Sealing a Door to Make It Soundproof (Regardless of the Damage to the Door)
There are two doors in my room. The second door is between my room and the room of the other person. It is never used and is always closed. But there is noise coming from the other room. Can you explain how I can insulate the door to make it as soundproof as possible? Since the door will be removed and replaced with a wall at some later time, any temporary measures can be taken now regardless of the damage to the door. I need to find out what method works best in terms of reducing noise.
