Acoustic Design of Schools – A Design Guide. BB93 . Used by Acoustic Associates (Peterborough) in noise assessments for educational buildings.
BB93 specifies the acoustic performance standards for schools; these recognise research which has shown that acoustics play a vital role in the learning environment. BB93 defines seven Performance Standards which aim to achieve clear communication of speech and optimal acoustics for study activities, they are:
1 Indoor ambient noise levels in unoccupied spaces.
2 Airborne sound insulation between spaces.
3 Airborne sound insulation between circulation spaces and other spaces used by students.
4 Impact sound insulation of floors
5 Reverberation in teaching spaces.
6 Sound absorption in corridors, entrance halls and stairwells.
7 Speech intelligibility in open plan spaces .
