Dan,
Unfortunately I'm unable to help you with any noise testing as my ES
is not flying yet. I have the factory soundproofing kit and will admit it is
a bit heavy! I haven't installed too much of it only under the floor. I am
interested though in your progress and do appreciate any of your post. Good
luck with your project!

Subject: [LML] Lancair acoustic testing
Hi Folks
I've been working with Steve Myers on his acoustic insulation for his ES
and
have a very positive response from the samples I sent. I think the
insulation design I came up with will save a lot of weight ultimately and
be
very effective (it uses glass insulation batting and a light weight closed
cell foam barrier) but I would like to do some experiments using a
portable
noise meter. By the way, you may remember the posting I did awhile back
on
acoustics. I did kind of a general description of design parameters since
it
appears that the existing design is quite heavy.
Would anyone out there be interested in working with me on developing an
improved acoustic insulation system? You would end up with a quieter and
probably lighter plane for the price of some rides although I can throw in
some gas money. I would end up with a better design for insulation.
Since I'm building an ES, sure, I'd rather go with one of those but
actually,
probably any other model would give us the data we need.
I would need to test the baseline acoustics, see where the noise is coming
from and what the levels are at different speeds/attitudes. Then we would
have to test the plane with different types of insulation. There will be
a
few hours of work here but probably not too much time (sadly) on the
plane.
If you are intersted, I'd like to here from you. I live and work in the
San
Francisco Bay Area and I am close to the Oakland (OAK) and Hayward (HWD)
airports. I can get to the Concord (CCR) and Livermore (LVK) airports
relatively easily also.
I design these systems for large commercial aircraft, corporate jets and h
eads of state planes but haven't had the opportunity to work on the small
planes. The company I work for (the Orcon Corporation at www.orcon.com)
has
offered to let me do some development work and they will supply the
blankets
but this is really my project.
And if you've seen my other postings you probably know I also design and
build composite parts, too.
You may want to call me direct at (510) 476-2150 in the office.
