The aim of Building Bulletin 93 (BB93) is to provide a comprehensive guide
for architects, building control bodies, building services engineers,
and others involved in the design of new school buildings.
BB93
gives the performance targets for compliance with Requirement E4 of The
Building Regulations Approved Document E that "each room or other
space in a school building shall have the acoustic conditions and the
sound insulation against disturbance by noise appropriate to its normal
use".
Acoustic
performance standards are specified for the following:
 indoor
ambient noise levels
airborne
sound insulation between spaces
impact
sound transmission of floors to spaces below
reverberation
times in teaching and study spaces
areas
of sound absorbing finishes in circulation spaces
speech
intelligibility in open-plan spaces
All
school buildings must conform to BB93 and are subject to detailed design
checks and on-site inspections. The document BB93 can be found at www.teachernet.gov.uk/acoustics
