AB  - A time-frequency auditory model is presented. The model uses the wavelet packet analysis as a preprocessor. The auditory filters are modeled by the rounded exponential filters and the excitation is smoothed by a window function. By comparing time-frequency excitation patterns, it is shown that the change in the time-frequency excitation pattern introduced when a test tone at masked threshold is added to the masker is approximately equal to 7 dB for all types of maskers. The classic detection ratio, therefore, overrates the detection efficiency of the auditory system.
