Came across this story today. I am not sure if this has been posted before, but user "quietkids" on this page reports having recovered from Tinnitus after an acoustic trauma when posting about it 4 years later. I think it might be helpful to some. http://forums.webmd.com/3/cold-and-flu-exchange/forum/4948 Especially the last few posts could be interesting. The user reports "no more lingering tinnitus".
