A comparative study of eight human auditory models of monaural processing
This work addresses the need for standardized comparisons among auditory models for researchers in hearing science and audio processing, but it is incremental as it focuses on existing models without introducing new methods.
The study compared eight monaural auditory models from the Auditory Modelling Toolbox to evaluate their processing stages and outputs, providing recommendations for future applications.
A number of auditory models have been developed using diverging approaches, either physiological or perceptual, but they share comparable stages of signal processing, as they are inspired by the same constitutive parts of the auditory system. We compare eight monaural models that are openly accessible in the Auditory Modelling Toolbox. We discuss the considerations required to make the model outputs comparable to each other, as well as the results for the following model processing stages or their equivalents: Outer and middle ear, cochlear filter bank, inner hair cell, auditory nerve synapse, cochlear nucleus, and inferior colliculus. The discussion includes a list of recommendations for future applications of auditory models.
