BB93 School Acoustics

There are five main issues with school acoustics covered in the Government's Building Bulletin 93 [BB93] "Acoustic Design of Schools":

• The reverberation time - a measure of how "live" or "dead" a classroom's acoustics are.
• The acoustic separation or sound insulation between classrooms.
• The acoustic separation of external (non-school) sounds from internal spaces, such as classrooms, halls and other teaching spaces.
• Sound generated by rainfall on the roof interfering with lessons.
• The acoustic isolation of internal noise (boilers, fans etc). 

See BB93 on Teachernet.  Note that Section E4 of the Building Regulations [E4] applies to schools, and compliance with BB93 is required.
