In order to determine the frequencies and amplitude of noise inside a
Lancair, I need a tape recording taken at the head position of each seat
while in cruise configuration.  A Sony tape and a hand held dB meter...both
of which can be purchased at Radio Shack for about $50 will suffice.  Mail
the tape to me with your voice recording describing the RPM and Manifold
readings and tell me which seat your are recording in.  A test of about 30
seconds per seat is fine.

I will then be able to tell you what effect my cabin noise control system
will have in your airplanes.

Please send the recording to:  Shelby Carr, 3901 Stanford, Dallas, Texas
75225.  My phone number is (214) 739-2688.  My web site address is
WWW.Quietflight-LLC.Com.  Be sure to use the hyphen before LLC.
Thank you, Shelby Carr, President
