Sure.
We are using an GUH-68P without ANR. In our 8A if you push the throttle up full the sound will overload the mice and the audio. What we did was get the Hush kits from Gibson & Barns and install them with a new noise canceling mice. This makes for a better sound reduction inside the helmet shell. I now fine that it is when I make a high speed run that the wind noise is great enough to trip the mice and feed back into the audio. It only lasts as long as I hold the throttle up full and the air speed up high. When we drop the throttle bellow 80% and the speed bleeds back off a little the audio goes back below the squelch limit. I talked to the guy from up at Flight Helmets.com this year up at OSKH and he is retrofitting helmets with the Boase X system. I do not know how well this works and his price is almost the cost of a new GHU-55 by itself. For us we do not have any sound proofing in the 8, so over time I know that this will get better as we install panels and felt seals. I fly it both ways, with the helmet and with standard head sets of a few brand names. I think the helmet is a better sound deadener, but it does get hot in the summer time when you are down low or on the ramp. The good mil. spect. Skull Caps help, but you need two or three so you can wash one as you rotate to another fresh one. Hope this helps. Yours, R.E.A. III #80888
