En-Route
I've got a Russian flying helmet I converted for use in my Fly Baby several years ago. I never used it much, since I now have an ANR headset that treats my ears much nicer.
(Conversion story at http://www.bowersflybaby.com/stories/helmet.HTM)
Anyway, I had to send my ANR unit in for repairs a while back, so used the Russian headset last weekend. Turns out the speakers had badly deteriorated and, once aloft, I couldn't make out more than one word in ten.
I got the idea to replace the speakers with IPod earbuds to try take advantage of the additional attenuation of an in-the-ear speaker. The problem is, it leaves a big gap in the helmet where the speakers used to be. These are under a hard-rubber outer shell, so it's not like it exposes my head.
But I've got a gap, and am wondering what the best noise-attenuation filler should be. Should it be light and fluffy, like expanding foam, or solid and dense like metal or wood?
Any thoughts?
