review text: Rayleigh wave formulation in a half-space exhibiting generalized thermo- elasticity properties of the Green-Lindsay model [\textit{A. E. Green} and \textit{K. A. Lindsay}, J. Elasticity 2, 1-7 (1972)] has been made. The case of Lord and Shulman's generalized thermoelasticity [\textit{H. W. Lord} and \textit{Y. Shulman}, J. Mech. Phys. Solids 15, 299-309 (1967; Zbl 0156.227)] is shown to occur as a special case. Approximations to the frequency equation have been made for different ranges of the parameters involved. In the case of small coupling, a numerical study has been made to show the effect of the relaxation parameters on the amplitude attenuation factor and also on the velocity of propagation.
