Rooms that are not suitable for mixing, but.... need advice

[lsagramour]

hello,

My name is Louis Sagramour and I live in the town of Évreux, France.

I've been following this forum as a guest for some time now. There are many interesting questions that I have seen addressed here with good results. So, finally I decided to put a question here also:

My goal is to make a mixing room from two rooms that I can choose. I understand that none of them is suitable for a mixing room; however, it is all I have....

The first bedroom is in the attic and has a sloped ceiling which is very (very) low (sloped ceiling room).

The second room is a rectangular room but is smaller (rectangular room).
Please see images below or sketchup files (about 4MB) in the links:

It seems to me that the rectangular room is “less bad” to make a mixing room.

I would like to know your opinions and comments on the possibility of using any of these rooms as a mixing room.

Thank you.

PS: sorry for my poor English; in fact is a little of Googlenglish... but I read quite well
PPS: sketchup images have some errors ; I just learned to draw in sketchup two days ago...

anyone?

I would go with the attic room with the sloped ceiling. Still have to do some room treatments to deal with the parallel side walls, but the slanted front wall/ceiling will make it a little easier to deal with. Plus the larger volume (does it have more volume even with the slanted ceiling?) will make it a better mix room.

There is no mention with regard to isolation

The 'attic' area would be a challenge. That post/column would be near the sitting distance.

The rectangular room might be easier to treat ...

More info might be helpful in the decision.

Hi,

Thank you both for your replies.

RJHollins, the walls are concrete and one is drywall, and the floor is wood; besides that, there aren't any isolation.

I did some measurements with REW in the slopped ceiling room untreated (the measurements are at relatively low SPL because it’s around my mixing levels); the monitors are apart from each other 117cm and are spaced 17cm from the rear wall. The images of REW measurements are attached and in the link below are the REW files for both monitors, and left and right monitors:

--left monitor:

I have done a “simulation” of possible acoustic treatment for both rooms but possibly is not enough for the problems in 50-500Hz range (please see attached images of treatment and sketchup files for more detailed views):

--rectangular room:

As RJHollins says, the rectangular room will have more treatment possibilities, but I would like to use the room with slopped ceiling.

Unfortunately the rectangular room is occupied and I can not make measurements; for now I cannot compare both rooms.

Thank you for your comments.
