Modeling roughness perception using a model of cochlear hydrodynamics
Original language description
A term roughness is often used in conjunction with acoustic stimuli whose envelope or frequency rapidly fluctuates in time. It was first introduced by von Helmholtz to describe harsh, rattling and often unpleasant sound sensation usually accompanying these stimuli. This study introduces a computational roughness model which objectively measure an amount of the perceived roughness. The roughness model contains an auditory model transforming the input acoustic stimulus into the simulated neural signal. The perceived roughness is calculated from time envelope of the transformed signal. The predicted roughness is compared with subjective results published in literature. The model successfully predicts roughness of sinusoidaly amplitude modulated (SAM) andsinusoidaly frequency modulated (SFM) tones. It can predict the perceived roughness when relative phase between spectral components of sound stimuli is changed and the perceived roughness of unmodulated bandpass noise.
