Applied Physiological Modelling of Auditory Processes

In order to understand how we process and perceive sound and speech, we need to complement anatophysiological knowledge with psychoacoustical information. However, relating anatomical structures and their physiology to their contribution to auditory perception is a challenging task. Computational models are valuable tools that allow to bridge the gap between the anatophysiological knowledge of the auditory system and the psychoacoustics of sound and speech. In the last decades, physiologically-based models have increased in popularity and gained importance in the field. These simulate as closely as possible the anatomical components and the physiological processes that occur in the auditory system. Recently, Zilany et al. (2014, 2009) published a model of the auditory periphery up to the auditory nerve (AN) level. Its responses have been validated over a wide range of physiological data from literature. In this thesis, we used said model as a front end in the development of different frameworks to study speech intelligibility, spectrotemporal modulation detection, and interaural time difference perception.status: publishe
