Noise is considered as the major source of disturbance of the environment. Among the numerous types of aggressive noises supported by the populations, aircraft noise is the most severe (both in level and in spectral content). This program addresses these development of a new concept in active noise control for open space areas (schools, hotels, homes) against aircraft noise. A successful realisation of this program will find many applications in urban areas located near aiports along major flight lanes. This program will be carried out by leading EUROPEAN SMEs SDTES in the PA and electroacoustic domains.
