I was living quite happily with my apartment HT going at full volume until a new neighbor moved in across the hall. Unlike the young couple who lived there previously, the new neighbors are complaining about the noise. My building is superb when it comes to noise transmission. Shared walls and ceilings transfer almost no noise at all, even at high volumes. However, when they renovated the building they got cheap when it came to the doors. While the neighbor I share a wall with (who also happens to be the super) hears nothing when I watch a movie, the people across the hall are bothered because the noise travels from my doorway straight to theirs. I'd like to build something to put in front of or inside my doorway to minimize the amount of noise coming from my door. Here's a couple pics of my doorway: http://www.codebloat.com/junk/doorway.jpg http://www.codebloat.com/junk/doorway2.jpg As you can see from the pics, the doorway is recessed into the wall by a little over 7 inches. I'm thinking that I could build something to stick into the doorway, maybe something made of acoustic foam, plastic, whatever. Something that I could easily put into place when watching a movie and then remove when I'm done. Any ideas?
