ANCAS®

(Active Noise Control Aircraft Seat)

Electronic noise attenuator for aircraft seat

Presentation

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.

principle

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.

Performance

Emerging noise attenuation: 20 to 30dB (50-500 Hz).
Broadband attenuation: 5 to 10dBA.

Technical specifications

  • Dimensions: adaptable to all types of seat.
  • Weight: 1.3kg.
  • Consumption: 15W.
  • Power supply: 28V DC or 115V/400Hz.
  • MTBF: 15,000 hours.
  • Approved by seat manufacturers.
