Abstract
A method for measuring the physical properties of material comprising the steps of producing a tone burst wave by a tone burst wave oscillator, radiating acoustic energy of the tone burst wave onto an object to be measured to cause vibrations therein, detecting the vibrations as a waveform of an alternating wave at a vibration receiver, obtaining a gradient of a line which connects peaks in a first transitional region of the waveform from which can be determined the physical properties, in particular the energy transfer characteristics and/or restitution coefficient of the object.
