I want to put Roxul and acoustical putty in the interior walls of the home my wife and I are renovating. She is worried that she won't be able to hear the kids (ages 5, 3, 0) in the next bedroom over if we do that. The home is 950 sq. ft. and has three bedrooms, all next to each other.
If I just put Roxul and use accoustical putty between the bedrooms (2x4 studs), how soundproof is it going to be? I understand that to get real good soundproofing, you have to use green glue, multiple layers of drywall, acoustical drywall, and RSI clips. I figured the Roxul and putty would just give us all a little bit of privacy without totally sealing off sound from one bedroom to the next.
