World Health Organisation publishes new guidelines on aircraft noise

The World Health Organisation Regional Office for Europe (WHO Europe) has published its long-awaited environmental noise guidelines.

For noise exposure averaged across the day, evening and night (Lden), the guidelines strongly recommend reducing noise levels to below 45 dB Lden (45 decibels with extra weight applied to evening and night), as aircraft noise above this level is associated with adverse health effects.
For night noise exposure, the guidelines strongly recommend reducing noise levels to below 40 dB Lnight, as aircraft noise above this level is associated with adverse effects on sleep.

In the National Policy Statement (NPS) for Heathrow the government failed to even mention WHO guidelines. Will they continue to ignore the guidelines and human health impacts of noise in their enthusiasm to promote more airport growth?
