For the first time in over 20 years the Building Standards Division (BSD) of Scottish Government has undertaken a major review of Section 5: noise of the Technical Handbooks.

This paper provides an overview of the research undertaken to establish the increase in sound insulation performance levels and the relevance of sound insulation testing.
