A critical frequency for thermal fluctuations is calculated above which heat transport proceeds by wave propagation rather than by diffusion. This phenomenon should occur in some dielectric solids. It is the analog of second sound in helium II. A macroscopic point of view is used which relies upon a modification in the Fourier heat equation. Some quantitative results are obtained on the magnitude of this modification.
