output = exp_lopezpoveda2001(flag)
exp_lopezpoveda2001(flags,... ) reproduces experiments from the Lopez & Poveda (2001) paper.
The following flags can be specified;
'plot' | Plot the output of the experiment. This is the default. |
'no_plot' | Don't plot, only return data. |
'fig2' | Reproduce Fig. 2 from Lopez & Poveda (2001) Fig. 2a represents the outer ear filter - pressure gain (dB) over frequency with data points from Pralong and Carlile (1996). Fig. 2b represents the middle ear filter - stapes velocity at 0dB over frequency in one plot Fig. 2b shows for default \(fs = 22050 Hz\):
The dimensions of the output are: frequency values x data points x figure no. |
'fig2a' | Reproduce just Fig. 2a. |
'fig2b' | Reproduce just Fig. 2b. |
'fig3bc' | Reproduce Fig. 3b and c from Lopez & Poveda (2001). Isointensity response of the linear, nonlinear and summed response of the lopezpoveda2001 filter for an input level of 30dB (fig 3b) and 85dB (fig 3c) SPL The output is the output of the lopezpoveda2001 filter for the different input levels. The dimensions of the output are: input frequency x [frequency values, linear output, nonlinear output, summed lopezpoveda2001 output] x input level. |
'fig3b' | Reproduce just Fig. 3b. |
'fig3c' | Reproduce just fig. 3c. |
'fig4' | Reproduce Fig. 4 from Lopez & Poveda (2001) - pulsation threshold data (just the model results, not the experimental data) The output is the model result for the different parameter sets. The dimensions of the output are: signal level x masker level x signal frequency masker level consists of 4 columns:
