Gulfstream 200 Cabin Reported Quieter, Lighter

Gulfstream is now delivering the G200 standard with a thermal/acoustic interior, which is said to reduce both aircraft weight and cabin noise levels. The weight saving is at least 150 lb, according to Gulfstream. Acoustical testing is planned for later this month and measured noise is expected to be about 55 dB on the speech-interference-level scale. The package is being provided by long-time Gulfstream supplier EAR Specialty Composites of Indianapolis. Thermal/acoustic packages include skin- and panel-damping treatments, overframe blankets, insulation, isolation systems, baffles and mufflers.
