  • Aircraft Sound Diagnostic Method and Device
    Publication number: 20240118172
    Abstract: An aircraft sound diagnostic method includes a step of measurement of acoustic signals by a plurality of microphones mounted at different positions inside the aircraft, a step of recording of the measured acoustic signals, a computation step which generates a sound mapping on the basis of the measured acoustic signals, a step of comparison of the sound mapping and a reference mapping and a step of transmission of the comparison to a user device. The method makes it possible to track the trending of an abnormal noise or of an abnormal noise level and assist in determining the context thereof. An aircraft sound diagnostic device for implementing the method is also described.
