Side wall window

aleatoric · 2nd February 2012

I just checked out a new spot for my studio. The room is great, good rectangular dimensions, solid construction for isolation, perfect location, etc.

The only real issue I have is that there are two windows on what would be my left side wall. The one window is well behind the listening position so I am less concerned with it. However the window towards the front of the room is in the area of a first reflection point.

What are my solutions here? I do not need access to the window and the landlord is cool with me doing some construction in the place. I'd like that side wall to behave as similar to the other side wall as humanly possible.

Would screwing some MDF over it (maybe 2 pieces with green glue sandwiched between?) and then putting a 2x4 4" 703 trap or two over it be a viable solution?

Any input is appreciated.

Thanks.

I guess I could just do a floor to ceiling bass trap('s) right over the thing right?

Makes sense to me to maybe screw a piece of MDF (possibly 2 layers sandwiched with green glue) over it so it behaves more like a wall with a bass trap's over it and less like a window with bass traps over it.

Thoughts?

Worth noting isolation is not the issue. Just acoustics..

Can you just yank it out and frame it up? I'd be hesitant to cover it with something permanently because if a leak/crack/broken window somehow came about, you might not know about it until it does damage and/or you'd have to tear out/re-do your treatments.

Not entirely sure what you mean by "yank it out and frame it up". Care to expand?

If the window cracked I'd know from viewing from the outside. Also the MDF would not be that permanent. My plan (unless anyone has some other thoughts) would be to simply screw a piece or two of MDF over the window and then put trapping over it (floor to ceiling) like I would a wall. I could always unscrew the MDF if an issue arose related to window breakage.

Your solution is better than nothing, but if the window is set in, i.e. has an encasement, sill or whatever (on the inside), I would recommend making a proper plug with a wood frame and MDF or Gyproc on both sides, filled with insulation and sealed around the perimeter, and possibly with gasket where it butts the actual widow frame.

Here is the plan. I'll use R19 for insulation. Once the plug is in that wall will be treated like the other wall with broadband bass trapping. Cool?

OK, but I would add another couple layers of MDF directly over the glass frames (and seal them) so the insulation is sandwiched (not compressed however!) between. This should give you a higher degree of isolation through the window.
