# ROENNE2012 - Simulate auditory brainstem responses (ABRs)

## Usage

[waveVamp, waveVlat]  = roenne2012(flag)


## Output parameters

 waveVamp Amplitude of simulated ABR wave V. waveVlat Latency of simulated ABR wave V peak.

## Description

The flag may be one of:

 'plot' Plot the output. See plot_roenne2012. 'no_plot' Do not plot. This is the default. 'fsmod',fsmod Auditory nerve model sampling frequency. Default value is 200000. 'flow',flow Auditory nerve model lowest center frequency. Default value is 100 Hz. 'fhigh',fhigh Auditory nerve model highest center frequency. Default value is 16000 Hz. 'min_modellength',mn Minimum length of modelling measured in ms. Default value is 40.

roenne2012(stim,fsstim,stim_level) returns simulated ABR wave V latency and amplitude. The stimulus stim must be defined in pascals and calibrated so a pure tone stimulus has an RMS value of 1. Transient stimuli (which this model is designed to simulate) has to be calibrated in peSPL acoustically. This is not the same as "just" having a numerical peak to peak value of the same level as the pure tone. For calibrated click, chirps and tone bursts, see roenne2012_click, roenne2012_tonebursts and roenne2012_chirp.

The parameter fsstim gives the sampling frequency of the input stimulus, and stim_level the level. As input is calibrated to an RMS-value of 1, a stimulus level in (pe)SPL has to be set.
