“…This suggested that speech perception abilities of older adults even with normal hearing threshold tended to gradually decrease with aging. Age-related decline in speech perception was also reported in previous studies (Goossens et al, 2017;Hoppe et al, 2022), and prior neuroimaging research has revealed that age-related neural disruption may be a hallmark of these speech processing difficulties (Irsik et al, 2021;Tremblay et al, 2021).…”

Healthy aging leads to complex changes in the functional network of speech processing in a noisy environment. The dual‐route neural architecture has been applied to the study of speech processing. Although evidence suggests that senescent increases activity in the brain regions across the dorsal and ventral stream regions to offset reduced periphery, the regulatory mechanism of dual‐route functional networks underlying such compensation remains largely unknown. Here, by utilizing functional near‐infrared spectroscopy (fNIRS), we investigated the compensatory mechanism of the dual‐route functional connectivity, and its relationship with healthy aging by using a speech perception task at varying signal‐to‐noise ratios (SNR) in healthy individuals (young adults, middle‐aged adults, and older adults). Results showed that the speech perception scores showed a significant age‐related decrease with the reduction of the SNR. The analysis results of dual‐route speech processing networks showed that the functional connection of Wernicke's area and homolog Wernicke's area were age‐related increases. Further to clarify the age‐related characteristics of the dual‐route speech processing networks, graph‐theoretical network analysis revealed an age‐related increase in the efficiency of the networks, and the age‐related differences in nodal characteristics were found both in Wernicke's area and homolog Wernicke's area under noise environment. Thus, Wernicke's area might be a key network hub to maintain efficient information transfer across the speech process network with healthy aging. Moreover, older adults would recruit more resources from the homologous Wernicke's area in a noisy environment. The recruitment of the homolog of Wernicke's area might provide a means of compensation for older adults for decoding speech in an adverse listening environment. Together, our results characterized dual‐route speech processing networks at varying noise environments and provided new insight for the compensatory theories of how aging modulates the dual‐route speech processing functional networks.

“…In the previous study [ 14 ], the inclusion criterion was limited to cases with a hearing loss of 80 dB HL or less. In this group, the WRS max is usually greater than zero [ 15 ]. For candidates with a hearing loss greater than 80 dB HL , a WRS max better than zero was observed for 44 of 82 cases (54%).…”

Background If sufficient speech discrimination is no longer achieved with conventional hearing systems, an audiological indication for a cochlear implant (CI) is given. However, there are no established target criteria for CI aftercare with regard to the level of speech comprehension to be achieved. The aim of this study is to validate an existing predictive model for speech comprehension after CI provision. This is applied to different patient groups. Materials and methods The prospective study included 124 postlingually deaf adults. The model is based on preoperative maximum monosyllabic recognition score, aided monosyllabic recognition score at 65 dBSPL, and age the time of implantation. The model was investigated with regard to prediction accuracy for monosyllabic recognition with CI after 6 months. Results Mean speech discrimination improved from 10% with hearing aid to 65% with CI after 6 months, with a statistically significant improvement in 93% of cases. Deterioration of aided unilateral speech discrimination was not observed. The mean prediction error was 11.5 percentage points in the cases with preoperative scores better than zero and 23.2 percentage points in all other cases. Conclusion Cochlear implantation should also be considered in patients with moderately severe to severe hearing loss and insufficient speech discrimination with hearing aids. The model based on preoperatively measured data for predicting speech discrimination with CI can be used in preoperative consultation and in the context of postoperative quality assurance.

“…The first significant deficits were observed in normal-hearing participants between the ages of 40 and 49 years, even in the absence of peripheral hearing loss. Above the age of 40 years, the maximum word recognition score also starts to decline, as observed in a large cohort [ 27 ].…”

Background: Hearing in noise is challenging for cochlear implant users and requires significant listening effort. This study investigated the influence of ForwardFocus and number of maxima of the Advanced Combination Encoder (ACE) strategy, as well as age, on speech recognition threshold and listening effort in noise. Methods: A total of 33 cochlear implant recipients were included (age ≤ 40 years: n = 15, >40 years: n = 18). The Oldenburg Sentence Test was used to measure 50% speech recognition thresholds (SRT50) in fluctuating and stationary noise. Speech was presented frontally, while three frontal or rear noise sources were used, and the number of ACE maxima varied between 8 and 12. Results: ForwardFocus significantly improved the SRT50 when noise was presented from the back, independent of subject age. The use of 12 maxima further improved the SRT50 when ForwardFocus was activated and when noise and speech were presented frontally. Listening effort was significantly worse in the older age group compared to the younger age group and was reduced by ForwardFocus but not by increasing the number of ACE maxima. Conclusion: Forward Focus can improve speech recognition in noisy environments and reduce listening effort, especially in older cochlear implant users.
