It claimed the airport’s summer schedule exceeds the permitted number of night flights between 11 p.m. The notice was issued in late July after complaints about excessive noise from residents and gave Daa six weeks to comply. Judge Conor Dignam also granted Daa permission to challenge Fingal County Council’s enforcement notice, which accuses the airport operator of breaching planning permission terms related to the new North Runway, which opened in August 2022. The weightings are then added to the evening LAeq and night LAeq with each LAeq then added together, taking into account the period durations.Dublin Airport (DUB) operator Daa has secured a temporary High Court stay on a decision that could significantly impact nighttime flights to and from the airport. To compute the noise contours each period is considered separately and a LAeq is determined for it. In movement terms the effect of the weightings is equivalent to more than trebling the number of aircraft movements during the evening and multiplying by 10 the number of movements at night. The unit is therefore biased to respond more to noise in the evening, and particularly at night, than during the 12 hour day. If it occurs during the evening (19:00-23:00) a weighting of +5 dB(A) is added and if it is at night (23:00 – 07:00) a weighting of +10 dB(A) is added. If the noise is during the 12 hour day (07:00 – 19:00) there is no adjustment. LAeq.T is an energy average and is defined as the level of a notional sound which, over a defined period of time, would deliver the same A-weighted sound energy as the actual fluctuating sound. LAeq.T is the most widely applicable unit and is the equivalent continuous A-weighted sound pressure Level. The Lden unit is a LAeq for the whole 24 hour period but includes weightings depending on when during the 24 hour period the noise occurs. The European Directive 2002/49/EC on noise mapping requires noise contours to be generated using the Lden and Lnight noise indices. ![]()
