No, i don't think so. The noise is basically the turbulence of the airflow over/around the helmet. If you have a fairing, you'll note that the wind noise is much less.
Noise varies drastically between helment brands. My Arai is much worse than my Shoei. The Arai has a plastic cover over the shield hinge, and that thing is a noise amplifier. the Shoei, on the other hand, has a smooth shield without a cover. it is noticably quieter.
I always wear ear plugs, except after i rebuild an engine for the first ride or two to make sure i don't hear anything bad.
I am probably a geek, but i would always wear earplugs even going to bars with bands. My wife used to make fun of me, but at 44, she has measurable hearing loss. I may look stupid, but i'd rather hear.
Try earplugs on a long ride. you'll arrive MUCH more relaxed and fresh than if you didn't wear them. that ambient noise is very tiring.
