Symmetry: Modeling the Effects of Masking Noise, Axial Cueing and Salience
Figure 6
Examples of the model parametrization.
The black curve has all three model components in the denominators, with parameters chosen to for a strong double-corner effect. Green curve: removing the internal noise reduces the threshold at low masker density. Blue curve: removing the divisive inhibition limits the masking effect at high masker density. (Removing the external noise results in a horizontal line, since it is the parameter of the x axis.)
