We report recent progress on the stability of recovering wave speed from boundary measurements.Two cases are considered: the hyperbolic Dirichlet to Neumann map and the scattering relation.We showed that hyperbolic D-t-N map is not good for the reconstruction,while the scattering relation can be used to reconstruct wave speed in a stable way.
