Adaptation of residue pitch

Residue pitch was examined by means of adaptation. The monaural perceptibility of a residue pitch was measured before and after exposure to ipsilateral or contralateral adapatation stimuli of variable spectral composition. Several aspects of adaptation were investigated: pitch channel specificity, number of stimulus components necessary to adapt a residue channel, importance of temporal and spectral factors for adaptation, and the relation between pure‐tone and residue pitch. It was found that there are residue‐pitch channels specifically sensitive to the spectral region and ear of presentation of the stimulus. At least two harmonics were necessary to adapt a residue channel, and pitch channels were found to be insensitive to temporal factors. Residue and pure‐tone pitch seemed to be extracted by different mechanisms, haveing independent channels. The data presented augment the understanding of ptich perception and suggest refinements for pitch‐perception models.
