Under pressure from a pair of local high-profile congressmen, Howard Berman (D) and Brad Sherman (D), the FAA has announced it will hold a community hearing on helicopter noise in the L.A. basin during the first week of August. The hearing will take testimony from concerned parties that will be the basis of a report that could provide the basis for imposed and/or voluntary solutions.
E-A-R Thermal Acoustics Systems (Stand 2145) is improving acoustic insulation aboard business jets as it endeavors to cut the most annoying cabin noises on a case-by-case basis.
ITT has been quietly developing technology to reduce aircraft cabin noise levels, primarily through the use of cabin interior isolators.
The White Plains, N.Y.-based company promoted its latest products at the recent Business Jet Interiors World Expo in Cannes, France, claiming that in some cases the ITT elastomeric devices that attach the cabin interior to the airframe have reduced noise by up to 6 dBA. These same isolators are standard in the Boeing 787.
Thermal/acoustic specialist 3M introduced a new acoustic demonstrator from its subsidiary E-A-R Thermal Acoustic Systems (Booth No. N5930) here at the NBAA convention. The demonstrator was created to simulate not only interior noise levels of a typical business aircraft, but also the range of noise signatures with varying frequency content.
InspecTech Aero Service has launched its iShade iQ electrically dimmable window, and the new technology includes a breakthrough in noise damping, according to the Fort Lauderdale, Fla.-based company. “Cabin windows are a main path for noise transmission,” explained the company at the Aircraft Interiors Expo in April in Hamburg, Germany.
Lightspeed Aviation unveiled its next-generation Zulu headset last month at the Sun ’n’ Fun Fly-In. The new Zulu introduces several features, including “Microport Vent” technology that provides greater active-noise-canceling consistency, better fit and an improved microphone that adds more voice clarity and improved noise-canceling capability.
A new thermal/acoustic barrier package promises to reduce cabin noise by as much as 30 percent. The Silentium Air SPS 360 is a product of Aviation International Management Services (AIMS) of Montreal, which is supplying the kits to exclusive marketing agent Zenith Jet, also of Montreal.
Business aircraft management and charter operator Zenith Jet and noise reduction specialist Aviation Management International Services (AIMS) have teamed to launch a new thermal acoustic barrier package–dubbed Silentium Air– that promises to reduce cabin noise by up to 30 percent. AIMS is supplying the kits and Zenith Jet is the exclusive marketing agent.

Eurocopter is flight-testing low-noise approach, takeoff and cruise flight procedures with an EC 135 light twin. The trials are also serving to develop a software program for noise footprint prediction. Similar tests were conducted with an EC 130 last year.
