This document specifies a bending-vibration method based upon resonance curves for determining the flexural complex modulus Ef* of homogeneous plastics and the damping properties of laminated plastics intended for acoustic insulation, for example systems consisting of a metal sheet coated with a damping plastic layer, or sandwich systems consisting of two sheet-metal layers with an intermediate plastic layer.
