THE AUDITORY MODELING TOOLBOX
verhulst2015
Cochlear transmission-line model (improved version)
Usage:
output = verhulst2015(insig,fs,fc,subject,irregularities,sheraPo)
Input parameters:
| insig | Acoustic signal (in Pa). Size: (time x ear). |
| fs | Sampling rate (in Hz). |
| fc_flag | Either a vector with frequencies specifying the probe positions along basilar-membrane sections, or 'all' to probe all 1000 cochlear sections, or 'abr' to probe 401 locations between 112 and 12000 Hz. |
Output parameters:
| V | Velocity of the basilar membrane sections. Size: (time x section x ear). |
| Y | Displacement of the basilar membrane sections. Size: (time x section x ear). |
| E | Sound pressure at the middle ear. |
| CF | Actual center frequencies (in Hz) of the probed basiliar-membrane sections. Size: section. |
Description:
verhulst2015(..) computes the displacement at various sections of the basilar membrane and their velocity of the movement. For more details and parameters, see arg_verhulst2015.
verhulst2015(..) also accepts the following flags among many others:
| 'progress' | Display the calculation progress. Default. |
| 'silent' | No progress display. Opposite of 'progress'. |
| 'no_debug' | No display of debugging information. Default. |
| 'debug' | Display additional debugging information. Opposite of 'no_debug'. |
