Audio is also an active topic for acousticians in the aircraft manufacturing industry. Typical concerns are sound quality, noise annoyance or realism, in case of flight simulators. Accordingly, sound field reproduction of real flight conditions in aircraft mock-ups is a valuable tool for jury testing, listening test or marketing purposes. Recently, a cabin mock-up was developed to achieve multichannel sound field reproduction. In this paper, acoustic imaging with an 80-channel microphone array is applied to the objective evaluation, in terms of spatial sound accuracy, of sound field reproduction in the mock-up. Two imaging algorithms are tested, compared and discussed with respect to their ability to provide meaningful attributes for an objective evaluation and comparison of sound field reproduction performance of environmental source distributions. General conclusions about the applicability of acoustic imaging and tested algorithms for the spatial quality assessment of spatial reproduction systems are also provided.
