In this paper, a time/frequency, multi-look masking model is proposed to predict the detection and discrimination of speech-like stimuli in a variety of noise environments. In the first stage of the model, sound is processed through an auditory front end which includes bandpass filtering, squaring, time windowing, logarithmic compression and additive internal noise. The result is an internal representation of time/frequency "looks" for each sound stimulus. To detect or discriminate a signal in… CONTINUE READING
