how interesting

I dont hear the hum always, but I know there are times when I am bothered by background noise, often while trying to sleep. I do sometimes even get up to check the source (sounds like a car idling but when I go outside...nada) Being here in Florida I often wondered if it is just the combined drone of multiple air conditioners but I hear it winter too, even when no heating even needed.

I came to the conclusion that it is likely electricity.

I do have super sensitive hearing

lol last night was no hum but as we are having heavy rains after months of drought, it was endless frog songs coming from our stream out back
