Small studio design in france

[alex95250]

Hello Every one, my name is Alex, i have 26 years old and i live in france (i apologize in advance for my bad english).

I study in SAE paris and for my memory of the last year i decide to make the acoustic of my studio (measurment, calcul, design and construction).
I read lot of topics on this website but i don't find a response of many question i wondering, i hope you will help me to find these response.

So this is my project:

I have 3 room in my studio:

-a small control room
-a recording room of 20m2
-a room with sofa and WC

I need help to design the control room.
for the front and the 2 angle wall i decide to design slot resonator, i think is good because i will can move the slot after the measurment.
for the celling i will made an angle slot resonator ceiling or instal panel absorber to avoid the early reflection. (the ceiling is 2m height).
For the side wall i don't know what i can do, in first i wanted to instal angle wall slot resonator but the widht of the room is very small (2m widht),also i don't know how i can calculate the minimum angle of the side wall to avoid first reflection on the sweet spot.
For the rear wall i will instal slot resonator or diffuser.

So my 1st question is how i can calculate the minium angle for the side wall and the ceiling to avoid the 1st reflection in the sweet spot.

Also, i want to have a windows between the control room and the record room (on the left side) but the acoustic will be compromise with a windows, especially in a very small control room, so do you think it will be a good idea? actually i just have a talkback between the 2 room and it does the job, but a window is very practical.
The 2nd solution i thought is to install two webcam with screen to communicate.

For the side wall i thought juste fiberglass with cloth and panel absorber on the 1st reflction point (with mirror method) but i'm afraid to absorb too much high frequency.

Additional information:

For the moment is a concret floor, due to the height i can't make an absorber floor, i read some post in this forum and apparently carpet is not a good solution (i don't know why) so i will make a late floor.

My speaker is yamaha hs50m, the event is on the rear, that's why i don't made a soffit mounted.

The desk won't have foot, he is support directly by the wall.

I tried to respect the rule of 38%, for the room dimension, in some case i can't respect a good ratio so i must do with this.

I was inspired of some studio container like spark1 and other because i have almost the same dimensions (except the longer).

thank you in advance for your reply.

After read a post about the 38% i think i made a mistake, i design the sweet spot at 38% of the front concret wall and not at the front slate resonator wall, can you tell me if its correct please?

Hi. Please read the forum rules for posting (click here). You seem to be missing a couple of things!
