“…Bernstein and Oxenham (2003), using a method in which the target harmonic was pulsed on and off, suggested that the upper limit was somewhat higher. However, the results using this method may have been affected by adaptation and release from adaptation (Moore et al, 2009a;Moore et al, 2012). Assuming that no harmonics above the 8th are resolved, the worsening in F0DLs with increasing N from 9 to 11 presumably reflects a decrease in the ability to use TFS information.…”

The dominant region for pitch for complex tones with low fundamental frequency (F0) was investigated. Thresholds for detection of a change in F0 (F0DLs) were measured for a group of harmonics (group B) embedded in a group of fixed non-overlapping harmonics (group A) with the same mean F0. It was assumed that F0DLs would be smallest when the harmonics in group B fell in the dominant region. The rank of the lowest harmonic in group B, N, was varied from 1 to 15. When all components had the same level, F0DLs increased with increasing N, but the increase started at a lower value of N for F0 = 200 Hz than for F0 = 50 or 100 Hz, the opposite of what would be expected if the dominant region corresponds to resolved harmonics. When the component levels followed an equal-loudness contour, F0DLs for F0 = 50 Hz were lowest for N = 1, but overall performance was much worse than for equal-level components, suggesting that the lowest harmonics were masking information from the higher harmonics.

“…It is usually assumed that only harmonics up to about the eighth are resolved [51,52], although the exact upper limit is still debated. Bernstein and Oxenham [53] proposed that harmonics up to about the 10th could be resolved, although the method used by them to determine the limits of resolution has been questioned [54,55].…”

Within the cochlea, broadband sounds like speech and music are filtered into a series of narrowband signals, each with a relatively slowly varying envelope (ENV) imposed on a rapidly oscillating carrier (the temporal fine structure, TFS). Information about ENV and TFS is conveyed in the timing and short-term rate of action potentials in the auditory nerve. This paper describes the role of ENV and TFS information in pitch perception, binaural processing, and the perception of speech in the presence of background sounds. The paper also describes the effects of hearing loss and age on the processing of TFS and ENV information. The monaural and binaural processing of TFS information is adversely affected by both hearing loss and increasing age. The monaural processing of ENV information is little affected by hearing loss or by increasing age. The binaural processing of ENV information deteriorates somewhat with increasing age but is not markedly affected by hearing loss. The reduced TFS processing abilities found for older/hearing-impaired subjects may partially account for the difficulties that such subjects experience in complex listening situations.

“…The resolvability of individual components within a harmonic complex can, to some extent, be measured behaviorally (Moore et al, 1984). But focusing only on resolvability misses the possibility that components may also be hidden within complexes by informational masking; they can be made more salient by mistuning (Moore et al, 1986), or by pulsing of a probe tone (Bernstein and Oxenham, 2003;Moore et al, 2012), in a strategy similar to the one tried in experiment 3 by pulsing a complex probe before a complex mixture. Future research could examine whether the resolvability of the complex mixtures used in the present study, when measured behaviorally in this manner, agrees with predictions of resolvability from rate-place models.…”

Pitch discrimination with mixtures of three concurrent harmonic complexes

In natural listening contexts, especially in music, it is common to hear three or more simultaneous pitches, but few empirical or theoretical studies have addressed how this is achieved. Place and pattern-recognition theories of pitch require at least some harmonics to be spectrally resolved for pitch to be extracted, but it is unclear how often such conditions exist when multiple complex tones are presented together. In three behavioral experiments, mixtures of three concurrent complexes were filtered into a single bandpass spectral region, and the relationship between the fundamental frequencies and spectral region was varied in order to manipulate the extent to which harmonics were resolved either before or after mixing. In experiment 1, listeners discriminated major from minor triads (a difference of 1 semitone in one note of the triad). In experiments 2 and 3, listeners compared the pitch of a probe tone with that of a subsequent target, embedded within two other tones. All three experiments demonstrated above-chance performance, even in conditions where the combinations of harmonic components were unlikely to be resolved after mixing, suggesting that fully resolved harmonics may not be necessary to extract the pitch from multiple simultaneous complexes.
