The aim of the paper is to show how the electrical noise of piezoelectric sensor can be modeled. The calculation of noise spectral density given by geometry and material is required for the design of new sensors. The high sensitivity with wide bandwidth sensors are applied in non-destructive testing (NDT). The higher signal to noise ratio is used for further signal processing and interpretation. The sensitivity of piezoceramic sensors demands to minimize their noise. For simplicity, only the piezoceramic part of sensor was under study. We investigated samples with the same geometry and material properties. The numerical results are compared with experimental results and good agreement was obtained.
