Ron,

Doesn't your intercom have squelch?  If it does then you shouldn't hear any 
noise from the mike.  I flew my plane with no interior for some time and 
expected it to be a lot quieter with upholstery.  I used cloth over 1/4" 
foam.  The effect on the noise level was disappointing.  I used a sound 
level meter to measure the difference with and without upholstery and there 
was only a 2db drop.  Hardly enough to even notice.

Your mileage may vary.
