Viscoelastic materials are widely used to solve the vibration and noise problems. To apply the well-known damping technologies successfully to the vibration and noise problems, the damping characteristics of the viscoelastic materials applied to the base structures must be thoroughly understood. The objectives of the present study are : 1) to establish the damping measurement technique via modal testing by which the damping characteristics of viscoelastic materials can be measured in the university laboratory environment, and 2) to develop a computer program to draw the reduced-frequency-nomogram by use of restricted number of experimental data, which can be used efficiently for the damping analysis and application.
