Journal ArticleDOI
The frequency following response (FFR) may reflect pitch-bearing information but is not a direct representation of pitch
TL;DR: The results indicate that the neural responses reflected in the FFR preserve monaural temporal information that may be important for pitch, but provide no evidence for any additional processing over and above that already present in the auditory periphery.
Journal ArticleDOI
The effects of age on temporal fine structure sensitivity in monaural and binaural conditions.
TL;DR: The monaural and binaural TFS tests appear to reflect at least somewhat distinct auditory processes, and there was a significant correlation between age and TFS sensitivity at all frequencies for both T FS tests.
Journal ArticleDOI
Vocoder Simulations Explain Complex Pitch Perception Limitations Experienced by Cochlear Implant Users.
TL;DR: Noise-vocoder simulations are used to explore how many channels, and how little channel interaction, are required to elicit pitch, and suggest that spectrally based complex pitch is unlikely to be generated in implant users without significant changes in the method or site of stimulation.
Journal ArticleDOI
Superoptimal Perceptual Integration Suggests a Place-Based Representation of Pitch at High Frequencies.
TL;DR: By using very high-frequency tones unlikely to be coded via time information, it is discovered that information from the individual harmonics is combined so efficiently that performance exceeds theoretical predictions based on the optimal integration of information from each harmonic.
Journal ArticleDOI
The Perception of Multiple Simultaneous Pitches as a Function of Number of Spectral Channels and Spectral Spread in a Noise-Excited Envelope Vocoder.
TL;DR: Noise-excited envelope vocoders that simulate the limited resolution of CIs are used to explore the perception of multiple pitches presented simultaneously and show that the resolution required for perceiving multiple complex pitches is comparable to that found in a previous study using single complex tones.
