Studio room slat wall, CR redesigned

I have placed hangers on the ceiling of my Studio room, as recomended in this thread: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3585 I'm currently building a wooden structure below the hangers, to have an absorptive sloped ceiling. One of the joists is about 30 cms apart from the wall. The object of this is to attach a slat resonator structure allong this entire wall. As proposed in the SAE site, but the larger portion of the wall will be on the ceiling, and the 10 cms part will be at floor level. This because I don't want to loose too much space at floor level. My question is: once I have the slat resonator wall, should I put bass traps/broadband absorption on each corner? Even though the entire ceiling is filled with hangers (about 34 of them) Or am I better off leaving just the sloped wall and a couple of corner traps on the opposite wall? The idea of the slat resonator wall is to minimize standing waves/flutter produced between parallel walls only 1.62 meters apart! I'll attach my designs and some pictures as well. Thanks for any input! Rodrigo

I'll be putting on hold the treatment for the CR. I need to decide about the Studio room first, so I can lay down the floated floor and treatments, a laminate floor on both rooms and then start with the CR. Ok, now the plans:

Ok, my file comments didn't show. First you have a picture of the current hangers on the studio room's ceiling. The wall you see will have a large wooden diffuser. Then you have a side view of the plans for the Studio room. Corner absorbers won't cover the area from floor to ceiling. This is because I need the space to fit furniture (amp and misc. storage), a bulky electric piano, etc. Instead I'll simply attach fiberglass and cover it with fabric on the lower areas. Last there's a top view of the studio. The dotted lines represent the lower area of the corners I was talking about. The 30 cms from the concrete wall to the slat resonator is only representative of the highest point. The sloped wall will be about 10 cms from the concrete wall at foot level

Now, these pictures... The first one will give a better sense of space. You can see the entrance door, the door between CR and live room, and the WC's door. Next picture shows the opposite wall to the slat resonator wall-to-be. You can see the column and the higher part of the sloped ceiling. Now the plans for the CR. I need advise on how to treat it properly, again leaving the lower area of the room as unobtrused as possible.(sorry if this word doesn't exist)

This is the last one. Sorry if it's too many pictures. I want to be as clear as possible. This picture shows the rear wall of the CR. My idea is to have a sloped absorptive ceiling coming from as low as the doors' height onto the original ceiling covering about 30% of the room's ceiling. The rest will be sloped the opposite way; from the front wall onto this point. The other big problem here is the space... I'd like to put some kind of bass trapping in the guitar closet (it's on the right with a desk crammed in). I'd like to have a couch cornered to the right, but this will leave no room for bass trapping on the lower area, so heavy traps will be in order. I'll build a two sectioned door so I'm able to open the guitar closet without moving the couch.. What do you think? is this pushing it too far? Well, anyways... thanks for any help on how to treat this area... Rodrigo

Thanks! Succinctly; Andre

Rodrigo, why don't you knock out a door from the computer room to the amp room so you only need one door on your back wall. cheers john

John, thanks for the reply! That's a good idea that I hadn't thought of. However, if I'm able to use the current configuration and not affect acoustics in a negative way, I'd like to stick to that. The problem is that the computer room is also a restroom, so I have the sink crammed into that small space, and if I knock out a door in there, the small area would be comparable to the original plan. Maybe if I build a brick wall on the right corner; reducing the width of the guitar closet's door. And if I use a solid wood door in there, I wouldn't have as much sound going through...almost like a wall What do you think?

Any comments on the acoustic treatment design? Specifically the slat wall and its corners Many thanks! Rodrigo
