Cafeterias are large, cavernous spaces that are usually made from highly reflective cinderblock or gypsum board walls, have easy-to-clean tile or surfaced concrete floors, are surrounded by windows and more often than not, hard board or steel ceilings. In order to maximize their use, they are often considered multi-function rooms that are used for lunch breaks, meeting spaces, auditoriums and social settings. The hard surfaces reflect the sound from voices, the clanging of trays and cutlery and general kitchen noise back into the room creating a din. In effort to communicate, the folks inside elevate their voices and the noise levels increase to the point where the room becomes uncomfortable.
During school lunch breaks, these quiet caverns turn into a cacophony of yelling and screaming as the cafeteria fills with kids exposing teachers and guardians with excessive noise levels that can cause permanent ear damage. For meetings, a PA system is deployed and no matter how articulate the speaker, it is practically impossible to hear what is being projected due to the competing echo and subsequent reverberant field caused by the hard reflective surfaces.
Fixing Pyrosorb to the ceiling using mechanical fixings will help to absorb some of the noise, we also recommend treating the walls with acoustic panels such as Bubblesorba. For a primary school, perhaps a more fun look is desired, Flat System comes in many shapes and bright colours to brighten up any cafeteria. For a first floor Cafeteria, a product such as Floorsorba will absorb footfall noise.
