Psychophysical thresholds were measured for 8-16 year-old children with mild-to-moderate sensorineural hearing loss (MMHL; N = 46) on a battery of auditory processing tasks that included measures designed to be predominantly reliant upon frequency selectivity, and sensitivity to temporal fine structure (TFS) or envelope cues. Children with MMHL who wore hearing aids were tested in both unaided and aided conditions, and all were compared to a group of normally hearing (NH) age-matched controls. Children with MMHL performed more poorly than NH controls on tasks considered to be dependent upon frequency selectivity, sensitivity to TFS, and speech discrimination (/bɑ/-/dɑ/), but not on tasks measuring sensitivity to envelope cues. Auditory processing deficits remained regardless of age, were observed in both unaided and aided conditions, and could not be attributed to differences in nonverbal IQ or attention between groups. However, better auditory processing for children with MMHL was predicted by better audiometric thresholds and, for aided tasks only, higher levels of maternal education. These results suggest that, as for adults with MMHL, children with MMHL may show deficits in their frequency selectivity and sensitivity to TFS, but that sensitivity to envelope cues may remain intact.

Children with sensorineural hearing loss show considerable variability in spoken language outcomes. We tested whether specific deficits in supra-threshold auditory perception might contribute to this variability. In a previous study [Halliday, Rosen, Tuomainen, & Calcus, (2019), J. Acoust. Soc. Am, 146, 4299], children with mild-to-moderate sensorineural hearing loss (MMHL) were shown to perform more poorly than normally hearing (NH) controls on measures designed to assess sensitivity to the temporal fine structure (TFS, the rapid oscillations in the amplitude of narrowband signals over short time intervals). However, they performed within normal limits on measures assessing sensitivity to the envelope (E; the slow fluctuations in the overall amplitude). Here, individual differences in unaided sensitivity to TFS accounted for significant variance in the spoken language abilities of children with MMHL, after controlling for nonverbal IQ, family history of language difficulties, and hearing loss severity. Aided sensitivity to TFS and E cues was equally important for children with MMHL, whereas for children with NH, E cues were more important. These findings suggest that deficits in TFS perception may contribute to the variability in spoken language outcomes in children with sensorineural hearing loss.

Objective The efficacy of the Otologics Fully Implantable Hearing Device (MET) was assessed in adult patients with bilateral moderate to severe sensorineural hearing loss. Methods Surgical insertion of this totally implanted system was identical to the Phase I study. A repeated-measures within-subjects design assessed aided sound field thresholds and speech performances with the subject's own, appropriately fit, walk-in hearing aid(s) and the Otologics Fully Implantable Hearing Device. Results Six- and 12-month Phase II data will be presented. Ten patients were implanted and activated as part Phase II clinical trial. Three patients were lost to long term follow-up due to two coil failures and one ossicular abnormality preventing proper device placement. No significant differences between preoperative (AC = 59 dB, BC = 55 dB) and postoperative (AC = 61 dB, BC = 54 dB) unaided pure tone averages were noted (p < 0.05). Pure tone average implant aided thresholds (41 dB) were equivalent to that of walk-in-aided (37 dB) condition with no significant difference (p < 0.05) between patients’ walk-in-aided individual frequency thresholds and implant-aided thresholds. Word recognition scores and hearing in noise scores were similar between the walk-in-aided and for the implant-aided condition. Patient benefit scales will be presented at all end points. Conclusions Results of the Otologics MET Fully Implantable Hearing Device Phase II trial provide evidence that this fully implantable device is a viable alternative to currently available hearing aids in patients with sensorineural hearing loss.

Abstract Till about 15 years ago, the only choice of hearing improvement for moderate sensorineural hearing loss with severe speech discrimination defect was a hearing aid. It was only after Mr. Geoff Ball, an electronic engineer who was suffering from a similar defect, started thinking of an alternative to the conventional hearing aid that the Vibrant Soundbridge came into existence, and with the passage of time the indications for the use of the same have increased.

BACKGROUND Sensorineural hearing loss is the most common sensory deficit among older adults. Some of the psychosocial consequences of this condition include difficulty in understanding speech, depression, and social isolation. Studies have shown that older adults with hearing loss show some age-related cognitive decline. Hearing aids have been proven as successful interventions to alleviate sensorineural hearing loss. In addition to hearing aid use, the positive effects of auditory training—formal listening activities designed to optimize speech perception—are now being documented among adults with hearing loss who use hearing aids, especially new hearing aid users. Auditory training has also been shown to produce prolonged cognitive performance improvements. However, there is still little evidence to support the benefits of simultaneous hearing aid use and individualized face-to-face auditory training on cognitive performance in adults with hearing loss. OBJECTIVE This study will investigate whether using hearing aids for the first time will improve the impact of individualized face-to-face auditory training on cognition, depression, and social interaction for adults with sensorineural hearing loss. The rationale for this study is based on the hypothesis that, in adults with sensorineural hearing loss, using hearing aids for the first time in combination with individualized face-to-face auditory training will be more effective for improving cognition, depressive symptoms, and social interaction rather than auditory training on its own. METHODS This is a crossover trial targeting 40 men and women between 50 and 90 years of age with either mild or moderate symmetric sensorineural hearing loss. Consented, willing participants will be recruited from either an independent living accommodation or via a community database to undergo a 6-month intensive face-to-face auditory training program (active control). Participants will be assigned in random order to receive hearing aid (intervention) for either the first 3 or last 3 months of the 6-month auditory training program. Each participant will be tested at baseline, 3, and 6 months using a neuropsychological battery of computer-based cognitive assessments, together with a depression symptom instrument and a social interaction measure. The primary outcome will be cognitive performance with regard to spatial working memory. Secondary outcome measures include other cognition performance measures, depressive symptoms, social interaction, and hearing satisfaction. RESULTS Data analysis is currently under way and the first results are expected to be submitted for publication in June 2018. CONCLUSIONS Results from the study will inform strategies for aural rehabilitation, hearing aid delivery, and future hearing loss intervention trials.

The article shows that one of the alternative methods of treating moderate to severe sensorineural hearing loss can be the use of an external weak magnetic field. The proposed method is based on the coincidence of the effects caused by the exposure of an external electromagnetic field of certain parameters on the auditory nerve, and natural acoustic exposure. The similarity of reaction allows using of external magnetic fields as an artificial stimulator of the auditory system’s neural part. Induction of applied magnetic fields does not exceed 300 µT, which means that under the current legislation such fields are classified as posing no health hazard. This method was tested at Saint Petersburg Research Institute of Ear, Throat, Nose, and Speech based on relevant Ethics Committee approval and complied with informed consent standards of volunteers. 15 patients aged 18 to 45 with III and IV levels of sensorineural deafness without concomitant pathologies were tested. Threshold pure-tone audiometry was performed on each patient at 500, 1000, 2000, 3000, and 4000 Hz before and after the procedure. The results of the experiments showed that electromagnetic stimulation of auditory neurons allows increasing hearing sensitivity. The proposed procedure may not yield a tangible result in patients with auditory deprivation. Patients with hearing aids showed the most significant results. At the same time, the measurements have shown that the sound thresholds among them became 10 dB lower on the average. The non-invasiveness of the exposure provided additional comfort for the patient.
