Advice for Home Sunroom Studio Reconfig, Sydney

Hi – for some time I have had a home studio set up in a small (3m x 4m approx) enclosed sunroom at the front of our home in Sydney (rough sketch attached of present layout). I am about to reconfigure my layout with the aim to improve my acoustics for mixing. The area in blue is where I am mixing at the moment – the area in red is where I propose to move it to, and the sketch shows approx where I plan to put some acoustic panels. The floors are timber, and the 2 long walls (2.6m and 4.5m) are just stud walls with full-width windows about 1 metre off the floor (the windows are about 1.2m tall). All of the windows are covered in block-out curtains to the floor. Ceiling height is 3.1m (flat gyprock ceiling). There is no acoustic treatment in the room other than double-block out curtains on all windows and doorways, and a heavy woollen rug on the wooden floor, I realise now after reading through the forum that my mix position would be greatly improved bearing in mind the 38% rule, and moving up to the end of the room so the monitors are firing down the longest length. It would also get me away from where I am at the moment which is midway between two walls. I’m just wondering what effect the irregular rear wall would then present me in terms of reflections, and how to treat that area? It comprises a single doorway opening into the room (this has been covered in padded fabric), and then a recessed work area about 1m deep to one side with built in work desk and bookshelves overhead. At this point I am thinking of placing an absorption panel on the exposed brick wall above the door, and getting a free-standing absorption panel (as tall as I can) to place in front of the recessed area. Perhaps also, putting some small panels in the corners where the walls and ceilings meet? The sketch shows roughly what I have in mind. I would also treat the wall to the right of my proposed new mix position, possibly also the wall corners above, with a panel on the ceiling above the mix position. I don’t know if I need to treat the curtain side as well to the left of the mix position, but thought it would make sense to put a matching acoustic panel on that side in any case so as to balance the acoustic treatment either side of my mix position. The wall immediately behind the new mix position has heavy curtains across the full length so I don't feel I will have to treat that as well (but do tell me if I'm wrong about that!) Does this all sound like a reasonable approach? Thanks – Steve Lindsay

i would ignore the front indent when calculating my desk position - i.e. put the desk centered between the side walls rather than then alcove. otherwise you'll be off center in the room and the side wall reflections will impact your imaging more than that corner will (since you want to cover it so its not a diffraction point - which would be a problem). remember to treat the first reflection point overhead with absorption.

Thanks for the advice Glenn, it is appreciated. Steve.
