Abstract
In order to determine the sound speed of a layer of an unknown material by measurements in the free-field the advantages of the velocity transfer coefficient of the layer is investigated in comparison to the more usual reflection coefficient and transmission coefficient. A few test measurements are presented which show in principal the feasibility of the sound determination using the velocity transfer coefficient.
