Ya gotta love OSHSA....
For what it's worth, at 56 years of age I have been riding without ear plugs for 44 years and this will be my 45th season. During this time I have worked on military jets, piloted a 17 foot Cole winged T4 flat bottom drag boat (for 4 years), worked in an automotive service and manufacturing environment and some other really noisy places. At times I wore everything from mouse ears to ear plugs. My hearing is not perfect but I have no need for hearing aids or any other device necessary to help me hear nor do I find it necessary to crank it up when it comes to the TV, radio or music . Today, I can hear the brush on a symbol, the squirrel foraging in the woods, bird song and my grandkids asking to go riding or for a cookie. I will however say the one thing many riders face in terms of hearing problems plugs or not is what is known as "tinnitus" or ringing of the ears. In some cases this condition is permanent and in others it will go away. Either way I still hear very well and if I don't fix this bathroom faucet the drip drip drip is going to drive me nuts. I will also say I have my ears checked (audiogram) every two years just to stay on top of things.
