The goal of the present paper is the experimental detection of noise sources at the leading edge slat in a high-lift device configuration. The noise generation mechanisms are experimentally investigated by means of pressure and velocity measurements in the nearfield and microphone measurements in the far-field. The measurements were conducted in a synchronized manner so as to enable the calculation of the cross-correlation between the acoustic pressure and the near-field fluctuations. The main idea of the concept presented here was to use the coefficient matrix obtained from the aforementioned correlation to identify regularities in the near-field fluctuations that are related to the radiated soundfield.
