Together with Technische Universität Berlin (Germany), Vectoflow GmbH (Germany), USound GmbH (Austria), University Carlos III de Madrid (Spain) and Universitetet i Sørøst-Norge (Norway), SAL is working on the project AEROMIC. The project, which is part of the Horizon 2020 funded Clean Sky 2 Program, aims at developing an innovative sensor technology for aeroacoustic measurements based on high performance MEMS microphones integrated as microphone arrays, and the development of a compact smart sensor surface through the integration of sensors and electronic components using vertical integration technology.

AEROMIC aims to develop two types of new digital MEMS microphones to fulfil the stringent requirements for wind-tunnel tests and flight tests, respectively, and then integrate those MEMS microphones into large arrays for the accurate measurement of unsteady pressure fluctuations underneath the turbulent boundary layer, which can be applied to predict the cabin noise excitation. The project is coordinated by SAL.
