The development of Personal aerial vehicles and unmanned aerial vehicles are expected to have a considerable influence on the development of future airspace design around large cities. In the Metropolis project, four different concepts for airspace design are assessed for a (metropolitan) city of the future. The different noise impact on the ground is addressed in this paper. The noise model is based on the maximum allowable source noise levels as proposed by the Federal Aviation Authority, as actual noise data from the considered aircraft is not available. Transmission loss has been modelled using Noise-Power-Distance relations from the Integrated Noise Model. The resulting noise model shows remarkable different noise footprints between the four concepts and between different traffic patterns, which included both converging and diverging flows. The layered airspace structure provided the lowest noise impact on the ground.
