During development of various resonance systems - screens, acoustic boards, musical instruments parts, etc. it is important to obtain proper amplitude-frequency characteristic. In addition, in examination of wood and its articles it is necessary to evaluate the vibrations of viscous elastic timber structures. Resonance vibrations of different types of acoustic wood boards are investigated in the paper. Amplitude-frequency characteristic, fundamental modes of vibration and coefficient of damping in a wide frequency range are estimated. The relationships between perforation of acoustic boards and parameters of vibroacoustic processes are determined
