Minimal things I can do to soundproof a garage door?
Now, before everyone gets up in arms here, I just want to see if this is at all possible. We have a 2-car, tilt-up, 1-piece wooden garage door. The big problem is that it does NOT close anywhere near to air-tight currently. There are gaps on the top, sides, and bottom. It is an old door so it has warped considerably, which does not help at all. Am I doomed to build a wall instead of trying to make the actual door soundproof? It would be a big pain to cover the garage door in terms of moving equipment and just dismantling the existing garage mechanisms. I'm wondering if there's something that we can put up that will retain the garage door's mobility... some sort of walls we can move? And won't interfere with the hardware SOMEhow?
For some idea of how soundproof is soundproof enough, we've had full-band practices in my bedroom (which is right next to the garage), which has a 1-paned glass window, multiple times, with no complaints at all.. Which makes me think that the garage will be fine bar the door. If anyone has any ideas for soundproofing the thing, please let me know!
