In my case although I have a hole at my port (no port glass) the way the hush box is constructed is sound proofed (but is it?)
Dunno what is best and how it affects audio.
In my case, that 3mm glass helps with high frequencies (e.g. amp fans, PJ fan, slight hum from isolation transformer) that I might hear in the theater... but the equipment room is part of that theater room proper ‘fish tank’ as the equipment room is also decoupled and using a heavy acoustical door. So, the dynamic sounds and bass, etc that push through that port glass is corralled and contained in the equipment room.
Goodbye to a great audio and video genius and writer... JOHN GANNON. I enjoyed your friendship, wit and a nice long run we took around Indianapolis at CEDIA years back... and for buying my Runco 980 Ultra years back... you saved my ass! Rest in peace.
