Iso booth/room on the 1 floor, woodden floor :(

Hello !! I have searched through the forum and I couldn't find any answer to my problem. The problem is that I have to build my studio on the first floor. The floor have a wooden construction (the building is very old). I need to build just a drum booth. What can I do to reduce sound transmission through the floor? I can't make a regular floating floor because the old floor will collapse for shure. I thought I could build another wooden floor attached to my walls with something elastic and then build a room on it. Is it possible ? Have anybody do something similiar ? Will it work efficient enough ? The room is very high, more than 3 meters. So vertical space is not a problem. Moving to another space is not an option. The room dimensions are: width 5 m, length 5 m, height 3 m I need just a small drum room inside of it about 2 m x 3 m would be enough for me.

I am more than certain that if you think about this for a while, you will indeed find the answer you are looking for, here on the RSD forum. Distill your actual question into smaller, more detailed problems and work your way through the different posts. Use the search function for each of the basic problems in regards to your project.

I am uncertain if there is such a thing as a "regular" floating floor. Do some more research and if you run into specific questions - make a new post with them. I am sure that if you direct specific and well formulated questions, you will get answers accordingly. /Gash

ok !! I just want to know if there is any way to build room within room on a wooden floor ?? By wooden floor I mean wooden construction of the floor on witch or above witch the room will be built.

I can not see any reason as to why this would not be possible, given that the floor supporting your drum booth can withstand the added load. I believe a more detailed calculation is required to give you a more precise answer. /Gash

No it can not withstand the added mass :( If it would than I wouldn't waste your breath ....

Hi, have you tried to find a structural engineer to check if your existing floor can take the additional weight? Even though the building may be old it is possible that the existing floor joist may be able to take the additional weight, but it would be essential to have this checked by a professional, a booth with 2 layers of plasterboard on each wall and ceiling can weigh over a ton. Perhaps if you post a few pictures of the room and a rough plan of what you would like to build someone here might be able to offer you an alternative solution. Have you access to the room below where you intend to build? If so you may be able to reinforce the existing floor joists to allow the additional weight to be carried, again the advice of a qualified structural engineer would be essential in determining you options. Good luck, Clunk

Here we go !! Current floor is not able to take the mass for shure !!! I can't modify nothing below. If it would be possible I would make solid floor and wouldn't be wasting your time. That is why I am asking about the possibility to build another floor very low attached to the walls with some kind of shocks or something else absorbing the structure born noise. What I am trying to build is a drum booth as much sound proof as possible. I can't develop any plan cause I don't really know the possibilities and that is the answer witch I am looking for !!! I will post pictures and some kind of drawing in the evening. I apriecieate your current posts, maybe I have a communication problem because english isn't my native language ?

Hello again, I understand what you are saying and asking but in my opinion no-one can give the advice you are seeking based on what you have posted here. It is also unlikely that even with further information that anyone could advise you properly across the internet. You need a structural engineer to look at your situation and provide a solution for your particular needs. It may cost a little to get this done but it will be worth it, you never know what they might recommend. All the best, Clunk

I have been talking with few guys, and the second floor built above the existing is their idea. I just want to know what you guys here think about this. Have anybody done something like this ? How much noise transmission through floor can I expect with such a construction ? Would it be comparable to solid floor with a floating floor or maybe even better ? If someone made something similiar, what should I use to join the new floor with walls in elastic way ? Should I make the new floor in some specific way ? I know that a lot of great people are here, and that they worked in a lots of recording studios etc. So I thought maybe they came upon something similiar somewhere ? Am I the only person who is trying to build a drum booth on the first floor of a very old building ? Enginiers in Poland know a lots about building but they don't know nothing about the acoustics. In their opinion I should use thick carpet :) and some "acoustic" foam that is why I am asking you. I know the basics and I understand that this is complex situation but I belive there are some wise guys who can tell me something what I should know before I start to build this second floor. Maybe the idea is stupid I don't know. I also suppose that it is a common problem while building recording studio or rehersal room in an old building so if we could just work out some great solution lots of guys could reuse it. I've read similiar questions even on this forum left without an answer. It is really easy to say: Maybe your floor will withstand .. Maybe you should ask somebody... Maybe it is impossible... Common can't the pros find the solution or just tell me that I am wrong or right ?

One simple issue is that that you are still connecting the new floor to the same wall. Flanking will still dominate. Andre

Take a look at this link boss: http://www.johnlsayers.com/phpBB2/viewt ... 24&start=0 Look for gullfo's drum riser in Sketchup's 3D Warehouse...

I have got a permission to reinforce current floor so I will propably build regular floating floor/room (told my neighbours that they will have new celling :D). I have searched through forum and couldn't find something more about the neoprene pads. Where can I get them ? Maybe there are some better substitutes ? How thick they should be ? Should I calculate their size somehow according to mass of my room ? Sorry about my grammar and spelling :(
