a dark humming tune constantly same frequenz. I take my time to help you, because the hum gives much stress,...
I wonder ,that much people often hear when begins at about 200 Hz
No wonder they not hear this horrible humm,.... or many men do not hear consciously.
Most people live with their eyes , I with my ears (I think,...)

I always thought it were the hightension electriccables above the earth (100 HZ) but because of your tune-generator i think now,.......

Write it down while you still remember the details. We will look for the others.
If this reminds you of something a friend or a relative told you once and never mentioned again, send them this page. Reading that a stranger described the same thing is usually the part that helps.
