The frequency limits within which dichotic pitch fusion occurs have been measured as a function of the frequency. The relative frequency differences for the centers of the fusion frequency bands for pure tones coincide with those for binaural diplacusis at corresponding frequencies. A complex (residue) sound fuses only if the fusing conditions for all its individual spectral components are fulfilled. Dichotic fusion of repetition pitch (produced by mixing noise with the same noise, delayed) occurs only if the same noise source is used to produce the signals that are presented to the two ears. Some additional data are presented from experiments with dichotic stimulation with tones of different intensities, where a monotic pitch shift towards the loudest signal is found.Subject Classification: [43]65.54, [43]65.62.
