Comfort

Children have very powerful voices; they can exceed 90 dB, the sonic level of a buzz saw or a pneumatic hammer. This is a worrying: we urgently need to reduce noise in our creches and other school establishments (school canteens, classrooms, common rooms etc).

False ceiling slabs are very often used in company premises to rehabilitate worn surfaces and to hide technical equipment (tables, air conditioning, heating etc). False ceiling slabs also make it possible to reduce the ceiling height of a room.

Catering canteens (companies, schools and private institutions) are known for their relatively high level of noise.
