Undertaking long-term acoustic measurements on sites located near an airport is related to a problem of large quantities of recorded data which very often represents information not related to flight operations. In such areas, usually defined as zones of limited use, other sources of noise often exist such as roads or railway lines treated in such context as an acoustic background. Manual verification of such recorded data is a costly and time-consuming process. Automatic differentiation of the tested noise source from background and precise recognition of quantitative impact of aircraft noise on the acoustic climate in a particular area is an important task. This paper presents the idea of a method that can be used for identifying aircraft operations (flights, take-offs, landings) supported by experimental studies carried out with the use of 3D Microflown sound intensity probe and SoundField ST350 ambisonic microphone. The proposed method is based on determining the spatial sound intensity vector in the tested acoustic field during a monitoring timespan. On the grounds of this information, aircraft operations are marked in a continuous record of noise events.
