Need advice on dealing with a thin wall between my neighbor's living room and my bedroom. He leaves the TV on all day because he claims he is hard of hearing, but it sensitive enough to hear when my radio is on and raises his volume more.
I can hear his TV at all hours and usually turns the volume down at midnight, but I can still hear mumbling from his TV.
The issue is the thin wall and I am open to suggestions. After some Google searching they say that a thick rug or curtain on the wall won't do anything and the only way is to open the wall and install sound insulation or put up new dry wall over the original wall.
Has anyone had luck with thick curtains or putting up a rug over the wall? Or something else that doesn't require tearing walls down?
Open to any other suggestions as I don't like having the TV or radio on in my bedroom.
