Business aircraft cabins are generally not quiet. Not with the turbulent boundary-layer rush of air around the fuselage at Mach 0.85 and the whine of a couple of jet engines no great distance from the comfy chairs. Then there are the pumps, hydraulics, fans, gears, actuators, electric motors, worn bearings and air distribution through the metal ductwork, not to mention the occasional hum of the microwave and induction oven, the rattling of glasses and flatware in the galley and that giant sucking sound coming from the lavatory.
Headset maker Lightspeed Aviation (Booth No. C11137) is offering a new aviation headset with a suite of options that offer a “personal flying experience” the company abbreviates as “PFX.” The options include “acoustic response mapping” and “streaming quiet.”
“Acoustic response mapping” uses sound waves and advanced signal processing to measure the user’s ear size and shape, adapting audio to each pilot’s “unique auditory landscape.”
Today at EBACE, Nextant Aerospace launched the $4.95 million 400XTi (the “i” stands for innovation) as the latest evolution of its remanufactured Beechjet.

A new noise-cancelling headset introduced in April at the Aircraft Interiors Expo in Hamburg, Germany, is set to find a market in business and private aviation.

Lightspeed Aviation unveiled its next-generation Zulu headset last month at the Sun ’n’ Fun Fly-In.
