Why Should You Wear Ear Plugs?
For some reason, it's not "cool" to be seen wearing earplugs while riding a motorcycle. I know I probably sound like dear old Mom, but let me tell you something -- it's not cool at all to lose your hearing, and it's really, really easy to do so.
Motorcycling is a very noisy occupation. Sound levels can easily reach over 90dB at only 50mph, and 90dB exceeds the levels at which hearing protection should be used.
If you were working inside a factory, various local and national governments strongly advise wearing hearing protection at those levels.
At 60mph, a motorcyclist can experience the same noise as if using a circular saw (100dB).
