I think a good part here is that where I live it is very quiet. Last house on a dead end street, nothing but fields around me for miles and miles. So when it's quiet it is really quiet, so quiet that sounds that you'd otherwise never even notice become audible because your brain just keeps cranking up the gain.

I can hear the dear foraging around the house at night, and if a car passes on the nearest highway (a few kilometers away) I can hear that clearly too. But during the day all those sounds vanish, masked by the ever present background noise level which is far higher than it is during the night. And my hearing is actually not nearly as good as it used to be.

One simple solution I've found is to play really low volume white noise, that seems to instantly drown out all of it but strangely enough is very hard to detect by itself.

I never noticed any 'sensitivity to electronics'.

Interesting. Yeah, it's strange that I never seemed to notice the low hum until, say, 5-6 years ago. I assumed it was the house in which I was living at the time, but we moved and I continued to notice it. In my case, both areas are kind of your "standard" suburb and not too far away from one another. BTW, I've also wondered if it was from some far-off industrial source.

But, I also know we lose our high-frequency hearing as we age. I wonder if that somehow increases our sensitivity to the low frequency range.

In any case, I'll have to try the white noise. Seems like it could help with sleep quality, which might in turn reduce sensitivity to it.

Good luck, let me know how it works out if you want, [email protected].

Thanks!
