latest studies show that ANR is not so good as hearing protection and you are just as vurnable to hearing loss due to high frequency exposure using it.
We've always known that ANR primarily deals with low frequency noise, and it's the padding that primarily attenuates the high frequency noise. But "just as vulnerable to hearing loss" is news to me, and I'd be interested to read the studies if you have a link. Anyway, for me the hearing protection is a (very important) secondary benefit of ANR. The main reason I like it is because I can hear what's happening with the aircraft so must better.
Bellsux are you happy to share the price?
They quoted me near enough $A 2650 + gst
