@lhester10 I just read a great article today in the latest edition of Hearing Health magazine, which is the quarterly publication from the Hearing Health Foundation (hhf.org). They are currently doing research into hyperacusis and part of their funding is coming from a non-profit called Hyperacusis Research Ltd. (hyperacusisresearch.org). The article was written by a founder of Hyperacusis Research, Bryan Pollard, who decided to start the Foundation when he couldn't find adequate information online. Their website has a lot of good info also. HHF also is doing research into Tinnitus, so it is worth looking at both websites for info. Another source is the American Tinnitus Association (ata.org). Good luck.
