Every ANCAS seat is equipped with an electronic noise attenuator automatically calibrated for emerging noise. Every seat operates autonomously and provides passengers with maximum acoustic comfort.
ANCAS is based on the electronic noise reduction techniques developed by TechnoFirst. This product was developed as part of a cooperation with Dassault Electronique.
Every ANCAS seat contains an electro-acoustic module which detects ambient noise and produces its counter-noise to eradicate it. This creates an acoustic comfort zone around the headrest, optimising the well-being of passengers. These resulting adjacent quiet zones reduce the overall noise level inside the passenger cabin.
Emerging noise attenuation: 20 to 30dB (50-500 Hz).
Broadband attenuation: 5 to 10dBA.
