Seville airport’s «Interactive Noise Map» unveiled

The airport of Seville has made an ‘Interactive Noise Map’ accessible to its users, neighbors, and local councils, which will provide public information on the trajectories followed by aircraft on their approach to the aerodrome, as well as on acoustic exposures.

The system is a visualization system, which will be accessible through an application called WebTrak, and for which it has been necessary to previously deploy a network of noise monitoring terminals (TMR) in several strategic points around the airport.

This tool allows users, within a simple and intuitive graphical environment, to perform different types of queries:

-View aircraft movements in flight, as well as data corresponding to code, altitude or aircraft type, for a historical interval of 60 days (with a 30-minute time lag for safety reasons).

-Represent the noise levels recorded in the TMRs installed around the airport and the data of the aircraft that caused them.

-Select the time period and/or the geographical area to visualize, allowing to identify the noise produced by the aircraft in a specific area or a specific period of time.

-Calculate the direct distance between any aircraft and the place (a house, for example) it is flying over.

In addition, WebTrak offers the option to file a complaint or claim regarding a specific aircraft, transferring directly to Seville Airport the information associated with it for its corresponding analysis.

Information transparency policy

The interactive noise maps make available to users, in a clear and transparent manner, the noise data and aircraft trajectories recorded by the monitoring systems installed at various airports in the Aena network.

These maps respond to the transparency policy implemented by Aena regarding the environmental management of its airports, with the aim of improving and expanding the information provided on the acoustic exposure of the airports’ surroundings.

Other airports

The implementation of this tool is being carried out gradually and linked to the installation of new noise monitoring systems. The first airports to use it were Adolfo Suárez Madrid-Barajas and Josep Tarradellas Barcelona-El Prat, followed by Valencia, Alicante-Elche Miguel Hernández, Málaga-Costa del Sol, Palma de Mallorca, Gran Canaria, Bilbao, Ibiza, Tenerife Norte-Ciudad de La Laguna and Tenerife Sur.
