I’ve had ringing in the ears ever since I was a kid. Most of the time, I can ignore it. But if it is real silent, it’s tough to do.
I have it bad enough so I can’t really take a hearing test because of the constant tones I hear. Sounds just like the tones generated by the test machine. I was once accused of being coached on a hearing test because of the number of times I was pushing the button, when there was no tone generated. The situation is definitely worse when it is quiet.
