In the present work, the effect of the temperature on Rayleigh velocity VRVR of superconductor material type Bi2212 is studied, focusing on the modelling of both the reflection coefficient RR(θθ) and the acoustic signature VV(zz). Consequently, the study allows us to deduct the velocities of the acoustic waves of surface and volume, following their evolution as functions of temperature. The study is carried out in case of porous and non-porous superconductor material type Bi2212 in a temperature range from 10 to 295 K and with work frequency of 600 MHz. This modelling study is based on experimental results obtained on porous and non-porous Bi2212 superconducting materials in the temperature range of 10 to 295 K at a frequency of 600 MHz.
