Hello all,
In regards to the control room window.... if the distance between the 2 frames (Vocal booth and Control Room) is more than 2' is it still nesesary to angle the glass windows.
Cheers,
Luis.

Hey Luis - I'd think it's probably MORE necessary then - the first harmonic between two parallel surfaces 24" apart is 282.5 hZ, which would definitely be an audible coloration.
There is some debate as to the necessity of splaying for NARROWER distances, based on the tradeoff of too small air space for good isolation. John and F. Alton Everest say splay, even for narrow spaces (John, don't let me put words in your mouth, I think that's what you said) but Richard Schrag (worked for Russ Berger Design Group at one time) disagrees - check this -

Also, just found this last night, might be useful to you at this time - Eric is the resident acoustician at studiotips.com BBS, he's Dutch and I sometimes have a hard time understanding what he's trying to say -

Hope that helped some... Steve

I'd angle them Luis maily for the light factor and creating an angular reflection from them.
Steve - what Eric didn't mention is that a large sheet of glass free standing like in a window is also a large resonator. The drywall is secured to the wall frame at 18" spacing typically whereas the glass is free standing and will resonate back into the room - so the thicker the lower the resonate frequency. I wonder whether his 4" glass used in Galaxy was a laminate??
cheers

If the stories are true about 100 dB separation between any two rooms, I'd pretty much guarantee the glass is a laminate, and with flexible glue at that :=)
Mr. Schrag did mention the light thing in his comments about angled glass - claimed proper lighting design could overcome it... Steve
