I’ve got a couple of hearing protection questions: What is the minimum recommended NRR? Right now the highest rating I’ve seen is 30dB, in the “AO Safety/ Peltor Bullseye 10” (I’m sure there are others with this rating as well). Am I going to get much higher than that? Does it even matter – where does the law of diminishing return come into play? For all I know 25 might preserve hearing just as well as 30. I’m not really interested in the electronic models. It would be nice but they seem to always be rated lower than similar non-electronic models. If there is a model that will give maximum hearing protection I would consider them though. I’m not going to sacrifice my hearing just to hear the repeated “Down 1”, “Down 3”, and “Down 5” from the IDPA scorekeepers. I ask these questions because I recently noticed the muff’s I’ve been using have a rating of 21 and it seems I could do better. Thanks folks.
