Level-induced pitch shift depends on masking height above the quiet threshold

Evidence

As a first example, the pitch shift produced by variations in the level of pure tones will be described by the model of spectral pitch. In this case, the pattern shown in Fig. 5.7 is considerably simplified because only the masking pattern of the test tone (T) has to be considered since no masker (M) is present. … Thus, the pitch shift of a pure tone caused by its level can be calculated on the basis of the height of its masking pattern above absolute threshold, and the steepness of absolute threshold in a region 1 Bark below the critical-band rate of the test tone. — Professor Dr.-Ing.
