If it’s too noisy at home, try these sound-deadening ideas from unplggd.com, “especially when your neighbor sings like a cat in heat” and you can’t cover your walls in foam:
1. Whenever air gets in, noise gets in. Make sure windows and doors are sealed and weather-stripped.
2. Everyone knows that curtains and fabric wall hangings cut down on sound, but don’t rule out rearranging the furniture. If a shared wall or a wall facing the street is noisy, consider placing a big upholstered couch there to absorb sound.
3. Rug are great sound mufflers. The plusher or shaggier they are, the better. And area rugs on top of carpeting work better still.
