Estimates of auditory filter phase response at and below characteristic frequency.
Animal studies in basal cochlear regions have shown that basilar-membrane phase curvature ~or rate of change of group delay with frequency! is negative around characteristic frequency ~CF!, but near zero well below CF. This study examined whether psychophysical masking experiments in humans show the same difference between onand off-CF phase curvature. Masked thresholds were measured for a 2-kH...
متن کاملTowards a measure of auditory-filter phase response.
This study investigates how the phase curvature of the auditory filters varies with center frequency (CF) and level. Harmonic tone complex maskers were used, with component phases adjusted using a variant of an equation proposed by Schroeder [IEEE Trans. Inf. Theory 16, 85-89 (1970)]. In experiment 1, the phase curvature of the masker was varied systematically and sinusoidal signal thresholds w...

متن کاملAuditory filter width affects response magnitude but not frequency specificity in auditory cortex.
Spectral analysis of acoustic stimuli occurs in the auditory periphery (termed frequency selectivity) as well as at the level of auditory cortex (termed frequency specificity). Frequency selectivity is commonly investigated using an auditory filter model, while frequency specificity is often investigated as neural adaptation of the N1 response in electroencephalography (EEG). However, the effec...
متن کاملPsychophysical auditory filter estimates reveal sharper cochlear tuning in musicians.
Musicianship confers enhancements to hearing at nearly all levels of the auditory system from periphery to percept. Musicians' superior psychophysical abilities are particularly evident in spectral discrimination and noise-degraded listening tasks, achieving higher perceptual sensitivity than their nonmusician peers. Greater spectral acuity implies that musicianship may increase auditory filter...
