Basilar Membrane Excitation Patterns of Rough Sounds Simulated by Means of an Auditory Model

Popis výsledku v původním jazyce

Pure tone can be characterized to sound rough when it is amplitude or frequency modulated. Perception of roughness can also occur when two pure tones differing little in frequency are presented simultaneously. Hydrodynamical cochlear model simulating thebasilar membrane response to sound stimulation is used to get the impression about the basilar membrane excitation patterns caused by rough signals. The model was designed to simulate the real behavior of the cochlea in small mammals, specifically magnitude and phase characteristics of cochlear filters obtained during physiological experiments. Model parameters were then adjusted to simulate the human cochlea. Since it is not possible to conduct in vivo experiments in human cochlea, the model was verified by means of psychophysical experiments. The model can much better than other types of cochlear models (e.g. widely used filterbank models) predict masking experiments with complex sound signals. Perception of roughness is often being
