For more than 70 years, FACTEM has specialized in the design, development and manufacture of acoustic cells (microphones and earphones). This knowledge, sought after by the major players in the aeronautics industry, has allowed us to take our place in a fiercely competitive market. We design and manufacture quality products which are well-known in France and overseas, in both civilian and military sectors. We are continuing the development and production of acoustic products taken over from SILEC and SAGEM.

We manufacture a wide range of aeronautical products (headphones, and hard hats with built-in communications, radio/loud speaker combination, genephone etc.) as well as the associated accessories and connectors. Protection against noise pollution has become a priority in all sectors (military, industrial and for the general public etc.). With ever-increasing human and material resources, FACTEM has, in recent years, lead research in the field of active protection (ANR) and that of passive (choice of materials, earpieces etc.).

Beyond supplying equipment, we are now able to offer complete solutions in the form of audio and acoustic systems allowing wired or wireless communication in a controlled industrial or military environment. As a member of national and international acoustic associations, FACTEM takes part in several European projects.
