With a 4 to 5% annual growth of air traffic in the last years, the reduction of aircraft noise becomes imperative for the social acceptance of air transport growth. These Lecture Series proceedings review the different sources of aircraft noise, how noise source and propagation can be modelled, develop solutions to mitigate noise emissions and shed light on the way humans perceive noise.
The first lecture note gives an introduction to acoustics and aeroacoustics. On a scientific point of view, there is still much missing knowledge. Therefore, a review of the relevant computational methods is given covering the fluid dynamics aspects as well as acoustic emission and propagation.
The specification of the noise sources is then detailed whether it comes from the airframe, the turbomachinery components of the engine or from the engine exhaust jets. Passive and active noise control strategies are presented. It is also important to understand the current policy goals in terms of noise footprint reduction, and the relevant international legislation. Tools that are capable of assessing the impact of noise on the community is presented and the way human beings perceive noise is addressed.
Finally, an overview of research programs will be performed, with emphasis on European funded projects.
