  • Absolute pitch precision is roughly ten times that of trained relative-pitch listeners (similarity 0.85)
  • Nerve firing intervals are integer multiples of the stimulus period (similarity 0.82)
  • Neuronal firing thresholds shape which pitch periodicities a system can detect (similarity 0.82)
  • Pitch is perceived from firing intervals even when nerves skip cycles (similarity 0.80)
  • A strictly periodic tone can still be perceived as two distinct notes (similarity 0.79)
  • Hearing thresholds vary individually but share a common perceptual order (similarity 0.79)
  • The brainstem may convert interspike intervals directly into firing rates (similarity 0.79)
  • Hard reeds fix pitch, freeing resonators to shape only harmonics (similarity 0.79)
  • Vibrato produces tremolo when harmonics sweep across resonant peaks (similarity 0.78)
  • Pitch can only be measured relative, not absolutely (similarity 0.78)
  • Pitch can be coded by monotonic firing rate instead of tuned delay circuits (similarity 0.78)
  • Simulated spike trains encode pitch via envelope-fine-structure interaction periodicities (similarity 0.78)
  • A pianoforte with raised dampers can physically re-echo sung vowels via sympathetic resonance (similarity 0.78)

  • A half-wave-rectified-threshold spike model encodes both envelope and fine structure in one mechanism.
  • Absolute pitch precision is roughly ten times that of trained relative-pitch listeners
  • Nerve firing intervals are integer multiples of the stimulus period
  • Phase-locking limits matter far less when envelope-fine-structure interaction encodes pitch
