On the Differential Threshold of the Periodicity Pitch
The periodicity pitch (frequency of a reference tone of equal pitch sensation) in harmonic line spectra increases linearly with the basic frequency of the spectrum. The just discriminable change in this basic frequency is measured as a function of basic frequency, frequency region of the complex sound, duration of the signal, and sound pressure level. In some cases, especially at low frequencies, this change lies much below the just discriminable change in the frequency of the pure tone which causes the same pitch as the complex tone. Thus it is not the discrimination mechanism in the tone of equal pitch which is of influence in the formation of the threshold of the periodicity pitch. Rather the threshold is the smallest change in the basic frequency which leads to the differential threshold of just any partial of the complex sound.
