Road Traffic Noise Ireland

The use of Lden to assess traffic noise impact is simply incorrect. The Lden  metric was developed for noise mapping purposes ONLY and NOT as a metric to assess ‘the degree of noise change’ created by a proposed road scheme. It would appear that much of the Irish guidance produced by the NRA/TII continues to suggest its use (using a design goal of Lden=60dB), however the Lden metric is simply too coarse of a metric and is not fit for this purpose.
