Applied Acoustics

Description:
Files in the zip folder are organised as follows:
 - Each file refers to a figure in the paper
 - Each line of the figure is reported as a two column matrix in the text file, x values and y values
 - Prior to each matrix three headers lines are displayed reporting labels and legend
