Retreating into a soundproofed room seems like a dream when noise from loud neighbors or noisy children is too much to bear. Soundproofing a room can be expensive, but there are some ways you can cut the noise without cutting too deeply into your budget.
Things You'll Need
White noise machine
Install a white noise machine or a turn a radio on at low volume. More sound can effectively fight sound. Low-level sounds include things like a white-noise machine, a small waterfall, or even a radio turned way down so that it is very quiet. If combined, all three of these things combine to make a neutral sound in the room.
Caulk all of those small holes around the windows, doors, pipes and floorboards. Just doing this one step and closing all of those small holes with a non-hardening silicone caulking can drastically cut down on noise. Sound waves travel through air. Knowing this one principle is enough to assist in preventing unwanted sounds.
Install storm windows to keep out noise from outside if you don't have double-paned windows. Storm windows utilize the dead-air space between the storm windows and the windowpanes to trap sound. Leave storm windows on all year over windows that are in a high noise area. Be sure to make sure that the edges of the storm windows are sealed and airtight.
Seal the bottom of the door temporarily with a towel if the noise is coming from one specific room and is temporary. For a more permanent solution, try weather stripping around the edges of the door and a sweep at the bottom as well. When neither of these suggestions are successful, try replacing the door with one made out of solid wood.
