I worked my way up through the construction industry and now spend my days trying to convince people who are new to the industry to take care of their bodies. I do a hearing loss prevention presentation from time to time, and I'm a perfect example of why plugs are needed WAY more than we ever think to use them.
My children all talk loud. It's not that they want attention, it's that they think it's normal because that's the way I talk. Most hearing loss is cumulative, and in most cases, once it's lost you're not getting it back. Anything over 80db requires hearing protection in the workplace. And yes, my bike and probably most of yours operate at over 80db.
I'm new to riding and have just recently got my bike to a level that I trust on long rides. after an hour or two riding with my buddies, the noise is mind-numbing. Gotta have the plugs.
Joyflyin- I tried wrapping tape around my ears, but it made it really hard to see. Not to mention all the hair that came off my head upon removal.
