Perception of changing sound requires simultaneous time and frequency resolution

Evidence

The results of the simulation plotted in Fig. 2 evidence that, as in Santurette and Dau ( 2011 ), the predicted pitch values are always related to TE × TSFperiod and never related to TEperiod . This is strongly consistent with the results reported by the authors. 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…, 4638 (#corroborates, via linked claim)

The formation of the percept of pitch and improving its precision requires a sample of a signal with non-zero length. In theory, at least two periods of a periodic signal are necessary before the pitch percept can be formed. The minimum length of a tone burst after which a pitch is perceived is shown in Figure 10.3. The dashed line shows the length of two periods of sine signals. The shortest time window required for pitch perception is seen to be between 400 Hz and 6 kHz, where the length is less than 20 ms. The performance of human hearing in pitch perception is remarkable at low frequencies; the required length for a tone burst is only slightly longer than two periods. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1088 (#qualifies, via linked claim)
