A two-filter model for frequency discrimination . In this paper , we explore a two-filter model , the simplest version of multi-channel models for frequency discrimination of simple tones . According to this model , frequency discrimination is based on a change in the relative output levels of two auditory filters , one centered below and the other above the frequency of the tone . This idea can explain the experimental results that frequency discrimination is relatively unaffected by randomization of stimulus level . Moreover , it suggests a close relationship between the ability of listeners to perform frequency discrimination of simple tones and spectral-shape discrimination of two-tone complexes . The ability of three listeners to perform these two tasks was measured at six frequencies ( from 0.25 to 8 kHz ) . The results from the spectral-shape-discrimination task were used to predict frequency-difference limens . There was a high correlation between obtained and predicted values .
