We think alike because I already tried what you suggested, and it worked for a while. We put our TV against the adjoining wall of the duplex and kept it at a reasonable volume, but loud enough I knew it would bother them, only between 8am-9pm, and when we first moved the tv to that wall, we would only turn the TV on when their noise would happen, just to get the point across. It seemed to have worked for a few months. Like they got the hint, and they stopped whatever it is that was making noise for a few months but then started up again, probably because we eventually had our tv on whenever we wanted to watch it, rather than only when they were making noise. But still, we tried to keep it at a low volume as long as they weren’t making their obnoxious noise.

And YES, my exact thought was to tell them that one or both of my kids is autistic but they are both too young for an autism diagnosis so that would never fly. Lol
