O that's interesting. I was able to do the same (tv, refrigerator, etc). I also lived country side and I have hearing loss (35db) and tinnitus (sometimes? moderate?) in my left ear, but seemingly due to a virus infection.
I have never encountered someone else that was able to hear whether a tv was on or not. At what distance could you do that?
- detritus 4y agoAt least within the house - we moved around a lot, but I lived in a few three storey stonework houses, and could generally tell from 'the other end' of the house if the TV was on. I don't recall hearing the same noise from fridges though!
- aaaaaaaaaaab 4y agoIt only works with CRT TVs though. It's a 15khz tone, due to magnetostriction in the flyback transformer: https://en.wikipedia.org/wiki/Flyback_transformer https://en.wikipedia.org/wiki/Flyback_transformer
- kaybe 4y agoSome of them used to make noise. Ours stopped for a while when you gave it a whack from above.
- ddingus 4y agoI can hear whether they were on or off, and whether they were tuned to a signal or not. A video signal synchronized up has a very distinct profile, and people who can hear about 15 khz can hear the sync signals modulating the higher frequency component. I could at one point, adjust horizontal and vertical hold to a stable signal eyes closed. Some sets were very loud, and I could hear them rooms away. Walking The Halls in my primary school, I could walk by the classrooms and say they have a TV on oh, and nail it a hundred percent every time.
