Drum room project
Posted: Fri Jul 10, 2020 1:08 am
Hi everyone
My name is Paulo, and I've found this forum after searching about DIY studio projects, during the pandemic period...
First of all I'd like to say that this type of forums are amazing, because here we can get so much information! So, thank you for that!
Here I've found lots of information about the project that I'm planing: a drum room in my basement to practice and to do some home recordings (if possible), and try to not disturb much my neighbors.
I saw the beeros05 project and it is really an exemple to follow! Great job for him and for the forum!
So, if you allow me, I have a room in the basement of my building, that I've been using to play/practice in the last 15 years, but it is not prepared to play drums comfortably. I need to practice more, so I need to prepare the room to be comfortable and to avoid much noise to my neighbors.
The room is in the cave, where there are garages for the cars, and rooms for storage. My room is 2.91m width, 4.25m length and 3.45 height, it is a 12m2 with 3.45 height. Above the room is my own apartment. The floor of the room is concrete over the earth. There is a window that I'm closing using glass bricks so I can have day light. In this side there is the garden of the building. And on the other 2 sides of the room there are other rooms for storage, no ones use the rooms for any purposes other than storage. Because the rooms are all similar, I have one door that I must keep. It is a very cheap door without any acoustic treatment. And I installed a double glass door in the inside a few years, but at that time I was not considering the soundproofing as I'm doing now, so maybe the door is one of the issues I have to deal with...
During this period of searching I did some tests using the "Decibel X" in my iPad, by suggestion on a group on Facebook. These are the results:
Inside the room 110dB;
outside with door open 103dB;
outside room door closed 76dB;
in the middle of the garage (30m away) 66dB;
outside the garage, window side (30m away) 66dB
above the room, inside my own apartment 61dB
The lowest frequency showed in the iPad is 43Hz. I used a 22" bass drum.
If I could get 60dB of soundproofing I think it will be great for me to practice without disturb my neighbors.
At this point I filled all the cracks and I'm closing the window. And I've been reading many similar examples to follow.
So, my idea for now is:
Create a room in a room type. A friend of mine, architect, told me that I can use a mix between wood and metal studs. The plan is to create a wooden structure to receive the metal studs for the double leaf drywall 15mm thick (fire resistant - 12.4Kg/m2). But here I have one question: The ceiling with 2 layers of drywall will be around 300Kg weight (12.4Kg/m2 X 12m2 = 148Kg one layer of drywall). Using 2 layers it will be 300Kg for the ceiling. It seems very heavy... What thickness to hold 300kg of drywall?
About the existing walls they are brick walls 15mm thick. I've read that I need 10mm+ of distance between the brick walls and the new drywalls. Here's another question: another friend told me to insulate the existing walls and the ceiling using cork boards 30mm. Does the cork have any considerable impact on soundproofing, does it worth it? Or I must go for the drywall structure using the rock wool insulation (60Kg/m3)? If I use only the rock wool insulation, I must fill all the gap 10mm+ with insulation?
About the door I need to create a space for a new door on the new structure, to separate it from the existing inner door. This new door will open to the same side as the existing inner door. So, it has to be larger so I can open both doors to the same side.
About the ceiling I have a big question: I thought not using all the height for the new structure, the room is 3,45 height. I thought about using 2,70m of usable height, so it will create a 750mm gap of space between the existing concrete ceiling and the new drywall ceiling. Should I fill all this space with insulation? Does this make sense? Or it will be acoustically chaotic? Or I must create the room in a room with 3.45m height?.
For the floor, I'm thinking of installing a laminated floor, and a drum riser for the drums.
If you have any suggestions I'll appreciate that.
Thank you very much for your time!
Cheers
