room in a room

[bass man]

Hi

Can you post some links or info on how to build a room in a room ? It seems like i am not using the right words for searching .

Thanks

There were several posts on here.
I believe ASC has some examples and I'm sure the johnsayers forum has lots of information.

FWIW, both of my rooms were built that way using Kinetics Noise Control equipment.

Well actually my idea is since my "studio space" is in the basement with concrete floor and regarding to this thread Recording Studio Design :: View topic - Is a Floating Floor Right For You? Answer: Probably NOT.
to float only the walls and the ceiling and to use some neoprene/gum/rubber band etc material between the walls and the concrete floor ....

What do you think about this idea ?

Well my rooms are in my basement. The control room is built up on Auralex U-boats with sand/rockwool cavities. The mastering room is built on a Kinetics KIP system. There are several ways you can go. It just depends on if you want to keep sound from getting out, or getting in from up above.

I want to keep sound from getting out for sure that is why i want to build room in room .I am just trying to make sure that i dont have to spend my money doing things that shouldnt be done and this thread is really a good news if you know what i mean . Did you read it? What do you think of this approach ?

Try doing a search for "two leaf" on the John Sayers forum.

You should definitely understand what a two-leaf system is, and why it is beneficial before you start building.

In addition, I highly, highly recommend Rod Gervais' book, "Home Recording Studio, Build It Like The Pros." He goes into great detail about how to build 2-leaf systems correctly. That will be by far the best $20 investment you can make into your studio.

What is your question? Adding to the excellent advice in the post above, Kinetics was already mentioned, as was ASC (Acoustic Science Corporation). What search engine are you using?

ASC
Kinetics


Here are two more

IAC
Vibro-acoustics

I seem to recall that all of have diagrams/pictures on their websites.

The concrete is not going to be good conductor of energy because it's got the equivalent of thousands of "hands" pressing against it to keep it from "ringing."

If your slab is of good quality and suitable for construction, then you should be able to build on it without much risk of the slab being a significant transmission (flanking) path of structure-borne noise.

Rod Gervais, author of Home Recording Studio: Build it Like the Pros, writes about this in his book.

Rod Gervais wrote:Except for in very weird cases (i.e.: highly hydraulic earths with high water content - OR the inverse of that - both you and a neighbor have your foundations pinned to the same run of bedrock) the amount of transmission you receive in the upper level of the home or outside of the house - is VERY small coming from this slab. It just takes too much energy to move it that much....

It's the airborne sound that transmits through the deck - deck assembly, windows, doors, ducts, pipes, holes, etc., etc., etc. that cause 99% of your problems.

For existing slab on grade I am a firm advocate of leave it alone. (Source)
So, if you're planning to build your studio on concrete that has firm connection with earth, you most likely don't need to float your floor(s)/room(s).

And then once again, my idea was/is to "float" only the walls and the ceiling and to use some neoprene/gum/rubber band etc material between the walls and the concrete floor of the basement....

Any comment on this ???

Well ok here is the the deal . I want to build the studio in the basement and its all concrete ,ceiling,walls and floor .No windows. Looks OK.The concrete floor is new and it does not have a contact to the walls there is some gum material in between the walls and the floor.
I want to build the room in a room without floating the floor .
So the concrete ceiling and walls would be one leaf and the second leaf would be two layers of drywall with 10cm mineral wool or rock wool insulation in between concrete and drywall .
So it is a two leaf system wall .
Since the walls have to meet the concrete floor i was thinking on using neoprene for isolation between the drywalls and the concrete floor .

Is this idea like totally out for you guys ?

Yes it will work. Work out ALL the details before you start. Resilient material thickness and hardness required, bolt isolation devices, anti-sway clips etc.

Good luck!
