My control room layout

here is my room and my idea how to treat it. I would like to get some comments.

I will record rock, metal, folk bands as well as work with some radio ads and movie scores.

First four sketches represent state as it is now. Last two idea how it could/should be. Probably it is wrong so any advice appreciated.

Walls are 1m solid stone thick. I planned to fit double doors between control and recording room to isolate them acoustically.

Thank you

Here for the gear
 

I don't know that the diffusors on the back wall will do much good if they're that small. Also, some people recommend putting 6" thick traps on the back wall.

Possible things:
- Larger diffusors
- Traps against back wall
- Traps covering floor to wall corners to your left and right (at seated position)
- First reflection coverage on your ceiling

Great looking room all around, in my opinion. Good luck with it!

I think it is a good start, but would recommend a lot more panels in the corners if possible. For the back wall I also agree with kannon19, diffusion is ok but you also need thick absorption.

And what if I put some thick curtains alongside absorbers and diffusors? Would that act as a some sort of absorber for high frequencies or rather diffusor?

You can put curtains in front of the panels but NOT in front of the diffusers. Diffusion is used to diffuse upper mids and high end. The curtain will absorb that.

See the following on diffusion to get a better understanding on how it works.

Thank you for spending your time answering my post. I'll try to post pictures.

some fresh renders. Eliminated early reflections and more bass trapping. Some gear in place.

That's a heck of a drawing. For a bit there I was sure I was looking at a
real room (and was impressed by it).

Just out of curiosity, what kind of building has 1m thick walls ?

Could I ask you 1 more question guys, what is the impact of the shape of my room on acoustics, what I mean here is this 1,2 m high yoke/shelf that goes around the room?

I would cover more of the back wall with thick bass traps. With 1m thick walls you probably have a deep dip caused by back wall reflexion.

Yep. that's right, i will raise monitors, that was first hour when i finished hanging those absorbers and couldnt wait to make some photos. :D
Thanks for the comment on side reflection absorbers. I will try to place them horizontally.
Was listening to some records today (Evidence-Faith No More, Aga Zaryan, Stadium Arcadium -RHCP, Don Giovanni-Mozart, some Gorillaz and Chris Botti Live in Toronto after Sade's - Lovers Live)
I will make few tests tomorrow morning and will bring some results home :D.
Have to say that what I can hear is: bass is very short, what I mean disappears quickly (I presume thats good) i can hear maybe two slightly louder notes when i play bass in lower range. Mid and high: room sounds bright and clear with no flutter echo effects,still it's nothing like a dead room that i've used to work in before - new room sound much nicer, hard to describe that but i'll try too. In my old room it felt like you had a bad day on and on: tired, dull. New room sound like a sunny day on the beach, you feel fresh, have mojito in ur right hand and your left hand stays put on your girlfriends .......Porsche keys :D!!!
Now I can understand that when someone is asking how to spend 3000$ experienced fellas say: spend the whole lot on room treatment.

Your ceiling (looks to be made from OSB sheets ?) is curved in a way that
is opposite to how a poly is normally installed. The way yours are would
concentrate sound in specific spots instead of dispersing it.

it is a brick ceiling. You r right, that is why i installed a foam cloud above listening spot.

measurements results. I think its not that bad. there was a deeper dip around 95 Hz that i solved placing absorber behind the monitor which gained 5 dB from the front wall reflection effect (i think so) Dont really understand dips around 1050Hz and 6500Hz. :(

I'm not trying to start an argument, but you're saying those arches are made
out of brick ? Why ? Or are the arches sheets of absorbant ? In one of the
pictures it looks like you can see between the arch and the ceiling.

no problem, me either :D (its just im not living in english speaking country anymore so if i offended you i;m really sorry, my english is getting worse and worse with every week now :/) just trying to get some advice from more experienced ppl. actually ceiling is made out of bricks, it is basement in very old building, thats the way it was built. brick is empty inside if you know what i mean:

http://www.dachbud.com.pl/galeria/cegly/dziurawka.jpg

i know those arches act like a satellite dish a bit, concentrating waves in one line but as I wrote before you can not hear this under the foam cloud which is my listening spot. If I could change that I would but it has to be like this for now:/

Please someone could comment on my test results?

Oh, I just noticed I'd already pestered you about your building - you're the
one with the 1m thick walls. I'm sorry I can't help you with your room, I'm
just fascinated by its construction. You'd have to go down into something
like the New York sewer system to see something like that on my side of the
Atlantic.

Just a bit of off-subject curiosity, sorry to butt into your thread.

No Problem Paul, you are very welcome to ask any question you want, and that;s how the building looks fro the outside:

The response looks pretty good to me. Those aren't huge dips, most of
the plot looks to be within +/- 5db. Can you generate a waterfall plot ?

Have you tried moving the microphone very slightly forward and backward
to see what effect that has on the response ?
