Abstract

Correlations on the state of ceramic plates, that are either intact or cracked, are performed through the data obtained. In the analysis the frequency range of coherence has been identified in the form of the two regions. Low-frequency region is spectral amplitude that is below the threshold defined by the level of coherence about 0.2, which is on the level of little correlation. This region is in the frequency range of approximately 0-28 kHz. In this frequency range a weak correlation between the spectra of solid ceramic plates and cracked ones is observed.
