I'm in the early stages of the homebuilding disease :-P and still don't
know exactly what I want to build, just that I want to build something.
I'm interested to know what people have done in their aircraft to reduce
the interior noise level? Can such noise insulation be added to plan or
kit built aircraft without too much difficulty? Is it possible to reach
car or commercial airline jet noise levels in a homebuilt? Thanks,

David
