13. Quadrille Academy Acoustic Engineering “ A classroom with a long reverberation time of several seconds will cause syllables to be prolonged so that they overlap and hence degrade speech ineligibility. Adding acoustic absorption will reduce the reverberation time and will improve speech intelligibility.” DfES (2003) Building Bulletin 93, Acoustic Design of Schools
