You should only need to directly run the functions and scripts described in 
the file "Figure_Generation.txt". This README file documents some lower level 
functions that were used to generate analysis data used in those functions.

Fig_4_acoustic_paper.m            - described in "Figure_Generation.txt".
acoustic_fig_4.m                  - called by Fig_4_acoustic_paper.m.
acoustic_fig_5.m                  - described in "Figure_Generation.txt".
acoustic_fig_7.m                  - described in "Figure_Generation.txt".
calib_oscilloscope.m              - calibrate measurements acquired on the oscilloscope.
colheader.m                       - read in and parse the column header description.
countlines.m                      - count the number of lines in a file.
fileheader.m                      - read in and parse the file header.
fitted_line.m                     - draw a fitted line.
get_spe_format.m                  - lookup the format for an oscilloscope file.
kb_moore_1991.m                   - determine kb fit from Moore 1991 paper.
kb_standard.m                     - determine kb fit for foam standard.
low_freq_amplitude.m              - described in "Figure_Generation.txt".
mic_multiplier.m                  - Determine the ratio of the input voltage from the signal generator with the output voltage from the microphone.
mic_timeseries_lab_lowf_1.m       - lookup amplitude data for 1st grouping of data runs.
mic_timeseries_lab_lowf_1b.m      - lookup amplitude data for 2nd grouping of data runs.
mic_timeseries_lab_lowf_phase_1.m - lookup phase shift for 1st grouping of data runs.
read_mic.m                        - read data file generated by the oscilloscope.
read_mic_timeseries_lab.m         - driver to read data file generated by the oscilloscope.
set_plot_attributes.m             - set plot font size attributes.
signal_freq_lab.m                 - foam type and frequency applied for 1st data group.
signal_freq_lab_2.m               - foam type and frequency applied for 2nd data group.
signal_freq_lab_3.m               - foam type and frequency applied for 3rd data group.
sine_fit.m                        - fit a sine curve to frequency data.
slope_intercept.m                 - determine slope and intercept of a line.
strsplit.m                        - split a string. This third-party function was removed from the distribution because it is now available in MATLAB v2017a.
