I have the unusual need to decrease the sensitivity of my headset mike.
The
aircraft I fly has a very noisy cockpit (tube and fabric two stroke
pusher )
when I transmit the mike picks up alot of background noise. The headset
is
an avcom ac900 flex boom ,mike is an M71 I tried a mike from a DC headset
it
was better but still not great. Is there anything I can do to reduce the
sensitivity of the mike?

Thanks in advance , Peter T

Put a muff over it? A muff keeps mine from triggering the voice-activation
of the ancient Softcomm intercom in a Taylorcraft, which is noise incarnate.

I recently flew a 172 which was amazingly quiet. We could talk in the
cockpit without much noise at all while the 172 cruised along at 125. Now
I can see why it was so quiet because as we took out the interior, including
the door and side panels for replacement because they looked like hell, they
were plush and foam-backed. So were the carpets. The doors were stuffed
with fiberglas insulation and so were other little nooks and crannies.
