This paper focuses on the modal analysis of the lignocelluloses plates using simple but advanced method to determine the damping coefficient and fundamental frequencies of lignocelluloses plates. First it had been measured the physical in terms of geometrical sizes, mass, moisture contents, than it had been analyzed the dynamical behaviour of the plates at free vibrations, using the impact hammer for light structures and a specialized soft to determine the damping coefficient and natural
