There is increasing pressure from the government to increase sustainability, therefore architects have been finding ways to help decrease the carbon footprint of their buildings.
This can be accomplished in schools by the removal of suspended ceilings. However it creates a problem for acoustic absorption, a job traditionally done by ceiling tiles, with these removed, sound is free to reverberate for longer.


The Silentium is a specially designed acoustic luminaire for classrooms.

The Silentium meets the requirements of DCSF building bulletin 93

SRL Test Report no. C/21329/R02

The reverberation time of <0.8 seconds was met without the need for additional acoustic baffles in the classroom. this is based on the parameters set out below.
