  The work addresses the definition of a wavelet that is adapted to analyse a
flexural impulse response. The wavelet gives the opportunity to directly
analyse the dispersion characteristics of a pulse. The aim is to localize a
source or to measure material parameters. An overview of the mathematical
properties of the wavelet is presented. An algorithm to extract the dispersion
characteristics with the use of genetic algorithms is outlined. The application
of the wavelet is shown in an example and experiment.
