4.1. General Comments

Note

• Experimental samples of the same size (\(T / CTS\)) of the numerical samples have been selected for comparison.

• The peak pressure coefficients have been evaluated over moving averages of the original signals, with window size described in the plot legends.

• The acquisition frequency of the numerical calculations is significantly higher than that of the experiments, hence the numerical spectra show a higher cut-off.
