I've been to concerts where I've had it for several days afterwards. It's always been a big fear of mine since I can't imagine anything more annoying. I honestly don't know how people stay sane never being able to enjoy quietness.
That used to happen to me. Take my word for it, if you keep doing that (without taking precautions, such as I suggest below) eventually the whistling noises won't go away, you'll have them 24/7 for the rest of your life!
OK, how many here have this condition ? I've had it for years .. some hearing loss as a result. Back in the day to much loud music and while in the Army I didn't use my ear plugs while in my track vehicles ( M113 ) and around M60 tanks at the motor pool.
As long as I'm around some noise I don't hear it. But at night ( year round ) I have to have a fan on to cancel out the ringing. If you have this condition how do you cope ?
I have had it for many years, too much loud music is, I figure, the cause. It's the result of nerve damage to your ears and my doctor tells me there's no way to reverse that damage. I've had it so long that most of the time I don't notice it or think about it, but if I do think about it, yeah, I hear it. I just ignore it. Yep, it fucks up your ability to hear things. I don't do well in noisy environments understanding conversations a lot of the time, unless people talk loud enough. Some people I understand better than others, depends on their enunciation, the peculiarities of their voices and speech patterns.
I had my ears tested about 10 years ago and they said below 3000 hz my hearing is normal but is attenuated by about 50% from there up.
There are many kinds of tinnitus, it is experienced quite differently by different people. You will learn that if you do a google search.
I don't bother with white noise to combat tinnitus. I'm considering it to combat noise from my neighbors. One neighbor has the TV on 24/7 sometimes for days and weeks, another has some kind of machine that makes a constant tone around 200hz. I've talked to both these, the first just doesn't get it that other people might not want to hear their TV, the other said "what sound?"

I think they are just plain liars. No, it's not my tinnitus, they have some kind of machine on there... To deal with my neighbors I've been shoving silicon ear plugs in my ears every night before going to sleep. Shove it in tight! I called the cops on the TV lady one night around 1:30AM. Not sure they came. Have talked to her once, left a note or two. They are incorrigible. I could call the cops again, maybe get the city after them and the tone people too, don't know if they would/could be any help.
You people who go to loud concerts -- yeah, loud music is fun, but a lifetime of tinnitus could be the price you pay if you don't wear some ear protection, whether it's ear plugs, wads of cotton or even cigarette filters or pieces of paper you wet with spit and shove in your ears. You don't have to kill the sound completely, just attenuate it enough where you don't damage the nerves in your ears.

I sometimes wear sound muffling ear muffs (sold for that purpose at Harbor Freight), around the house when doing loud blender jobs or use loud electric tools. I want to protect what hearing I have left. Both my parents went practically deaf eventually... I think my hearing's been pretty stable for many years, but I am considering having another hearing test. My hearing may have changed and the test I had may not have been conducted correctly.
