I suffer from Tinnitus, and I mean REALLY bad, so hearing protectors are a very important part of my safety gear but it seems none I have tried actually come close to their claimed rating in noise reduction. Back at the mines I had a set of military issue protectors that worked really well but those are long gone and now even the Peltor brand I have been using are starting to deteriorate from age and usage. These things (the Peltors) have a NRR of 30 and I suppose they will meet that IF the ear cups are squeezed tight with my hands so it's as if the spring headgear is not strong enough, a stronger spring would get uncomfortable however. What I am looking for is something like the military issue outfit I had, the ear cup pads were filled with some type of gel so the spring headgear did not have to hold them tightly to seal out the noise. Those things WORKED but I can't find anything close to that now, the odd thing is they were rated at NRR 30 also but were much better than the Peltor brand or any others I have tried, Currently I use foam ear plugs along with the Peltor earmuff type and while it works fairly well it does not work well enough for my lawn mower, or worse yet, the string trimmer. I am open to any suggestion for solving this problem and I would like some opinions on protectors before ordering a new set.
