Our TV has seperate remote controls for the TV and for the cable; if you turn the cable off, the TV will go black and devoid of relevant noise, but it will still be technically on. And emitting the most awful, irritating, grating high-frequency screech. That nobody in my house other than me can discern. So, while I stress the importance of turning the TV off, they have no real reason to remember to, because they don’t hear the squeal of Satan every time they forget.
Is anyone else aware of and sensitive to this noise? Am I crazy?
