2 leaf when isolation not necessary

I have question to ask that i couldnt find answer for on this forum. I dont have to isolate my room. I just want to make it sound good. Should i put mineral wool/gypsum board construction on brick walls anyway , or should i just leave them as they are? Does gypsum/rockwool construction improve response of the room or is it only recommended for sound isolation?? You can find the 3d models of my place here: http://www.johnlsayers.com/phpBB2/viewtopic.php?f=1&t=11607 Id be really gratefull for any tips Thanks Bartek

Can you re-word your question, I don't understand sorry.

That doesn't look like it was re-worded! Gypsum board and rockwool construction can be used to isolate, or to treat. It depends on how you use it and what you need to do. Unless you explain clearly what you have, what you want to achieve, and how much budget you have, then nobody here can help you. So far, you are basically saying something like "I need to travel. Is car plus airplane plus snowboard plus parachute a good way to do that?". Try clicking here and reading this post to get you started. - Stuart -

I did reword the message but in the first place ive edited the old one. Thats why they are all the same now. I did follow all clues on how to get best feedback in my previous post, but it seems that its better not to follow them because noone have replayed me before :) . Thats my previous post (ALL INFORMATIONS INSIDE) : http://johnlsayers.com/phpBB2/viewtopic.php?f=1&t=11607 If somethings wrong - ill be happy to correct it, but ive tried to mention all important things. I just wish that someone more experienced could tell me if im going in the right direction or not. sincerely

I did follow all clues on how to get best feedback in my previous post,

Well, except maybe for this part: "Start your post with an overview of your goals and where you are in the process... Research? Planning? Construction already underway? Finished, and wanna know why it doesn't work?" And maybe this part: "HOW LOUD are you, and how picky/loud are your neighbors? How close? This is subjective, so you will need to buy something like the Radio Shack Sound Level Meter " This part too: "Include as much detail as possible about the existing construction. Having details about anatomy of your existing floor, walls, and ceiling is critical." Could be this part, also: "Group your actual questions last, and put each question in its own paragraph. This makes it easier to respond to each of your questions. " Also, this part: "Budget - without this we have no idea if we are wasting our breath suggesting things - answers like "small", "REALLY tight", "reasonable", etc, have no meaning whatever. Comments like "under $500", "prefer to keep it under $1000 but can go more if necessary", "$300-$500 MAXIMUM", will give us a clue for realistic suggestions." But now I noticed your link, to your OTHER thread, and realized that you have TWO threads going, with some info in each. That makes to really hard to know what build we are talking about, who is building it, and to keep track of details. Do us all a favor, and try to keep all your questions in one thread, or at least if you start a new thread then refer back to your main thread as "All of my details are here, in my main thread:", instead of just saying "You can find the 3d models of my place here: " The reason I didn't realize that THAT was your main thread, was because you only mentioned it as a place to find 3D models! Folks here are not clairvoyant.

Im really sorry for troubles im causing. Ive edited the previous post once again and Id still be grateful for any tips and opinions.

Your OK bleblack. Some people just like to beat other people over the head with technical data...that really should stop. "Does gypsum/rockwool construction improve response of the room or is it only recommended for sound isolation??" Yes it can improve the overall response, make it more even and adds a bit of absorption as well.

Thank you very much! And couple more questions emerged: 1. Is it better to leave some air between existing 50 cm (19.5'') brick wall and new wall made of gypsum and insulation, or would id be better to build it right next to existing wall ? (room-response-wise) 2. Would it be better not to put gypsum boards on the scaffold with mineral wool,but rather some kind of fabric, that easily lets air get trough ? Is there a risk of making room too dead that way? 3.If there is such a risk, then probably a good way to work with the room would be starting with rockwool walls only, and than adding reflective surfaces, unless achieving satisfying results? (Metering with REW during process) Am i going right way ?

gentle bump :)

I think you want to work with panels and traps and things of that nature. If you do not need isolation, then forget the sheetrock, framing(scaffold) and mass material. Search for acoustic panels and bass traps. These are things you will construct or purchase to absorb frequencies in your room. Good luck, Brien

Ok, So what you need to watch out for is vibrations in the walls, nodes and resonant frequencies. You will still need to built the room to a quality that stops vibrations. Answers: 1) Not really- the air is part of the MAM wall design. If your not worried about outside noise getting in then- no 2)You will prob add slates to liven the room any way. Inside-out walls are great for smalls room. they act as bass traps. 3)testing is always the best way to go. budget vs sound. Make sure your room ratios are good, walls angled correctly.
