Sorry to hear about your ringing. I am close to 60, have some mild/moderate hearing loss (loud concerts, subways, IEM's) and some minimal tinnitus. I have done a fair amount of literature review on hearing loss, tinnitus and I will share a couple of findings for interested parties. First, excessive listening levels for portable devices are very common and it appears that hearing loss can occur at Spl levels below the OSHA standards(study below indicates 80 dB). Second, the idea of custom equalization based on either pure tone thresholds or equal loudness curves turns out to be dangerous from a medical standpoint (although appealing from physics perspective). A study showed worsening of tinnitus with overcompensation of hearing loss (by changing the equalization). There are many posts about how to equalize your headphones based on this method and it's possible if you are young, have normal ears it is fine, but for the older population-beware. The "notched music therapy" (the opposite--cut the tinnitus band out) may or may not be effective but no study has shown it hurts anything. The other problem with boosting the frequencies you do not hear well, is potential acceleration of the "noise" induced damage to those frequency bands (since they are impaired to begin with). Unfortunately there are NO generally accepted medical treatments for either tinnitus, nor noise induced hearing loss.
I have an android app that will help determine your listening Spl levels if interested.
