I assumed the vote was for motorcycle related activities. I simply won't own or ride or ride with motorcycles that are loud enough to require ear plugs. There is no justifiable reason to have a motorcycle loud enough to require ear plugs on public thoroughfares, imo.
I've been using Shoei Helmets since the 80's, I think. Thinking about going to an Arai for the next one.
At the gun range, airport, or other venues with loud noises, yes, I wear ear protection. I have molded ear plugs, and over the ear muffs, which I sometimes use simultaneously. I also have Peltor electronic ear muffs which block noise above db levels which are damaging. These are great at the gun range for teaching, as you don't have to yell instructions.
