The hum has been off for most of the night, but it just turned on at about 5pm. It's amazingly loud.

It is not acoustic because it is appearing in only my right ear no matter how I turn or where I go in the house (or outside).

I can only guess that it's electromagnetic (HAARP?) and it must be very powerful in order to cause neuro-induction.

If anyone else is hearing a hum, please contact me. Let me know what you've experienced.

I have a friend in the area who also hears it, but not everyone can do so.
