>>106649236I had that for about 3 months two years ago (thankfully in my case it was a completely temporary issue that I was able to fix) and it was really goddamn annoying.
If the feeling is the same as mine, it's not really a noise. It's hard to describe but it's like a pressure that you feel and it has a 'noise' to it but it's not like a normal sound.
After a week or so you do somewhat get used to it but it's not a constant sound that you can get used to, it changes enough that you always feel it.
I had it in one ear only and if it were permanent, I think I would have rather lost hearing in one ear.
