Noise monitoring systems

Aena has Noise Monitoring Systems to measure the noise produced by aircrafts. Currently Aena has this system at the airports of Adolfo Suárez Madrid-Barajas, Alicante-Elche, Bilbao, Gran Canaria, Ibiza, Josep Tarradellas Barcelona-El Prat, Málaga-Costa del Sol, Palma de Mallorca, Sevilla, Tenerife Norte, Tenerife Sur  and Valencia.

Aena provides monitoring information from some of its airports by means of a control system which detects, measures and compiles the noise produced by aircraft that fly over microphones installed in strategic locations in the surrounding areas.

The system receives information of flight plans and radar paths, correlating them with the measurements taken by the Noise Monitoring Terminals (TMR), allowing the system to evaluate the data from around the general airport system. In this way, the characteristics of each sound event and all the data related to the aircraft responsible for said event are recorded: aeroplane identifier, position, altitude, airline, destination, etc.

The locations of the TMR are selected in order to measure the environmental noise levels in the points that are most exposed to aeronautical noise, close to air routes, and to improve the measuring and control of the level of noise pollution caused by aeronautical operations in towns that could be affected.

Noise monitoring is not limited to aircraft in flight, the noise of aircraft on land, particularly during the night, is also monitored in areas of the aircraft aprons close to towns bordering the airport.
