Minimising the noise impact generated by air traffic is one the main concerns for Adolfo Suárez Madrid-Barajas airport. To achieve this, it has a noise control system known as SIRMA. This system detects, measures and associates the noise generated by the aircraft when flying over the microphones installed at strategic points.
These measurements are necessary to fulfil the Environmental Impact Statement (EIS). For this reason, the measurement terminals are located at the points with greatest exposure to aeronautical noise, close to the air routes, in order to improve the control and measurement of the degree of noise pollution caused by aeronautical operations in the localities that may be affected.
The information provided by SIRMA is used to ensure that aircraft comply with the established routes and procedures, measuring the noise level registered by the microphones distributed in the vicinity. In the event of non-compliance, an inquiry is carried out and a complaint is filed with the Spanish Airspace Security Agency in case any disciplinary action is required.
The acoustic control is not only limited to aircraft in flight, and noise control is also carried out on the aircraft on the ground, especially during the night, in aircraft apron areas, close to the populations bordering on the airport, such as the case of Aprons: R5 - R6, and South Dock. The system controls aircraft movement in the aforementioned area, both visually and acoustically, is the aircraft voice communications system. The measurement terminals devoted to this operation are equipped with video cameras that enable record of any possible non-compliance, both in real-time and logged.
