I live in a townhouse that is near a park. There are some days that the park is much louder than usual and once in a blue moon they play some music which has loud bass noise.
I am trying to put mass between the park and my window which faces the patio. I obviously can't post up drywall as this would be ugly and most likely won't be approved by the building HOA. Any ideas of nice designs that I can come up with of building a room in my patio to add mass between the park and my window?
Thanks in advance.
