Thermal/Acoustic Package Cuts Cabin Noise by a Third

Business aircraft management and charter operator Zenith Jet and noise reduction specialist Aviation International Management Services (AIMS) have teamed to launch a new thermal acoustic barrier package that promises to reduce cabin noise by up to 30 percent. AIMS is supplying the kits and Zenith Jet is the exclusive marketing agent. Silentium Air SPS 360 was developed by Montreal-based AIMS and has been installed and tested in more than 30 business aircraft, from a Learjet 55 to a Boeing Business Jet. The result, according to AIMS v-p of program management Abdul Hajibrahim, is a reduction in average cabin noise of as much as 5 dB (SIL), the equivalent of a 30-percent drop. Weight advantages accompany the noise reduction: according to AIMS, the total package for a Challenger 601 used as a test aircraft weighed 500 pounds less than the factory-installed standard thermal/acoustic system. The AIMS package for a Challenger is priced in the $200,000 range. The first kit to receive an FAA supplemental type certificate is being installed in Canada on a CRJ200 executive conversion by MJet of Dorval, Quebec.
