“…Although an increase in neural gain -which is thought to compensate for degraded inputs from the auditory periphery -may support the detection of weak signals (Gerken, 1979;Ernst and Moore, 2012;Chambers et al, 2016;Schlittenlacher and Moore, 2016), it may affect how a sound's regularity is represented in cortical structures, in an unhelpful way. This is in line with previous work demonstrating a correlation -with age partialed out -between neural gain enhancements and decreased speech perception performance in the presence of modulated background sound (Millman et al, 2017;Goossens et al, 2018), and with the observation that hearing loss increases the perceived magnitude of low-frequency amplitude modulation in sounds (Moore et al, 1996). This previous work together with the current findings indicate that neural function in central auditory brain structures of older people appears fundamentally altered, including, among others, a change in sensitivity to a sound's temporal regularity in auditory cortex and possibly in higher-level brain regions.…”

“…Furthermore, an increase in neural gain appears to manifest as altered neural adaptation to sounds (Herrmann et al, 2016) and sound statistics (Herrmann et al, 2018), which may impair the flexible adjustment of perceptual systems to different acoustic environments, and may underlie the challenges older people experience with filtering out irrelevant information. Finally, an increase in neural gain in auditory cortex has been related to impaired speech perception (Millman et al, 2017;Goossens et al, 2018). Hence, despite older people showing enhanced responsivity to sound in auditory cortex, acoustic environments may not be represented accurately in the brain.…”

Sensitivity to temporal regularity (e.g., amplitude modulation) is crucial for speech perception.Degradation of the auditory periphery due to aging and hearing loss may lead to an increased response gain in auditory cortex, with potential consequences for the processing of temporal regularities. We used electroencephalography recorded from younger (18-33 years) and older (55-80 years) adults to investigate how aging affects neural gain and the neural sensitivity to amplitude modulation in sounds.Aging was associated with reduced adaptation in auditory cortex, suggesting an age-related gain increase. Consistently, neural synchronization in auditory cortex to a 4-Hz amplitude modulation of a narrow-band noise was enhanced in ~30% of older individuals. Despite enhanced responsivity in auditory cortex, sustained neural activity (likely involving auditory and higher-order brain regions) in response to amplitude modulation was absent in older people. Hence, aging may lead to an overresponsivity to amplitude modulation in auditory cortex, but to a diminished regularity representation in higher-order areas.

“…Auditory information contained in the temporal envelope has been shown to play an important role for speech understanding (Goossens et al, 2018;Rosen, 1992;van Tasell et al, 1987). Physiological measures have shown that the fidelity of speech-envelope representation in neural responses is strongly related to speech perception (Ahissar et al, 2001;Goossens et al, 2018;Peelle et al, 2012).…”

Older adults often experience difficulties understanding speech in adverse listening conditions. These difficulties are partially attributed to auditory temporal-processing deficits associated with aging even in the absence of hearing loss. The aim of this study was to assess the effects of age and hearing loss on temporal envelope processing and speech-on-speech masking. Listeners with normal and near-normal hearing across a wide age range (20 to 66 years) were tested using a series of psychophysical (amplitude-modulation detection, gap detection, and interauralenvelope-phase discrimination), physiological (electroencephalographic envelope-following responses), speech perception (spatial release from masking), and cognitive (processing speed) measures. Results showed that: (i) psychophysical measures of monaural and binaural envelope processing and neural measures of envelope processing are not affected by aging after accounting for audiometric hearing loss, (ii) behavioral gap-detection thresholds decline with age, (iii) aging results in a reduction of spatial release from masking, even as speech intensity is amplified in the region of hearing loss, (iv) aging is associated with poorer measures of cognitive function. Although age significantly contributed to a decline in spatial release from speech-onspeech masking, individual differences in envelope processing and in scores from nonauditory cognitive tests used in this study were not significant predictors of speech performance.

“…Here, linear regressions were conducted to study the neural-behavioral relationship using combined data from young and older adults, as well as young and older adults separately. Furthermore, the present study used an approach that outstripped previous attempts (Presacco et al, 2016a; Goossens et al, 2018). >Presacco et al (2016a) studied the relation between speech-evoked phase-locked responses (FFRs and cortical tracking of speech envelopes) and SPiN performances in both young and older adults, but did not find any significant neural-SPiN correlations.…”

“…Hence neural-SPiN association was not appropriately assessed because acoustic and linguistic properties differed between the two types of background noise (see the discussion in Presacco et al, 2016). Goossens et al, (2018) investigated the relation between subcortical/cortical auditory steady-state responses (ASSRs) and SPiN performances in both normal-hearing and hearing impaired adults across ages and included age itself as an additional predictor when modeling the neural-behavioral relation. This did not fulfil the aim of testing how age-related neural factors contribute to SPiN.…”

11Auditory phase-locked responses are affected by aging and it has been proposed that this increases 12 the challenges experienced during speech perception in noise (SPiN). However, the proposal lacks 13 direct support. This issue was addressed by measuring speech-evoked phase-locked responses at 14 subcortical (frequency-following responses, FFRs) and cortical (theta-band phase-locking, θ-PLV) 15 levels, and studying the relationship between the phase-locked responses and SPiN (word report 16 accuracies in spoken sentences in noise) in adults across a wide age-range (19-75 years old). It was 17 found that: (1) FFR magnitudes declined with age after hearing loss was controlled for; (2) θ-PLV 18 increased with age, suggesting cortical hyperexcitability in audition; (3) SPiN correlated positively 19 with FFR magnitudes obtained in quiet and with θ-PLV obtained in noise, suggesting that impacts 20 of age effects (smaller FFR magnitudes and greater θ-PLV) on SPiN perception differ at subcortical 21 and cortical levels. The current study thus provides evidence for different mechanisms at subcortical 22 and cortical levels by which age affects speech-evoked phase-locked activities and SPiN.23
