\subsubsection{Signal amplitude}  Signal amplitude (Fig. \ref{fig:fig5}) \ref{fig:fig5} - bottom)  shows a rapid decrease in the pressure range 5-7 MPa and once the phase transtion crossed, its decrease is smoother. This trend is valid for CH sample for both P- and S-wave signal, however, for CA sample, the amplitude decreases steadily and there is any detected transition phase.\\ Being both samples very tight, variations in velocity and signal amplitude are small. Said that, CH sample shows larger sensitivity to CO$_2$ phase change rather than CA sample. This is due to its larger porosity and permeability values (Table 1).
