Educated motorcyclists know that wind blast can damage hearing. We wear ear plugs inside our helmets.
Cyclists think they're not fast enough, but riding 10 mph into a 20 mph wind is enough to be significant, especially hours on end.

For you, I recommend foam ear plugs.

For others whose hearing isn't damaged yet, look into Cat Ears; they really work. Not as well as ear plugs, but they don't give any sensation of losing the desired type of hearing:

I finally bought a pair for my regular road helmet. I added a helmet with built-in LEDs recently, went for one ride on a windy night and came home with an earache. I'm ordering another set. Oh, and they're US-made.
