Single-sided deaf subjects with a cochlear implant (CI) provide the unique opportunity to compare central auditory processing of the electrical input (CI ear) and the acoustic input (normal-hearing, NH, ear) within the same individual. In these individuals, sensory processing differs between their two ears, while cognitive abilities are the same irrespectively of the sensory input. To better understand perceptual-cognitive factors modulating speech intelligibility with a CI, this electroencephalography study examined the central-auditory processing of words, the cognitive abilities, and the speech intelligibility in 10 postlingually single-sided deaf CI users. We found lower hit rates and prolonged response times for word classification during an oddball task for the CI ear when compared with the NH ear. Also, event-related potentials reflecting sensory (N1) and higher-order processing (N2/N4) were prolonged for word classification (targets versus nontargets) with the CI ear compared with the NH ear. Our results suggest that speech processing via the CI ear and the NH ear differs both at sensory (N1) and cognitive (N2/N4) processing stages, thereby affecting the behavioral performance for speech discrimination. These results provide objective evidence for cognition to be a key factor for speech perception under adverse listening conditions, such as the degraded speech signal provided from the CI.

Objective: This blinded, randomized controlled trial assessed the effectiveness of a personalized, spectrally altered music-based sound therapy over 12 months of use. Method: Two groups of participants (n = 50) were randomized to receive either altered or unaltered classical music. The treatment group received classical music that had been modified based on spectral alterations specific to their tinnitus characteristics. Tinnitus and psychological functioning were assessed at baseline and 3, 6, and 12 months after initial testing using self-reports. Participants, investigators and research assistants were blinded from group assignment. Results: Data from 34 participants were analyzed. The treatment group reported significantly lower levels of tinnitus distress (primary outcome, assessed using the Tinnitus Handicap Inventory) than the control group throughout the follow-up period. Among the treatment group, there were statistically significant and clinically meaningful levels of reduction in tinnitus distress, severity, and functional impairment at 3- and 6-month follow-ups, which was sustained at the 12-month follow-up. Conclusion: The personalized music therapy was effective in reducing subjective tinnitus and represents a meaningful advancement in tinnitus intervention.

Objective: To report the hearing results of cochlear implantation simultaneous to vestibular schwannoma (VS) resection by means of a translabyrinthine approach in patients with normal contralateral hearing. Methods: This was a prospective study including adults with sporadic VS. Tumors were resected by means of a modified translabyrinthine approach with preservation of the cochlear nerve. Results: A total of 13 patients underwent cochlear implantation. At 14 months, the mean pure-tone audiogram was 56 dB. The mean speech recognition was 80%. Cochlear implantation provides monaural and binaural benefits in all the conditions tested, including sound localization. Conclusions: Cochlear implantation can be safely performed simultaneously to VS resection with satisfactory hearing results provided that the cochlear nerve is anatomically intact.

Hearing impairment in the elderly is usually treated with conventional hearing aids; however, a large number of older people do not achieve sufficient speech recognition with hearing aids. The aim of the study was to describe speech perception with hearing aids in comparison to pure-tone hearing loss and maximum speech recognition scores for phonemically balanced words. Data from 392 hearing aid users with different degrees of hearing loss were evaluated retrospectively. In particular, pure-tone thresholds, the maximum monosyllabic word score, and the monosyllabic word score in quiet at conversational level with a hearing aid were analysed. The results showed that speech perception scores decline with increasing age. Even when corrected for pure-tone hearing loss, a significant decline in speech recognition scores after the age of 80 years was observed. Regarding the maximum monosyllabic word score, the effect is smaller but still observable; thus, speech recognition with hearing aids is significantly lower for older subjects. This can be attributed partially to the reduction of the information-carrying capacity in this group.

The deteriorating ability to communicate has a negative impact on quality of life in the aging population. Cochlear implantation is increasingly used to treat hearing impairment and to restore the ability to communicate. Here, in a sample of 79 adults (70 years and older), we explored the effect of cochlear implantation on the health-related quality of life via the Nijmegen Cochlear Implant Questionnaire, auditory performance for speech recognition comparing scores on the Freiburg Monosyllabic Test and Oldenburg Inventory and tinnitus-related distress using the German version of the Tinnitus Questionnaire. We observed that the health-related quality of life and auditory performance increased significantly after cochlear implantation for the study cohort. After implantation, tinnitus-related distress declined significantly for the group. Our results support the concept of cochlear implantation treatment positively influencing the quality of life, restoring the auditory performance in older adults and reducing stress related to tinnitus. Importantly, positive effects were seen as early as 6 months after cochlear implantation, corroborating the rationale for cochlear implantation in adults 70 years and older.

A growing interest in cognitive effects associated with speech and hearing processes is spreading throughout the scientific community essentially guided by evidence that central and peripheral hearing loss is associated with cognitive decline. For the present research, 125 participants older than 65 years of age (105 with hearing impairment and 20 with normal hearing) were enrolled, divided into 6 groups according to their degree of hearing loss and assessed to determine the effects of the treatment applied. Patients in our research program routinely undergo an extensive audiological and cognitive evaluation protocol providing results from the Digit Span test, Stroop color-word test, Montreal Cognitive Assessment and Geriatric Depression Scale, before and after rehabilitation. Data analysis was performed for a cross-sectional and longitudinal study of the outcomes for the different treatment groups. Each group demonstrated improvement after auditory rehabilitation or training on short- and long-term memory tasks, level of depression and cognitive status scores. Auditory rehabilitation by cochlear implants or hearing aids is effective also among older adults (median age of 74 years) with different degrees of hearing loss, and enables positive improvements in terms of social isolation, depression and cognitive performance.

The study aim was to determine the benefit of cochlear implantation and hearing aids in older adults diagnosed with hearing loss and to evaluate the index of depression, anxiety and quality of life after such treatments. A retrospective cohort comprised 117 patients older than 65 years and diagnosed with moderate to profound hearing loss who were included and classified into 2 groups (treated vs. non-treated). A battery of tests including auditory (pure-tone average, disyllabic words in quiet at 65 dB SPL) and findings from a series of questions relevant to quality of life were compared between both groups. Auditory outcomes for disyllabic words were 58.21% for the cochlear implant-treated group and 82.8% for the hearing aid-treated group. There was a positive effect on anxiety, depression, health status and quality of life in the cochlear implant group versus the profound hearing loss control group. We conclude that older adults with moderate to profound hearing loss gain benefit from hearing aids or cochlear implants not only in terms of improved hearing function, but also in terms of positive effects on anxiety, depression, health status and quality of life.

The number of cochlear implant (CI) users is increasing annually, resulting in an increase in the workload of implant centers in ongoing patient management and evaluation. Remote testing of speech recognition could be time-saving for both the implant centers as well as the patient. This study addresses two methodological challenges we encountered in the development of a remote speech recognition tool for adult CI users. First, we examined whether speech recognition in noise performance differed when the steady-state masking noise was presented throughout the test (i.e. continuous) instead of the standard clinical use for evaluation where the masking noise stops after each stimulus (i.e. discontinuous). A direct coupling between the audio port of a tablet computer to the accessory input of the sound processor with a personal audio cable was used. The setup was calibrated to facilitate presentation of stimuli at a predefined sound level. Finally, differences in frequency response between the audio cable and microphones were investigated.
