The authors present an experimental investigation of the temperature and magnetic field dependence of the elastic constants in the two stannide compounds Yb{sub 3}Rh{sub 4}Sn{sub 13} and Ca{sub 3}Rh{sub 4}Sn{sub 13} They find a small elastic softening of the C{sub 44} mode of ca. 2% in the normal state. The temperature dependence of the various elastic modes are quite anomalous in the superconducting state. A comparison of the results is given with corresponding results of CeRu{sub 2}, an amorphous superconductor and other amorphous materials.
