Hey.. I have the same thing. Right now as I type this I'm listening to music and have a silicone ear plug in my right ear. Without it, I hear a whistle, ringing, distortion, sizzle type sound at certain frequencies and it's as loud as the music.
It's sort of like I'm getting microphone feedback inside my ear. If I plug it up then it goes away but I have to live now with an ear plug in my ear most of the time.
I've had it looked at by a few specialists and they can't do anything for me. No cure. They say it may settle down after awhile. Some days are better than others but it's frustrating and depressing.
I don't have any solutions but I wanted to respond to let you know you're not alone
