A method of controlling a wind turbine comprising a nacelle (3), and a rotary assembly (16) rotating about an axis (A2) with respect to the nacelle (3); the method comprising the steps of: acquiring an acoustic signal (SA); acquiring the current values of at least one operating parameter (1PO; 2PO); comparing the acquired acoustic signal (SA) with a reference acoustic signal (SAR) or a predefined threshold value associated with the acquired current values of the at least one operating parameter (1PO; 2P0); and determining any difference between the acquired acoustic signal (SA) and the reference acoustic signal (SAR) or the predefined threshold value. |
