I run a comedy club in a room upstairs from a bar. There is loud music coming from the bar, and it travels out the open door way, upstairs, and can be heard through a closed door in my room. There is another door on the other side we use to allow people in, so I was hoping to somehow block sound from entering in the doorway.
What would be the best way to stop that sound? I've tried to put some carpet etc in the gaps in the door, but to no avail.
