Abstract

The method involves using filters, time blurring (low-pass filtering), level and frequency adjustment. The audio test signal is compared with a reference signal. Both signals or signal pairs are prefiltered and then separated by a filter bank (3) into frequency ranges. The filter bank characteristics and a subsequent time blurring of the filter output signals are used to produce an perceptual representation of the test signal for evaluation. By comparing the audible representations of the test signal and the reference signal after nonlinear conversion, an estimate of the hearing impression is made.
