Raising fundamental frequency worsens pitch perception by reducing harmonic resolvability

Evidence

The results of the simulation plotted in Fig. 3 are strongly consistent with Oxenham et al. ( 2011 ). Using a plausible refractory period of 2500 Hz, the simulation is able to extract the TE × TSFperiod even if the TSFperiod are too fast to be correctly encoded. The decrease in performances reported in Oxenham et al. ( 2011 ) when increasing the F0 from 1200 Hz to up to 2000 Hz is also simulated. This decrease is probably explained by a decrease in resolvability (less and less interactions between harmonic components) when increasing the F0. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4613
