A passive sound-reduction kit for the Pilatus PC-12 lowers cabin noise by 55 percent in the speech interference level and by 80 percent in the average “A” weighted scale, according to Western Aircraft, the Boise, Idaho company offering the kit. The kit uses a variety of soundproofing materials installed throughout the cabin of the turboprop single, adding between about 90- and 120 lb to the aircraft’s empty weight. The kit costs $21,602.
