| Summary: | The EC-funded project COSMA (Community Oriented
Solutions to Minimize aircraft noise Annoyance, 7th
Framework Programme) started in June 2009 with an ambitious,
twofold goal: improve the understanding of the
annoyance induced by aircraft noise on the population
and identify the engineering guidelines to establish appropriate
design strategies and operational procedure to reduce
these effects. The project was conceived within the
context of the X-Noise Collaborative Network, a worldwide
network of experts and institutions committed to the
commercial aviation noise challenge. The COSMA objectives
were addressed using a highly multi-disciplinary approach,
integrating competences pertaining to psychoacoustics,
sound engineering, and aeronautical engineering.
The work of twenty-three research groups from nine
European countries was structured in six, strongly interconnected
work packages. Aim of the present paper is the
review of this cross-disciplinary research from the point
of view of the aircraft designer. The attention is focused
on the Optimisation of Airport Noise Scenarios work package,
where the aeronautical technology contextwas established
in detail and where, eventually, the design criteria
and operational recommendation were defined on the basis
of the outcomes of the annoyance examination experimental
campaign.
