The synchronous use of multiple microphones in a phased array allows for the application of acoustic imaging or beamforming algorithms to estimate the location and strength of sound sources. This method is based on the phase delays between the sound source and each of the individual microphones composing the array. This approach allows for the isolation of different sound sources within a complex system, such as the trailing-edge noise of an airfoil tested in a wind tunnel. By employing state-of-the-art integration techniques, accurate estimations of the sound pressure levels emitted can be obtained, as well as comparative studies within different configurations/noise reduction add-ons.
