1)Is it possible that local security systems can affect electrics? I live in a link detached property with a neighbour to my side, one to the back, about 50ft away, and one across the road 50ft away, all with security systems. How far could their range be?

 

alarms wifi ect.. won't transmit enough power to effect you,

 

weird noises will be from industry or a sub station, pylon  ect...

 

or your going "strange"

I can hear the high frequency of some TV's , I can hear my fridge and my freezer,

 

my hearings been knacked 8 month,

 

head cold, then ruptured eardrum, had antibiotics  at the time

 

need to see a gp then a hearing specialist, being very busy & the gp being unfit for purpose means I'm screwed

I can hear pylons and all sorts of stuff if Im close enough, I have to concentrate to hear it as my brain blocks it out.  Its like when you put your sunglasses on for a second or so everything goes red then your brain says, "Thats not right everything isnt red" and then everything goes back to normal but without the pesky sun in your eyes. Assuming you have red sunglasses that is

I had the exact same story before Covid, ENT can't find anything but regularly got tinnitus which to me is a "hum", the more you think about it the more it comes back.

After several years of this I can say you seem to just block it out most of the time. The more you worry about it the more you can trigger it.
