Erratum – Criterion 9 – Indoor ambient noise - KBCN1569

The wording of criterion 9 is incorrect and should read as follows: 9. The developer commits to achieve indoor ambient noise levels in buildings and, where appropriate, external noise levels 5dB (or a meaningful and reasonable dB) below the “reasonable” targets set out in BS8233 or other appropriate good practice standards or regulations. This will be corrected in the next reissue of the technical manual.
