Hi @mzhp1988, a member of our HLAA chapter has hyperacusis and tinnitus also. I found an article for him in the Hearing Journal which also references a couple of other articles at the bottom. This Mayo Clinic blog won't let me post a link for some reason. So Google The Hearing Journal and search their site for articles on hyperacusis. I also found reference to hyperacusis in the Hearing Health Foundation's website hhf.org. Go to the site and Search for hyperacusis and tinnitus. They are a non-profit that is doing some great research in various areas, including Meniere's Disease and trying to regenerate hair cells in humans. Good luck with it.
