Well, since you said you aren’t worried about forced entry, what about a symmetrical split, self closing, double acting door (opens both ways)? You get the sound-blocking benefits, you can set up something to hold the door open if needed, and you can use the door from either direction with both hands full.
ETA: Or you could have a bifold door that opens by folding in the center (this solution uses a linear track on the ceiling). Looks like you might have enough room on the right.
