Environmental noise is closely associated to transport. As a consequence, noise mitigation has mainly driven the research activity in transport acoustics. However, can be applied to research fields other than noise, like safety, diagnosis or signalling, among others.
Air Transport
The vast experience of I2A2 in the environmental or building acoustics, is the reason that entities from the private and public sector have contacted I2A2 searching for research and consultancy to face different challenges regarding noise. Among others, a long term agreement has been dealt with AENA Aeropuertos, encouraging the research on acoustics in the I2A2 Group
Noise
- Modelling of aircraft noise. Software tools are essential for the prediction of noise pollution, and the pursuit of actions to mitigate it. Noise models are essential, as a base to support noise predictions.
- Annoyance studies. Annoyance is one of the effects of noise that has been most extensively studied and evidenced. The search for alternatives to reduce the annoyance is one of the lines of work in which the group is currently focused I2A2.
Instrumentation
- Noise monitoring. Noise monitoring has become an essential tool for the management of environmental noise in different areas, especially in the surrounding of airports. That is the reason why I2A2 has focused on this area, with two different approaches. The first one addresses procedures in measuring and analyzing the uncertainty they produce. The second one, in the development of advanced instruments to cover the deficiencies of traditional instruments. Major advances in this area have to do with the recognition and detection of sounds produced by aircraft, or the detection of sound produced by thurst reverser during landing.

Surface Transport
Noise
- Noise maps. Noise mapping is an essential tool for strategic noise management in transport infrastructures. The creation and implementation of noise models or studies of uncertainty are challenges in the continuous improvement of the processes of making maps.
- Noise inspection of vehicles. The inspection of exhaust noise in vehicles brings up some repeteability and accuracy problems when carried out indoors. By FEM simulation and applying uncertainty propagation procedures, I2A2 seeks to implement solutions to overcome the problems detected in indoor measurements.
- Noise and Vibration Control.
- Economic evaluation of road transport noise.
Instrumentation
- Road safety. Acoustic instrumentation applied to road safety, such as asphalt state detection, or situational awareness improvement.
