I too hear this ringing....buzzing. As previously posted, when I start turning off and unpluging items it's an instant relaxtion. My husband claims
he can't hear it. To me it seems so loud, sometimes causing a headache.
It's difficult to explain this type of ringing. It's different then how your hearing is after attending a loud concert.
I live less then 2 blocks from a couple of radio towers. =( On further thought, it seems like this phenomonon has manifested in the last eight
years while I've been living here. I don't have a recollection of whining about it before then. Also, I'm way older then 20 - physically anyway.
Lastly, I don't claim to have any special hearing abilities, far from it. It does seem my range may be different then most others. I can be in a
crowded resturant and not be able to hear the person speaking across from me but, I can tell you what music is lightly playing in the background.
