OK.. i tried reading the master thread on acoustica treatment but seriously .. someone needs to condense it.

I am doing a room that's 23' x 11' x 6'8" (yeah i know.. )

my #1 concern right now is sound transmission. the contractor will be ready to start work in a few weeks and i need to tell him waht materials to use and how. rear and left walls are concrete outside walls (this is a basement) with some studs on them - not sure about sheetrock yet - there's fake wood paneling on there right now, the right wall joins the stairs to the basement. the front will border a bathroom that's yet to be built.

there is existing sheetrock on the outsides of the front and right walls so there's no replacing that (i'd rahter not anyway). also, the basement ceiing will need to be all new.
currently, there's a ton of sound leaking through the ceiling (there isnt any ceiling so to speak - just bare joists). the right wall which joins the stairs also transmits sound pretty well all the way up to the second floor.

I am also on a budget so am not about to spend $90+ per sheet of quietrock or anything. the options i'm thinking are double layers of sheetrock, greenglue, resilient channels, etc. what i don't know is how much of what to use and in what combinations on which walls:)

please help asap

what the ......


people really pay that much for that soundproofing drywall? I would say two regular drywall layers will do the trick.




I have a time machine that ive been looking to sell......
know of anyone intrested?

Fastest way is to contact John or Ted @ http://www.soundproofingcompany.com/

Send them a picture and/or diagram of the room and they will figure out what is needed and then you can order all the stuff from them ;)

Here is the condensed acoustical treatment thread:

Accoustics and isolation are not the same thing (though one can help the other).

For isolation, start with this:

Fiddler,
You are on the right track when you talk about using double layers of sheetrock, and Green Glue, but you do not want to use resilient channels (RC). Go with Resilient Clips and Hat Channel.

Yes. People pay that much for a soundproof wall all the time. Except folks like ScuffyHT, BIGmouthinDC, dc_pilgrim and many more on this forum. On the other hand you probably noticed the lack of endorsement for your plan just to put 2 layers of drywall. Sure your wall will be heavier, but it will not be soundproof at all especially according to today's Home Theater standards. If you are planning on doing a sound isolation project, let us know and we'll help you in making a great performing wall.

thanks all for the quick links. generally speaking, what do you forsee the isolation costs to be considering the size of the room? ballpark figures (materials only)

Your room is about the same dimensions as my room. I used 2 layers of drywall on the ceiling. The second layer is going up next week with green glue. NOTE I did the ceiling only 2 layers, the walls are all in 1 layer of 5/8 since it is a basement.

I also was on a tight budget so feel free to look at my build as I am pretty sure yours will take the same shape.

Ted White is also my adopted guru and he has taken the time to help me tremendously along with a bunch more folks here. But if you are going to go the dbl drywall route and want to do green glue - contact him and also pick his brain.

Staffy - your build thread is great. i am totally thinking of stealing your hidden rack idea - although i'm thinking of sound panels that move, not movie posters.. but we'll see.
