I stopped on my way through town this morning to re-seat an earplug, which was letting in some wind noise.
I always ride with earplugs.
It's no secret that riding a scooter or a motorcycle without earplugs causes hearing damage. Hearing damage causes hearing loss. It is cumulative.
Some are mislead to believe that certain helmet brands or styles will prevent this hearing damage. ALL helmets permit damage from the air movement about the head.
Every ENT doctor on the planet, and every reputable riding source promotes wearing earplugs.
Some riders say it is not safe to ride with earplugs. It would be much more accurate to state, "They do not feel safe wearing earplugs."
Do some reading - you might decide to wear them, always - as I do.
