Tecniche di indagine acustico-vibrazionale per la determinazione dello stato di degrado di pali in legno

Analysis of acoustic-vibrational response of wooden poles. Non-destructive test consists in measuring mechanical behaviour of poles struck by a hammer. These poles are used for supporting aerial cables and their structural integrity is critical to the safe operation . Vibrational analysis uses a cross correlation alghorithm for optimizing spectral estimation and relative spectral peak identifying. Acoustic analysis adopts machine learning techniques for detecting the status of the poles
