“…Thus, this fine-structure deficit may be particularly relevant for speech, for which much information is provided in the 1-3 kHz frequency range (French and Steinberg 1947;Ardoint and Lorenzi 2010). This deficit also occurred whether or not noise-exposed fibers had broadened tuning, consistent with recent perceptual evidence that reduced ability to use fine-structure cues is not correlated with reduced frequency selectivity (Santurette and Dau 2007;Lorenzi et al 2009;Strelcyk and Dau 2009). For pitch perception, reduced frequency selectivity is often thought to cause listeners with SNHL to rely more on the less salient envelope cues created by unresolved harmonics than the more salient finestructure cues associated with resolved harmonics (Moore and Carlyon 2005).…”

Recent perceptual studies suggest that listeners with sensorineural hearing loss (SNHL) have a reduced ability to use temporal fine-structure cues, whereas the effects of SNHL on temporal envelope cues are generally thought to be minimal. Several perceptual studies suggest that envelope coding may actually be enhanced following SNHL and that this effect may actually degrade listening in modulated maskers (e.g., competing talkers). The present study examined physiological effects of SNHL on envelope coding in auditory nerve (AN) fibers in relation to fine-structure coding. Responses were compared between anesthetized chinchillas with normal hearing and those with a mild-moderate noise-induced hearing loss. Temporal envelope coding of narrowband-modulated stimuli (sinusoidally amplitude-modulated tones and singleformant stimuli) was quantified with several neural metrics. The relative strength of envelope and finestructure coding was compared using shuffled correlogram analyses. On average, the strength of envelope coding was enhanced in noise-exposed AN fibers. A high degree of enhanced envelope coding was observed in AN fibers with high thresholds and very steep ratelevel functions, which were likely associated with severe outer and inner hair cell damage. Degradation in finestructure coding was observed in that the transition between AN fibers coding primarily fine structure or envelope occurred at lower characteristic frequencies following SNHL. This relative fine-structure degradation occurred despite no degradation in the fundamental ability of AN fibers to encode fine structure and did not depend on reduced frequency selectivity. Overall, these data suggest the need to consider the relative effects of SNHL on envelope and fine-structure coding in evaluating perceptual deficits in temporal processing of complex stimuli.

“…In hearing-impaired (HI) listeners, binaural-pitch perception was found to be either as immediate as in NH listeners or totally absent (Santurette and Dau, 2007). Interestingly, the two subjects who could not perceive binaural pitch at all in the latter study were the ones for whom deficits were likely to be present in central areas of the auditory system.…”

“…The procedure and note frequencies were identical to those described in Santurette and Dau (2007), except that 1-ms ramps were used between intervals, such that the 10-s noise stimulus was perceived as continuous. After one presentation of the stimulus, subjects were asked to verbally report whether something else than noise could be perceived.…”

“…The BP stimulus contained a Huggins' pitch, as this configuration has been reported to evoke the most salient pitch among different types of binaural pitches (Akeroyd et al, 2001;Santurette and Dau, 2007). The pitch in the MP stimulus was created by raising the amplitude of the noise in both ears over a narrow frequency range.…”

“…In a first investigation of the effects of hearing loss on binaural pitch perception, Santurette and Dau (2007) showed that the detection and melody recognition scores of HI listeners with binaural pitch stimuli were not correlated with lowfrequency pure-tone hearing thresholds. Their findings also demonstrated that impaired frequency selectivity affected pitch salience, but that estimates of auditory-filter bandwidths were not correlated with melody recognition abilities with binaural pitch stimuli.…”

The ability of eight normal-hearing listeners and fourteen listeners with sensorineural hearing loss to detect and identify pitch contours was measured for binaural-pitch stimuli and salience-matched monaurally detectable pitches. In an effort to determine whether impaired binaural pitch perception was linked to a specific deficit, the auditory profiles of the individual listeners were characterized using measures of loudness perception, cognitive ability, binaural processing, temporal fine structure processing, and frequency selectivity, in addition to common audiometric measures. Two of the listeners were found not to perceive binaural pitch at all, despite a clear detection of monaural pitch. While both binaural and monaural pitches were detectable by all other listeners, identification scores were significantly lower for binaural than for monaural pitch. A total absence of binaural pitch sensation coexisted with a loss of a binaural signal-detection advantage in noise, without implying reduced cognitive function. Auditory filter bandwidths did not correlate with the difference in pitch identification scores between binaural and monaural pitches. However, subjects with impaired binaural pitch perception showed deficits in temporal fine structure processing. Whether the observed deficits stemmed from peripheral or central mechanisms could not be resolved here, but the present findings may be useful for hearing loss characterization.

Complex broadband sounds are decomposed by the auditory filters into a series of relatively narrowband signals, each of which can be considered as a slowly varying envelope (E) superimposed on a more rapid temporal fine structure (TFS). Both E and TFS information are represented in the timing of neural discharges, although TFS information as defined here depends on phase locking to individual cycles of the stimulus waveform. This paper reviews the role played by TFS in masking, pitch perception, and speech perception and concludes that cues derived from TFS play an important role for all three. TFS may be especially important for the ability to "listen in the dips" of fluctuating background sounds when detecting nonspeech and speech signals. Evidence is reviewed suggesting that cochlear hearing loss reduces the ability to use TFS cues. The perceptual consequences of this, and reasons why it may happen, are discussed.
