Abstract

The estimation of seismic veloeities in rocks with ultrasonic transmission methods is well known. Our idea is both to apply the tomographic method and to prove the usefulness of spectrometric analysis of sonic signals transmitted through materials of old buildings. The advantage of tomography is that it produces a two-dimensional picture of physical properties inside the rock. Fig. I shows this principle of transmission measurements around the surface.
