Wa ! Fa ! La !
- The weight of the solution;
- Its size;
- The power consumption of the electronic processing of low-frequency noise;
- And the cost of these solutions.
FA is a new concept of sliding window allowing you to open your window without experiencing noise pollution from the outside.
For this, TechnoFirst exploits the complementarity of two treatments: electronic and passive. This combination provides noise attenuation of up to 25dB.
Did you know ?
Passive treatment consists of placing absorbent materials near the opening. Mid- and high-frequency noises are absorbed as they pass. The electronic processing makes it possible to attenuate the low frequencies. The integration of sensors and ultra-compact loudspeakers (designed by Fraunhofer IBP) driven by a controller allows the generation of counter-noise.
FA thus makes possible the natural ventilation of a room while maintaining high sound insulation.
Performance: up to 25 dB
Electronic processing band [20 – 500] Hz
