ripping out any drywall)? I have read about:

  • Noise-cancelling drywall adhered with green glue (resulting in a triple drywall)
  • Injecting foam insulation into the stud spacings
  • Putting up some EPS foam board and drywalling over that

Does anyone have any advice? Maybe there is a simple way to help?

This doesn't strike me as a good reason to go rebuilding walls. Even the best common soundproofing methods won't help much with direct impacts like that.

Instead, look to either prevent the activity (move the bed) or install something to protect the wall that isn't attached to the wall. I'm thinking something like a padded panel mounted to the bed, long the lines of office cubicle walls.

Dull, low-frequency sound is very difficult to contain. You need to simply keep it out of the wall in the first place.
