The role of piezoeffect in generating an electromagnetic response under impact excitation of piezodielectric materials is studied. The presence of piezoelements in these materials is shown to improve the efficiency of mechanoelectric transformations. It is found out that the high-frequency component of the electromagnetic response in a piezomaterial with inclusions undergoes transformations. A change in porosity of piezomaterials is shown to give rise to shifts of major spectral maxima in the electromagnetic response pattern.
