   Lots of comments on this subject. I may as well throw in my 2 cents
worth.
   I've been flying a Starduster Too -- very windy and very noisy. I
had a difficult time understanding what I heard over the radio, so there
was no way I would fly into or through the local Class B area. In an
attempt to improve reception, I bought a David Clark ANR headset. It
worked the same as my non-ANR unit. After a number of frustrating
flights I spoke to the DC people, who told me it should work better than
it had been and told me to send it in for repair. They actually replaced
it, but the new one works no better. Even in a closed airplane - a 152
or 172 - it doesn't make much difference if turned on or off. The noise
is different, but just as loud. In defense of DC I must say that when it
is tried in my kitchen it completely cancels the sound of the
refrigerator.
   Some time ago I had the good fortune to ride in Rick Argente's 360
and was absolutely amazed by the silence heard through his LightSpeed
units. I couldn't believe an ANR could R so much N. You can bet that
when my Lancair is ready to fly it will do so with LightSpeeds
installed.
