- An increasing number of industrial applications in e.g. active noise control require measurement, calibration, and field characterisation in acoustic ducts under time-varying (adaptive) conditions. This paper proposes the first method to achieve this through adaptive calibration of a microphone-based method, using dynamic mean flow with a three-microphone method. Several of the techniques and metrics introduced in the paper have been adopted for industrial application to non-invasive inspection of ducts (e.g. see the use of the “wave separation index” on pages 79-81 of https://www.research.manchester.ac.uk/portal/files/83386380/FULL_TEXT.PDF).
