Can you hear electrical appliances?
Television sets, not from a mile though (and I heard it a lot better 10 years ago, but I am getting old I guess;-) ), but in the same room I always hear the high sound of the horizintal deflection as well as well as the vertical deflection). Also almost all appliances that have a 50hz transformer build in give a very irritating low vibrating noise. I often put sound damping foam in and/or under these appliances, especially in the sleeping room that is needed to be able to get some sleep. And the worst are some light dimmers, I can not even come near some of those, while other people do not even seem to hear it.
I think that is one of the reasons why I feel so much better when sleeping in a tent on a camping in Switserland (for example). The lack of sound it such a relief, and I get an incredible energy boost then!
