In 2001 new proposals were issued for public consultation regarding changes to the English and Welsh Building Regulations Part E "resistance to the passage of
sound" and guidance document Approved Document E. Several major changes were proposed in these documents ...
One of the most important changes was the proposal to introduce IS0717 spectrum adaptation terms, Ctr for airborne sound insulation of separating walls and floors and Cl for impact sound transmission for separating floors. The new proposals outlined that changing to the new measurement criteria and sound insulation levels, the current sound insulation performance would be improved by +3dB for walls and +4dB for floors.

To evaluate the impact of introducing such proposals to the Scottish Building Regulations Part H "resistance to the transmission of sound" a study was undertaken to investigate their implications in relation to the current standards and
methods of rating sound insulation used in Scotland.
