NOISE ATTENUATOR AROUND THE HEAD
Each “ANCAS” seat is equipped with an electronic noise attenuator which automatically calibrates for the noise emerging around the head of the user.
Each seat operates independently and provides maximum acoustic comfort for passengers.
ANCAS is based on electronic noise reduction techniques developed by TechnoFirst. This product was developed in cooperation with Dassault Electronique.

08Vehicle Exhaust Noise Control – Public Address
DYNAMIC EXHAUST SILENCER
The ExAct is a dynamic exhaust silencer for all types of internal combustion engines. It reduces low-frequency noise in real time regardless of engine acceleration. It simplifies and reduces the size of traditional exhaust lines and reduces consumption. It can also create a desired noise.
ELECTRONIC LONG WAVELENGTH NOISE & VIBRATION REDUCTION
The Novacs is able to process, with or without synchronous reference, periodic, broadband and pulsed signals.
