"Id like to hear from people what they are actually flying when using the different type of sets, i can beleive that ANR would have difficulty keeping up with very noisy environments like the pitts."
I do a lot of low-level stuff, and wear an old ex-USAF helmet re-wired with Dave Clark internals, and that is what I used in the Pitts. This is a very old helmet, and quite heavy, so I am considering upgrading to a CGF Gallet helmet. Has anybody got any feedback on the Gallet helmets?
I have found ANR headsets to be fairly useless in very noisy open cockpit environments, they are designed to cancel a fairly specific range of frequencies in a typical cockpit, and don't do much for wind noise or 'raw' engine noise. I have found that passive units fitted with the Oregon Aero 'Mic Muff' work better than ANR units in these applications. It is important that if two headsets are in use that
both have these fitted, or you lose the benefit. I'm not actually sure how they work, but they do work.
