Zwicker tone pitch sits about 10-20 percent above the notch’s lower edge frequency

Evidence

In stage I, in most cases, the adjusted frequency of the matched sinusoid increased with increase in LEF and was a factor of 1.1-1.2 above the LEF. Two of the subjects reliably matched higher frequencies (factor of 1.3-1.4 above the LEF) in two or three LEF conditions, leading to functions where the matched frequency sometimes did not increase with increase in LEF. For the present purposes, these cases were excluded from further analysis of stage II data, as they could be due to spontaneous OAEs that became audible after listening to the notched noise (Krump 1993 ; Wiegrebe et al. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5405
