The programs bvas and bamp are used to measure the velocity dispersion and amplitude decay as a function of frequency. These measurements are inverted for material stiffness and damping by Octave procedure cainv3.m according to a method described by Michaels (10). The constitutive model is often referred to as the Kelvin-Voigt solid.
