Aircraft noise monitoring
Much of ERCD's noise monitoring work is undertaken on behalf of the DfT's 'Aircraft Noise Management Advisory Committee' (ANMAC). ANMAC advises the Government on policy relating to aircraft noise at Heathrow, Gatwick and Stansted. The work involves the collection and analysis of aircraft noise, flight path and other operational data.
Tasks carried out for ANMAC have included the provision of data in support of a review of the aircraft noise limits around airports, and the assessment of night-time community noise intrusion caused by ground activities at airports.
At Heathrow, Gatwick and Stansted, routine noise and flight path monitoring is carried out continuously by the airports' Noise and Track Keeping (NTK) systems. ERCD obtains data from the systems via its own workstations. In return, it provides specialist technical advice on NTK system enhancements.
For specialist projects, ERCD also uses its own noise monitoring equipment to measure and record aircraft noise levels.
