Have to agree with the above comments, "sounds" like you might consider earplugs, there's been discussion here on a wide range of styles. A search should turn up those threads. Myself, I go for the cheapo throw away foam rubber kind. I should have worn them to the Wishbone Ash concert in 1975, my ears are still ringing. Of course with Epco exhaust I rarely notice wind noise
. But it is interesting how some full helmets almost act like a sound chamber.
