Look at the link. I want to do that to my walls in order to isolate the room. Is that a good way of doing it or should I take a different approach. Just look at the link and tell me if that is a good way of isolating it.

Concrete block is good. What is in the link would be good as the entire wall. Not something to duplicate partially. As a mater of fact the basic wall shown in the drawing would have TL characteristics shown in fig 5 of IR 586. Notice in the figure that if you put a layer of drywall on the other side of the concrete, the TL will decrease in the 80 Hz band. That is why I am asking you spell out what you mean by adding etc.

Andre (dresso),

I will make an assumption here, so please forgive me if I guess wrongly. I take it that English is either a second or co-primary language for you. That being assumed, I am guessing that some of what we are "not understanding" is due to the inherent issue of translation from your native tongue to English and then to written English on the internet. I say this because I sense frustration or irritation in your last post.

No one here, especially Andre', is trying to frustrate you. It's just that the more exacting the details you can provide, the more exacting your answer will be. Does that make sense?

Please understand that what you are really asking is not as simple as "Is this a good way" to do something.

Yes, it is a known way that will work to attach gypsum to a concrete wall. Is it a "good" way... sure. But is it the most appropriate method, or a method that will give you your desired results... THAT is the proper question.

As the other Andre (avare) has pointed out... adding gypsum to the second side of the concrete block wall (the common tracking room/control room wall) is going to actually reduce the low frequency isolation between the two rooms.

Unfortunately, with the information you have provided, there is still a bit too little detail to give you a definitive answer.

Please confirm if I understand the situation and PLEASE correct the line items individually.

1. Your proposed building is comprised of concrete block walls, both interior and exterior.
2. You wish to use the room with the closet space as your tracking room
3. You wish to use the other room as your mixing room
4. You will be tracking a wide range of musical styles
5. You would like to track everything from drums to vocals
6. You have little concern of outside noise coming in
7. You don't have to worry about your neighbors complaining about drums or other instruments late in the evening
8. You would like to have a good deal of isolation from the tracking room to the mix room.
9. The entire building sits on a monolithic slab of concrete
10. You have a working budget of $10,000 (US)

11. You want to know if you can achieve isolation on some wall (which one (or ones) is not entirely clear) by the use of standard hat channel.

Again, please help us to clearly understand your situation and your question.

I'll also ask another couple of questions...
What type of ceiling assembly do you have? (joist or truss)
What is the ceiling assembly made of? (wood or metal)
Can you supply the measurements of that ceiling framing system? (2x8, 2x10, etc)
Is there adequate insulation in the attic space? (at least R-30)
What can you tell us about your ventilation and air conditioning system?

The eye can trick the ears.

In seeing a wooden covered wall someone looking with interest might say aloud, "oh that gives the room such warmth". It didn't. But that is what the viewer got from the experience.

"...these thoughts are about why top studios look like they have parquetry all over the walls and the roof"

I think Max said it all so Bobs' your uncle or something like that.

Sorry if you sensed frustration, I probably was a little bit frustrated. You are right, English is my second Language. I´m going to work on CAD and show you what I think would work, so it´s more clear on what I want to do. To answer your questions, my ceililng assemby is joist, the ceiling assembly is made out of metal. There is no attic, and we dont have conditioning system or ventilation system because here in Guatemala is always relativilely warm, there are two windows, one on each room, and they are on the same side. Each window is 1.50 by 2 meters. The window bottom are at 1.25 m from the floor (I was planning on getting rid of the windows). Right now I do not have the measurements of the framing system but I will ask the engineer who built the building, thanks. And excuse me for my frustration, I did not want to sound mean or bossy or anything, thanks to everyone who´s helping me.

Dresso,
to build a soundproof room it _has_ to be airtight.
When something is airtight and people go into it, it needs some form of air supply.
Not an issue of heat or cold... Just suffocation.

OK, thanks for the quick reply, I don´t have a ventilation system (not yet at least). From doing a quick research I think what I would be able to put in here is an exchange chamber. I will add the ventilation system to the CAD drawing (it probably would not be exact but to give you guys and idea what i could do). Thanks again to everyone and sorry if it sometimes (or always) I get annoying with my questioins.

Your doing fine boss, stay with us.

dresso,

I seriously doubt if another person on this board who has asked as many annoying questions as I have. Confused

The folks here are interested in you getting through all the details, and having the room/situation you want.

But it's like I said... the more detailed the question, the more detailed the answer... so please ask away!

Hi, sorry it took me so long but here it is. The dimensions of the room you can find them in a post I made earlier. The dimensions the other 2 drawings, one you can find in the link I posted and the other has 2 gypsum boards on each side of the studs. On one side they are each 1 cm wide and on the other they are each 1.375 cm wide. The studs are 5x 10 cm and are separed by 60 cm. If you have a question please ask. Thanks! Andres

by the way, I was looking at the drawing and apparentely the gypsum boards that are outiside (facing the room) are too narrow and the lines of the drawing are to thick, but there are to gypsum boards there. Thanks, oh, and one more thing, the space were there are no walls, I was planning on putting a window there, but I didn't have time to do it, thanks!

dresso,

You have an OOOPS here, bro...

You are showing;
exterior
concrete block wall
gypsum
gypsum
stud::offset stud
gypsum
gypsum

You will have just created a triple leaf wall...

Try;
Exterior
concrete block
1" air gap
single stud
gypsum
gypsum

Fill the stud wall cavity with insulation.

As an option, add some kind of plywood to the studs before adding the gypsum

Ok, thanks!

hey.... I was wandering if it would be possible for me to seal and use the closet room as the room were I would place the ventilation machine? or is this room too small? thanks.... the closet dimensions are on previous pages...
