Spectral pitch of pure tones derives from three magnitudes of masking patterns

Evidence

The basic features of the model of spectral pitch of pure tones are explained in Fig. 5.7 which shows the masking pattern of a masking sound M, and the masking pattern of the test tone T, for which the spectral pitch has to be calculated. In addition, the threshold in quiet, THQ, is given as a dashed line. The spectral pitch of the test tone can be described on the basis of the corresponding masking patterns using three magnitudes. … I” is denoted .: MPTM and represents the difference between the masking pattern of the test tone (T) and the masking pattern of the masker (M) at the critical-band rate of the test tone. The second magnitude comprises two components: the component “2a” represents the steepness SMPM of the masking pattern produced by the masking sound in a region 1 Bark below the critical-band rate of the test tone. The other component “2b” represents the steepness of the threshold in quiet, also in a region one critical band below the critical-band rate of the test tone. The third magnitude “3” is denoted .: MTHQ, and represents the difference between the masking pattern of the masker at the critical-band rate of the test tone, and the threshold in quiet at this critical-band rate. — Professor Dr.-Ing.
