I do theatrical backstage work. Like many of us, I have a degree of hearing loss, and I'm not happy about it. If I can't hear or understand instructions in my work, I'm doomed to have to redo things or ask again for instructions (or both). If I'm running a spotlight, I HAVE to be able to hear the directions through a headset from the lighting director. If I can't understand the instructions, I'll likely be replaced. That's lost income on top of being embarrassed.
I've come to consider earplugs to be just one more part of my riding gear. I don't ride 20 minutes without a helmet. I feel the same about the plugs.
