Listeners differentiate pitch height in non-harmonic sounds, implying spectrally weighted cues are essential.

This study investigates how listeners judge pitch height in sounds lacking clear harmonic structures.
Utilized a sinusoidal adjustment task with 48 listeners.
Presented 19 non-harmonic sounds for pitch-height judgments.
Employed linear mixed-effects analyses to interpret data.
Listeners consistently differentiated pitch height across various sounds.
A loudness-weighted spectral centroid significantly predicted perceived pitch height.
Accuracy decreased with increased spectrotemporal variability in sounds.

Velenis et al. (2026) studied this question.
