“…Previous work further shows that individuals show behavioral correlates of memory for random noise or tone structure in sounds even days and weeks after exposure (Agus et al, 2010;Viswanathan et al, 2016;Bianco et al, 2020;Bianco et al, 2023). That the brain responds with similar magnitude to a reoccurring noise snippet following an interruption compared to a snippet that is part of a regular, noninterrupted sequence is consistent with a memory representation for a noise snippet that lasts long once the representation has been established.…”

“…Several previous works have shown that individuals better detect a noise snippet repetition when the snippet that is repeated recurs across trials compared to a snippet that does not recur (Agus et al, 2010; Agus and Pressnitzer, 2013; Andrillon et al, 2015; Andrillon et al, 2017; Dauer et al, 2022). Previous work further shows that individuals show behavioral correlates of memory for random noise or tone structure in sounds even days and weeks after exposure (Agus et al, 2010; Viswanathan et al, 2016; Bianco et al, 2020; Bianco et al, 2023). That the brain responds with similar magnitude to a reoccurring noise snippet following an interruption compared to a snippet that is part of a regular, non-interrupted sequence is consistent with a memory representation for a noise snippet that lasts long once the representation has been established.…”

“…Listeners are more likely to detect the presence of a pattern when the same, compared to a new, noise snippet is used on different trials (Andrillon et al, 2015;Andrillon et al, 2017;Dauer et al, 2022). Individuals further appear to have memory for specific auditory patterns even days and weeks after they have been exposed to them (Agus et al, 2010;Viswanathan et al, 2016;Bianco et al, 2020;Bianco et al, 2023). However, how the brain maintains memory representations for a noise snippet after it has been repeated is unclear.…”

Neural responses to repeated noise structure in sounds are invariant to temporal interruptions

The ability to extract meaning from acoustic environments requires sensitivity to repeating sound structure. Yet, how events that repeat are encoded and maintained in the brain and how the brain responds to events that reoccur at later points in time is not well understood. In two electroencephalography experiments, participants listened to a longer, ongoing white noise sound which comprised shorter, frozen noise snippets that repeated at a regular 2-Hz rate. In several conditions, the snippet repetition discontinued for a brief period after which the noise snippet reoccurred. The experiments aimed to answer whether neural activity becomes entrained by the regular repetition of noise snippets, whether entrained neural activity self-sustains during the discontinuation period, and how the brain responds to a reoccurring noise snippet. Results show that neural activity is entrained by the snippet repetition, but there was no evidence for self-sustained neural activity during the discontinuation period. However, the auditory cortex responded to a reoccurring noise snippet with similar magnitude compared to a noise snippet for which the snippet repetition had not been discontinued. This response invariance was observed for different onset times of the reoccurring noise snippet relative to the previously established regularity. The results thus demonstrate that the auditory cortex sensitively responds to, and thus maintains a neural representation of, previously learned acoustic noise independent of temporal interruptions.

“…To determine that a regular pattern has emerged, the auditory system must maintain the recently encountered information in some form of memory store, compare incoming information to this representation, and detect pattern repetition. This stimulus has been extensively used to study auditory short-term memory and its neural underpinnings ( Barascud et al, 2016 ; Barczak et al, 2018 ; Bianco et al, 2023 , 2020 ; Herrmann et al, 2019 ; Southwell & Chait, 2018 ). An additional task (TP-COMP), using similar stimuli, required active memory maintenance.…”

“…We use a tone pattern detection task (TP-DETECT; Figure 1 ) to tap the automatic aSM components. This paradigm is extensively used to understand low-level aSM ( Barascud et al, 2016 ; Bianco et al, 2020, 2023 ; Herrmann et al, 2021 ; Milne et al, 2021 ; Southwell et al, 2017 ). Short tones forming patterns are presented at time scales resembling those in speech (20-Hz tone presentation rate, 2-Hz pattern rate) ( Rosen, 1992 ).…”

A growing literature is demonstrating a link between working memory (WM) and speech-in-noise (SiN) perception. However, the nature of this correlation and which components of WM might underlie it, are being debated. We investigated how SiN reception links with auditory sensory memory (aSM) – the low-level processes that support the short-term maintenance of temporally unfolding sounds. A large sample of old ( N = 199, 60–79 yo) and young ( N = 149, 20–35 yo) participants was recruited online and performed a coordinate response measure-based speech-in-babble task that taps listeners’ ability to track a speech target in background noise. We used two tasks to investigate implicit and explicit aSM. Both were based on tone patterns overlapping in processing time scales with speech (presentation rate of tones 20 Hz; of patterns 2 Hz). We hypothesised that a link between SiN and aSM may be particularly apparent in older listeners due to age-related reduction in both SiN reception and aSM. We confirmed impaired SiN reception in the older cohort and demonstrated reduced aSM performance in those listeners. However, SiN and aSM did not share variability. Across the two age groups, SiN performance was predicted by a binaural processing test and age. The results suggest that previously observed links between WM and SiN may relate to the executive components and other cognitive demands of the used tasks. This finding helps to constrain the search for the perceptual and cognitive factors that explain individual variability in SiN performance.
