World leader in noise and vibration reduction technologies through active control (active noise control and active vibration control), the TechnoFirst Company has endeavoured, since 1990, to improve its customers’ acoustic comfort.
Building on their 25 years' experience at global level, TechnoFirst combines the power of an industrial group publicly traded on the Euronext Marché Libre since 2003 and listed on the Alternext market since October 2015, with the responsiveness of an engineering and design department organised into several complementary entities.
TechnoFirst have joined the SAFE Competitiveness Cluster. They are also involved in the Maritime Cluster, FCPI certified, (Fonds Commun de Placement dans l'innovation or Innovation-focused mutual funds), and are eligible for the R&D Tax Credit (Crédit d'Impôt Recherche or CIR). They also possess a Confidential Clearance accreditation.
PIONEERS INACTIVE NOISE CONTROL
It all began in 1987 with a doctoral thesis prepared and defended at the Laboratoire de mécanique et d'acoustique (Aix-Marseille Université/Centrale Marseille/CNRS), the oldest CNRS laboratory in Provence, by Christian Carme under the direction of Bernard Nayroles, on active sound absorption in cavities.
On the strength of this experience and results, Christian Carme created TechnoFirst in 1990, a company that has since become the world leader in active noise and vibration reduction technologies.
The principle of active control consists of generating a "counter-noise" that cancels out the primary noise.
That's how the first noise reduction system was born: the active noise-cancelling headphones.
There are two types of earmuffs: passive (without electronics) and active (with electronics).
In a very noisy environment, passive headphones can attenuate high frequencies (high frequencies) by 50 to 60 decibels, but low frequencies (low frequencies) by only 15 decibels. In active mode, the attenuation of low frequencies can be tripled.
Today, this technology is found all over the world, from construction site headphones to home music headphones.
