Same thing for me. I started to hear it at night when the room was quiet 7 years ago, and then progressively all the time. The first year was hard, I saw a few specialists who told me there was nothing to do about it. In the end I accepted it and now it doesn't bother me anymore. The more you are upset about it and the worse it is. I only wish I could be able to hear the silence again, but there are worst things in life. My hypothesis is that it was always there but somehow the filter I had for it stopped working. A bit like eye floaters.
