@Bill Bauer
With respect to you Bill I realize that you mean well but you haven't had tinnitus and hypercusis that long, although it's obvious your sensitivity to sound is quite acute. The solution to this is to seek medical treatment with a Hearing Therapist or Audiologist that is trained in the management and treatment of tinnitus and hyperacusis, and not to be scared of sound.
Over protecting the ears using earplugs and earmuffs at every opportunity, will inevitably lower the loudness threshold of your auditory system and make it more sensitive to sound and reinforce negative thinking. If you are not careful you might start to develop if not already phonophobia: a fear of sound. Keeping away from normal everyday sounds isn't the answer.
@fishbone has 30 years experience with tinnitus and is correct in everything he has said. I am a little behind at 21 years and my hyperacusis has been completely cured now for 18 years. I rarely use earplugs although I do carry them on my person. Touch wood I haven't had occasion to use them out on the street no matter how loud environmental sounds have been.
I disagree with you about some of sounds that you believe are dangerous to the auditory system that you have mentioned on this thread. They may be loud but certainly not dangerous. It is the fear, anxiety and negative thinking that will become dangerous to you or anyone else that follows your train of thoughts on this particular issue, of over protecting and hiding away from normal everyday sounds. Please seek help and save yourself a lot of heartache misery. The road you are traveling on I don't think it's going to be healthy for you in the long run.
I wish you well.
