Okay quick question for you sound experts out there. My wife and I are building our new construction house, they just finished roughing in the electrical, and I am wondering if there is anything I can do for my setup. The main living room where my a/v gear will be just so happens to be setup that the screen wall shares the master bedroom wall. To make it worse, the headboard will more than likely go against this same wall. My wife goes to bed early, and I sometimes like to stay up, watch some tv, ect.... I am toying with the idea of doing some kind of soundproofing so that the tv sound doesn't bother her in the bedroom. I'm considering using a double drywall with green glue method, but then wondered if having in-wall speakers would negate any attempt of soundproofing on the bedroom side? Its not like I would have the system turned up too loud, I AM kinda considerate... So I'm just wondering if the effort is going to be wasted, or if we should just use some sort of white noise machine in the bedroom? Thanks for the input!
There are lots of sound control items out there and different ways to skin this cat. You can easily build something that will knock out higher frequencies but the deep low bass is much more difficult. I'm using Kinetics Noise Control's Isomax clips as well as Acoustiblock 3mm barrier. Both websites show the charts and STC levels (measured reduction in sound). I just posted some pics of the Acoustiblock on my build; http://www.avsforum.com/t/1406831/hawaii-home-theater-construction/60#post_22472729
Just do a bunch of reading and I think you will find several different solutions. It just depends on how much sound you want to reduce (and at what frequencies) and how much time and effort (and materials) you want to throw at that wall. Good luck
STC ratings are not appropriate for audio playback spaces. Indeed many such ratings hide increased low frequency transmission over other products/assemblies with what would appear to be lower STC values.
