 To reduce the aircraft noise while at the same time making this noise more pleasant, in particular for those who live near airports : this is the direction that the aeronautics industry is taking, through the development of a number of national and European projects.... Once the results are obtained, the engineers would like to use them to construct a what the European project refers to as a " Virtual Resident ", " in other words a kind of transfer function enabling one to assess the average reaction to new aircraft noise ", he notes....
