Recent publications have raised doubts as to whether damage in structures can be detected by the application of frequency analyses. In fact, very often, temperature changes show larger reactions in spectra than any smaller damage. Beside temperature, other environmental influences such as radiation from sunshine create changes in the structural systems that have to be considered.
