If you are looking for a place to spend your money, you can spend
more and
get a better result by spending it on noise canceling headset(s). If
that isn't
enough, you can send the surplus to me!

When I did my rebuild, I applied sound deadening material like
this http://www.aircraftspruce.com/catalog/appages/dampingpanels.php
on the Firewall. The effect seems to be marginal. The noise seems
to come from the wind shield itself and nothing one can do to
mitigate the noise level here.
But for what it's worth, applying that stuff to the firewall does
not do harm either. It keeps the heat away in summer. It also does
not weigh much and can be removed fairly easy, so go and spend your
money. :-)

Since I'm getting rebuilt wing tanks, as most airplane projects go,
it leads to other things. Has anybody added sound deadening
material directly to the aluminum skins, behind the interior
upholstered side panels? Maybe the trade off between reduced
decibels and added weight is not enough to justify it.
I was just looking in an industrial supply catalog for other items
(as part of my job, NOT airplane parts) when I came across sound
deadening material, and wondered if there is an equivalent aircraft
grade?
