ABSTRACT:
A powertrain roughness model is based on a structure comprising an auditory filterbank for spectral decomposition of the powertrain sound signals into a set of critical bandwidth channels, a model for predicting the specific roughness in each critical band channel, and a critical band to wide band converter that combines the specific roughness in each channel into a single roughness value.
