PS Engineering has added “IntelliAudio” dimensional sound to its new PMA450 audio panel. Based on research conducted by the U.S. Air Force’s Wright Patterson Air Force Laboratory and licensed by PS Engineering, IntelliAudio allows the pilot to select where various audio inputs will sound as though they are coming from in the headset. For example, com 1 and 2 can be set in any of nine separate positions, so each audio source sounds separate and unique.

Professional audio company AKG broke into the aviation market on Tuesday with the introduction of an active noise-reduction aircraft headset, the AV100, at the Sun ’n’ Fun Fly-In. Its $1,099 headset uses hybrid active noise-cancelling technology and signal processing to attenuate the specific frequencies inside an airplane. Features include built-in LED map lights, as well Bluetooth connectivity and an auxiliary input for interfacing with navigation devices, tablet PCs, phones or other devices, allowing such things as Hi-Fi music streaming.

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.”
