the point is, this woman isn't going to spend hundreds of dollars on ceiling treatment or sound canceling devices. That's why PedalWench and I both suggested the earplugs + white noise device. She probably already owns a fan in her home, the only outlay would be the earplugs. I don't know about you guys, but I've found people in their 80's to generally be VERY tight fisted with money, for good reasons, they're living on teensy pensions and they can remember when you could feed a family with a dollar, etc, etc, etc. So fancy wall treatments are not going to happen. I hope she does call the police, although it sounds like she already has. OP let us know what happens, we're all curious now.
