I've googled this and all the information is aimed at soundPROOFING the walls. I'd just like to make a decent reduction in the amount of sound that passes through the walls.
The usual advice is the add another layer of drywall with some insulation between, put staggered studs so the wall board from one room does not touch the wall board in the other room, etc etc. All of these make perfect since and would be very effective at reducing the sound transmitted but they are major projects.
I'm looking for bang for the buck here.
Right now, I have two bedrooms that share a wall. One has my 1 year old light sleeper and the other my 3 year old noise maker (toys that play music and talk). Also both of these bedrooms share a wall with my living room where the TV is. To make matters worse I have some hearing damage so I need the TV a little louder than usual so I can hear what people are saying. Not blasting loud but I can't turn it down to whisper levels and make out all of the words.
The wall construction is typical with a 2x4 studs between two 1/2" drywall sheets.
Is there a product that can be blown into the walls through small (say
1-2")holes between the studs, in the top sil (non load bearing sil from in the attic) or the sheetock itself? I'm thinking of some type of blow-in insulation to reduce the sound from echoing in the dead space between the two sheetrock walls.I've seen several say that when they remodel and put plain old insulation in there interior walls with nothing else special it made a notiable difference. I'd like to duplicate that except witout removing the walls.
any ideas?
