My name is Larry L. And I have tinnitus, a high pitched ringing. I first really realized there was an issue shortly after retiring 15 years ago. I worked in an extremely high noise environment 93.5 to 105 decibel for about 10 years. Because I wore earplugs most of the time at work my employer and the compensation board will not accept the fact that some of the responsibility should be on their shoulders. Are there any surveys showing information that could help ie... Is high pitched tinnitus related to what I did, is low pitched tinnitus related to a different activity? Are there many NIHL claims accepted or turned down? Any information would help. Thanks
