Hiya,
I would like to correct what DudeMannDude has said above, as it is not accurate and could cause unnecessary anxiety to people. Plenty of people do recover from tinnitus (I'm talking recovery, not habituation). They just don't tend to hang around on this forum...
I have recovered from tinnitus in the sense that it is barely audible (including in a quiet room) most of the time. This is including when I am actively looking out for the tinnitus. My recovery isn't just habituation - the actual volume of the tinnitus went down substantially to the point where most of the time, I don't have any sounds at all. I can put my fingers in my ears and the only sound I hear is the sound of my fingers rubbing against my ears.
However - if I feel stressed and start trying to listen out for the tinnitus, after a few times of "checking" it will come back (especially if I am anxious over a period of time). And it will come back in full swing (i.e. it's loud enough and annoying enough that I can hear it quite prominently in most situations). And it will hang around...
For me personally, if I do yoga, mindfulness meditation, swimming, remove stimulants and adopt a positive mindset, it really helps with the tinnitus volume, to the point where it backs right off. Conversely, if I actively listen out for it (and keep that up) it triggers it...
The mind is a powerful thing...everyone's brain has neural activity going on...it's probably best not to teach your ears to hear it by looking for the tinnitus! Pretty well everyone can hear their own tinnitus when placed in a totally quiet room (they've done studies on this - something like 95% of people hear tinnitus in this situation)- but if you're a sensitive person by nature and you teach your brain to hear the sound of its own neural activity...well...you can guess what happens next.
For those who are striving towards habituation - as tempting as it is, constantly monitoring tinnitus won't help with that...so try to get out of the habit of monitoring!
