scott wants to know if soundproofing is worth the bother. In my opinion,it
is not. I put soundproofing entirely anound the cabin area of my 320 from
the firewall to the baggage bulkhead. The noise level is still incredibly
loud, due to all the openings around the canopy,thru openings in the
closeout ribs,etc. The process had to add at least 25 pounds and if I
didn"t dave excellent ANC headsets (Lightspeed) I would be totally deaf now
instead of only half deaf.I beleive that good upholstery and a lot of
carpet does as good a job as possible. Fred N9BF... Don't fly like my
brother!!!!
