Realistically, you have 2 options.

- You can build a box around the valve out of MDF and decouple that to provide the mass behind it. Not great but better than a hole.

- You can move the valve in the line down into another portion of the house that's not in the room.

Well, realistically, if you have more than a 1 story home, you already likely have water lines behind drywall in the ceiling. Also, you most certainly have pipes behind drywall walls.

The only thing I'd be concerned about is having access to the shutoff. If you're going to have a plumber come out, just have him move the shutoff to a different part of the basement that's outside the room.

You can always make a 'plug' for a window that slides in place for full light and sound control yet be easily removable with a couple of wing nuts or half-turn latches. This keeps the safety aspect in place.
