Abstract:
A method for acoustic parameters measurement of viscoelastic material, using the directivity pattern of scattering field of spherical sample made by that material, had been presented. Aluminum spheres had been used for verification of the accuracy of this method, and the measurement results of a kind of rubber had been given. It shows that this method can be used to measure parameters of viscoelastic material in sufficient wide frequency range.
