Now where's the fun in that! 
I think a lot of my noise is due to my Scorpion modular helmet and I am waiting for delivery of a new full face Icon helmet. I have to agree that my old Jet lid was much quieter but I was getting too many bugs in my teeth! 
I would ideally like to 'inject' some anti-noise into my Sena bluetooth helmet system - that way I can lower the sound of wind, traffic, pipes etc but still have my phone, music, intercom, satnav etc. I am surprised that (to my knowledge) a helmet manufacturer hasn't marketed such a system yet.
