HELP Question about acoutsic treatment.

Hi John and all of you, In the studio I'm building and designing I have a window to the right of the mix position, see drawing. How should I treat the wall that's the opposite of that window. Should I put diffusers there or absorbers....or something else. I'm think that there must be acoustical symmetry at the mix position, but how can I achieve this? John or somebody else, could you give me advise about this? Thanks, Michel

If you want retain symmetry, then you could hang a large picture or poster with glass over it, the exact same size and shape as the window, and exactly opposite the window, on that other wall. - Stuart -

Thanks Stuart. Maybe that's a possibility, but what about the reflections on the sweet spot? The window ,is placed under an angle so maybe I should do that with the picture as wel.

Symmetry is not the word. you WANT it different concerning acoustic absorbers. Just put an aborbing panel opposite of the window on the wall. (you know: soft vs reflection, just like hardfloor, softceiling) But in RFZ we take it a bit further; If the window is a first reflection point, then your design is flawed to start with. to fix that you might wanna put a portable absorber in front of the window.

Or turn the desk to (gasp) face the window.

Ro: The room was build before I came in. If I was asked before they build the room. It would be totally different. The window is indeed in the first reflection zone. So maybe a portable diffuser would be the solution. When mixing they can put it in front of the window. It's not a nice cosmetic solution but it's a start. xspace: That's not an option, in the back there are bass traps and a diffuser and I'm not building them again :) The room would then be very a-symmetrical also.To the left 1.5 meters to the right 7 meters! John: can you shine a light on this? I would appreciate your help...HELP......

No, an absorber ;) Cosmetically it CAN be great. Use it only during mixing (and maybe soundchecking) stage. Put an absorber on wheels to make it nice and portable if you like. you gotta deal with what you got, better make is work then.

Eeeh yes...a portable absorber...that's what I mend according to your advice. I'm kind of diffused here :lol: I must create a view absorber points in the room to get the RFZ right. I think I need diffusion also. I not want the room to be sounding 'dead'. That's why I put the big broadband diffuser in the back. But then again the RT60 must also be low. I still see some challenge here :?

Put a low-end filter on your basstraps if possible, that'll keep the room from sounding too "dead". the other absorbers can be hung on the walls facing the bare wall on the opposite (soft vs hard). Same goes for the ceiling, esp. at RFZ position. A cloud above your mix station/chair would do. If you measure you room, before and after treatment, you'll know what to look for next. If the room's too dead (according to your ears), you can always add a filter in front of any absorbing panel afterward. Keep on posting (don't forget the pix) Ro

Thanks Ro, you're a great help! I love those Fries Guys. I'm a Tukker myself :shock: Polite Bump to John: Do you have any solutions for the problem as described above? Ro's solutions are fine but just in case.
