The frequencies in Bark were converted to Hz using the formula given in: Zwicker, E. and Terhardt, E.: Analytical expressions for critical-band rate and critical bandwidth as a function of frequency. J. Acoust. Soc. Am. 68, 1523-1525 (1980).
- Masking patterns for narrow-band noise maskers 20-110 dB SPL from Zwicker:

The masking patterns were calculated from excitation patterns of narrow-band noise maskers given in the publication above. The transformation from excitation pattern to masking pattern was done according to: Zwicker, E.: Die elementaren Grundlagen zur Bestimmung der Informationskapazitaet des Gehoers. Acustica 6, 365-381 (1956).

Biphasic leaky integrate-and-fire (BLIF) model for the electrically stimulated auditory nerve fiber by Colin Horne, Christian J. Sumner, and Bernhard U. Seeber. Implemented in Matlab by Marko Takanen, TUM, 2016. A zip file containing the Matlab code for the phenomenological model of the electrically stimulated auditory nerve fiber (ANF).
The model reproduces the ANF response statistics (mean latency, jitter, and firing probability) to both monophasic and biphasic stimuli, in isolation. The response statistics of the model depend on stimulus level and duration of the stimulating pulse, reproducing trends observed in the ANF. The readme-file enclosed in the zip-file provides instructions on how to use the model and the accompanying demo-function.
