Abstract

Objective quality measurement schemes that incorporate properties of the human auditory system. The basilar membrane (BM) acts as a spectrum analyzer, spatially decomposing the signal into frequency components. Filterbanks were used to complementing the linearity of BM. Each filterbank is an implementation or the Equivalent rectangular Bandwidth (ERB), gammachirp function. This filterbank is level-dependent asymmetric compensation filters. And for the validation of the auditory model, we calculate the calculated perceived difference(CPD).
