We present the results of measurements of the propagation of third sound waves on superfluid {sup 4}He adsorbed to two-dimensional ordered and disordered substrates. In the disordered case we compare the experimental results to theoretical predictions of classical wave localization in such systems and conclude that classical wave localization is present in our system.
