Once we were driving a rivet that was through three plies of iron and three of us were pushing on the rivet driver. It was so loud that I actually felt as if I had needles being stuck in my ears for a few seconds before the rivet finally let go. No ear protection in those days. After all, we were ironworkers.
So I was home on the second floor of a two story house. I heard birds chirping and thought I would telephone the landlord and tell him that birds must have infiltrated the attic through the eaves. The chirping was constant, as if it was the chicks calling their mother to feed them. I didn't call then but got in my new 1983 Chevy S-10 pickup and was driving up the Belleville turnpike. I was stopped at a red light and the birds were chirping to beat the band so I suddenly knew that it wasn't anything in the attic.
The birds go with me wherever I am, and they never cease. This is not a big deal as I tune them out unless it is very quiet, or I specifically think of them. The 'hum' is not like that. The hum is only in my condo, mostly the bedroom and adjacent rooms. It is not constant, comes and goes. Sometimes for weeks or months, years even. Point being, if it was tinnitus I think it would not be limited to that time/place.
Once, after a couple of years of dealing with this off and on, having no success at finding a local cause, I googled it and found it was a worldwide phenomenon I was relieved. I read an article on the hum where an expert in the physiology of the ear/hearing said that when we hear an unfamiliar sound we can isolate it unconsciously and turn the volume of it up within our ear, or turn it down.
The past few nights I have been fooling with that with some success. Kind like how I stopped worrying and learned to live with the hum. :)
