Yup, I started into all that sound deadening stuff too. Then realized
I could just buy the Bose ANR headsets and get all the "sound deadening" where
it matters - at my ears. The other bird I killed with that stone was to
discard the vise-like and musically challenged David Clarks. That EAR
stuff is heavy.

> Even though I am merely flying a lowly 320, I did employ the
E.A.R. suggested noise supression material along with ensuring that the
D-section (forward of the main spar in the stub wing) damped the "guitar
sound-box" effect. I have various foam/dead aluminum on the firewall, nose
wheel well, bottom and side fuselage walls as far back as the seat
back. Unfortunately (for me), after attenuating those noise sources, the
cabin cooling NACAs and the "hot-house" canopy (3/16", Later versions were
thicker) contribute more to the cockpit noise (prop generated) than those
supressed areas.

even thicker canopy "glass", wee props (if any) and a more indirect cockpit
cooling air source. Or, maybe we should just all wear HELMETS with ANR
(ignoring any passenger needs - see ***). You know,
