First of all i would like to thank you for all the help you give me and many others on studio building. You have been a great help and have supplied all of us with great links and resources to our questions on building our studios. When i get clients in the studio, they always ask me how i know all the stuff about the acoustics and how i know what to build. I always tell them that there is a good guy named John Sayers that is complete genious at it, that always is helping people like me on extreme hard stuff like this.

Its time i need help with my studio acoustics. I have been studying acoustics the last couple of months and have read on alot. I understand the basics and stuff but i still do not trust myself knowing the advanced stuff. From what i have read, your DIY Wall Units sound the most efficient for me. But im afraid if i try and costumize them myself for my studio and conditions, i will do them wrong. Its why i dont even dare attempt yet at figuring them out myself. I am also very slow on construction side. I do not always understand what those blueprints are saying or know anything at all what you are talking about. I just hope that you can help me get through these tough decisions on what is needed for my acoustics, and bare with me on helping me with construction. Hopefully i know enough that we can at least communicate without having to go into extreme details of why this or that needs to be done.

First of all, my studio is two rooms. The console room is about 10x15 ft. The recording room is about 15x15 ft. These are not perfect measurements but close. The walls are all parellel to each other. I need to have carpet on the floor because the concrete underneath is cheaped and not very level. Because of this i know that i need resonators on the cieling to help fix the imbalance caused by the carpet. The wall inbetween is a double wall with a windows in between. The glass is double paned, and there are 2, and angled like shown at SAE college. The main thing that is needed for sound proofing is the ceiling. The upstairs is very lightly carpeted and has not but a 2" wood board as the floor supported by the beams. The joists can be squeaky from footsteps along with the thuds of walking feet. Im anticipating that this will be the more expensive part to fix. I am planning on using fiberglass insulation in between the joists, and putting a flexible channel in between the joists and the gypsum board. Later, when i have the money, i will double or maybe triple the layer of gypsum board to help with the sound proofing. The north and east walls are heavy thick concrete, which generally have no problem with sound proofing, although i was planning on putting a gypsum wall over the top of them both in the future. The south and west wall are newly built walls made of gypsum. The south wall has the window in it and is a double staggered studded wall.
The console room is all gypsum but the east wall which is also concrete. The window is of course on the north wall of this room.

Please, help me figure out where, what kind, the depth of slats, etc, etc that i need to control the acoustics. I will do as much of my part as i can. If you are busy and cannot help me much, that is also fine, any help or suggestions will really be of much help. I know i will need to find the problem frequencies in the room with a tone generator and a reference mic and stuff, and i know how to do that. So if there is any info you need me to find. Let me know. If im starting too broad here, let me know.

Thanks a ton.

Also, anyone elses comments are also welcome. I really wonna do this right but stay in a good budget.

John. Im almost done with the plastering on the walls. I hope i havnt done anything already that will have negative impact on the room. I am planning on painting the room but i was also going to drape the room with a dark blue fabric to help set a mood. The fabric is really thin so i didnt think it would alter the sound enough to make a difference (cheap bedsheets). What do you think?

I mainly need help on making those diffuser boxes and stuff and how thick i need to make them and how tall and where to put them and stuff. I also need a little help with the ceilling on sound proofing and acoustics. Would it help to have a wood pad on one side of the room or something for drums and stuff? I want to take care of the recording room first and do a little of the mixing/console room because my budgets are low at the moment. Let me know whenever your ready.

Btw, dont feel extremely obligated in helping every little detail or anything. Help as much as you can. I meant to sound serious just because i dont want to do anything wrong so as much help as you can give would be much appreciated.

Thanks,

Danny
 
First - have I got the dimensions correct??

cheers

Sorry to intrude but, Hey it looks just like my garage studio. Exact dimensions even. I would like to be included in any advice on this project if that is ok. Would no doubt help me alot too.
 
Cool John. Ill get all the dimensions. The ceiling slopes down i think about 2 inches. Do you want me to include all that stuff too? I will give you as much detail as i can get. I will begin a layout of everything tomorrow and post it up for yah. Thanks again John.

Hangdawg - That would be fine. I want this to be a good informational post for everyone, thats part of my intentions. Maybe you will have some good ideas to share also.

Thanks again.

Danny
 
This is the best layout i can give you of the studio because i dont know how to use cad stuff very well.

This is pretty accurate although it might not be right on the cm :). The ceiling is 7 1/2 ft tall. If theres more info you need, let me know.

I also though i would include what i have for acoustics right now becuase it might work well with what you have in mind. Ive got 3 4x7ft 2" foam pannels that are right now portable. If you think it would be good to cut these up or something and use them for different things let me know. But if not i could use them for onlocation work.

Thanks again John.
