Section 8: Acoustic conditions in schools

8.1 In the Secretary of State's view the normal way of satisfying Requirement E4 will be to meet the values for sound insulation, reverberation time and internal ambient noise which are given in Section 1 of Building Bulletin 93. Acoustic design of Schools. A design guide, DfES 2003. ISBN: 0 11271 105 7.
