Originální abstrakt

Thermal noise and polarization noise are the main sources of voltage or current fluctuations in piezoceramic samples which are used as acoustic emission sensors or ultrasonic transducers. Noise is related to the energy dissipation and due to that the conductivity is proportional to the imaginary part of susceptibility and to the frequency. The resonance peaks were observed in the frequency range which corresponds with the geometrical dimensions of the sample. Resonance peaks frequencies are influenced by the mechanical damping. In this contribution we will discuss the impact of mechanical damping on the noise characteristics.
