Acoustic treatment for side glass doors / please, need ideas.

Sadly, wife's home renovations forces me to move my audio system from the family room (not the best place anyway) to a small room but with side glass doors (sadly yes, BOTH sides). Room is small, 15"(L) x 10"(W) x 9"(H) . I was considering install drapes (maybe better, roller shades) because in that area cant have fixed solutions. I really need some advice here because this change can ruin my relax moments listening my records and having a glass of scotch.
Thanks in advance

The problem is a lot worse than people suspect as windows vibrate, walls vibrate, and there are a whole bunch of sound pressure peaks distributed around the room including room corners and the 3D space of the room. Room acoustics requires an in depth analysis and a multi pronged attack. If it was easy everybody could do it.

Just a reminder - there are (at least) three issues for windows and sliding glass doors. One is reflections, the second is the vibration of the glass produced by acoustic waves. Therefore, multiple methods must be employed. The third issue is RFI/EMI for which glass is transparent.  RF enters freely from the great outdoors or, in the case of interior glass doors, from adjacent rooms.

I would be remiss if I didn’t put a plug in for crystals, which can be quite effective in dealing with vibration of glass doors and windows.

I’m positive you don’t, Tom.

Tom, I'd like to help you out. I really would. But if I told you I'd have to kill you.

"You might want to look at groffkait’s website, he sells very small adhesive copper strips, that tune the glass, highly effective & inexpensive, work well with pretty window treatments."

The 1" copper Flying Saucers for windows (1 per window) and sliding glass doors are not dampers or tuning devices. Flying Saucers for Unused Wall Outlets which are copper on plastic inserts are their companion product. Both products should be placed in ALL rooms of the house.
