Pol 05 - Reduction of noise pollution

Achieving a reduction in noise levels where background levels are low - KBCN1692

Where existing background levels are low, such as during night-time, there is no dispensation or flexibility that can be applied in achieving the requirements.  The aim of the issue is to reduce the potential impact of noise from the assessed building to local noise-sensitive buildings.  Acoustic experts have confirmed that the requirements for the background noise levels are still appropriate where existing levels are low, including where a 5dB reduction is stated within the criteria.
