<p class="abstract"><strong>Background:</strong> This study was done to identify the effect that environmental noises have on speech perception of individual with sensorineural hearing loss. The objectives were to develop evidence-based approach to support the need for sophisticated technology and to choose the better one for daily listening purposes of Hearing-Impaired individual to obtain a speech perception score when environmental noises are used as competing signal.</p><p class="abstract"><strong>Methods:</strong> The study was executed in three phases. In phase 1, developing a noise check list and recording the noise levels at different places by using sound level meter, in phase 2, analyzing the recorded noises into spectral and temporal distributions by using software and phase 3, testing the hearing loss individual’s syllables in the presence of recorded noises.  </p><p class="abstract"><strong>Results:</strong> For 0 dB signal to noise ratio (SNR), the mean scores for white noise and temple noise were higher than for other noise types. The bus and auto noise conditions also showed significant difference in values between them. For +10 dB SNR, speech scores obtained for audiometry noise differed statistically from only restaurant and traffic noise. The traffic noise being the poorest differed statistically from all other noise types. On the other end of range, restaurant noise showed highest speech scores.</p><p class="abstract"><strong>Conclusions:</strong> The overall the scores were a lot higher for only restaurant noise and noise of travel in auto. These showed effect of masking release and that hearing impaired are better able to understand conversations in these situations at least.</p>

In this study, the performance of 48 listeners with normal hearing was compared to the performance of 46 listeners with documented hearing loss. Various conditions of directional and omnidirectional hearing aid use were studied. The results indicated that when the noise around a listener was stationary, a first- or second-order directional microphone allowed a group of hearing-impaired listeners with mild-to-moderate, bilateral, sensorineural hearing loss to perform similarly to normal hearing listeners on a speech-in-noise task (i.e., they required the same signal-to-noise ratio to achieve 50% understanding). When the noise source was moving around the listener, only the second-order (three-microphone) system set to an adaptive directional response (where the polar pattern changes due to the change in noise location) allowed a group of hearing-impaired individuals with mild-to-moderate sensorineural hearing loss to perform similarly to young, normal-hearing individuals.

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.

Background and Aim: Sensorineural hearing loss (SNHL) is one of the complications in hemodialysis patients. Vascular access (VA) represents a lifeline for these patients affecting their life quality and clinical outcomes. Arterio­venous fistula is the gold standard of VAs with minor complications and better hemodialysis adequacy. There is no study investigating hearing differences in hemodialysis VAs. Hence, this study aimed to compare SNHL characteristics amongst hemodialysis VAs. Methods: This cross-sectional study conducted on 64 patients aged 18−60 years received regular hemodialysis in 2019. Demographic data and comorbid conditions were recorded based on patients’ case records and electronic databases. After a physical examination, otoscopy, tympa­nometry, and conventional audiometry, patients were divided into fistula (n = 26), permanent catheter (n = 36), and temporary catheter (n = 2) groups according to vascular access type. Results: Prevalence rate of SNHL was 63.89%, 50% and 50% in the permanent catheter, fistula and temporary catheter groups, respectively. Most patients had mild sloping-SNHL in the per­manent catheter and fistula groups as against moderate degree in the other group. There was no significant difference in hearing thresholds, deg­ree and audiogram shape among VA groups. No significant relation was found between age, sex, hemodialysis duration and disease duration with hearing loss in all groups (p > 0.05). Conclusion: More patients had SNHL in per­manent catheter group. Vascular access types, longer duration of hemodialysis and disease dur­ation do not seem to be associated with SNHL. However, further investigation is needed to cla­rify the relationship. Keywords: Sensorineural hearing loss; vascular access; chronic renal failure; hemodialysis

Introduction: As one of the preferred modes of land transportation, the frequency of train services was very high. One of the negative impacts arising from train activity was noise. The high noise intensity of the train causes hearing loss. Method: This study aims to analyze the differences in the incidence of hearing loss in 2 groups of residents in Turirejo Lawang Malang. This research used the observational method and the data were analyzed descriptive qualitative. A total of 20 people were selected as respondents by purposive sampling. Noise intensity was measured by Sound Level Meter and audiometric measurements were examined at SIMA Malang Laboratory. Result and Discussion: The prevalence of sensorineural hearing loss was more common in residents whose homes at 3-7 m away from the railroad tracks. In addition, residents who lived at least 15 years at a distance of 3-7 m also experienced more hearing loss. One cause of hearing loss is due to exposure to high noise and for a long time and will damage the hair cells in the cochlea, causing hearing loss. If noise exposure continues and for a long period of time damage to hair cells will be permanent and cannot return to normal. Conclusion: There needs to be a policy from the government in determining the minimum limit of the distance of the house to the railroad tracks. In addition, it is necessary to install a barrier near people’s homes to reduce noise.

Objective To assess quality of life (QOL) in pediatric patients with sensorineural hearing loss (SNHL) with the Pediatric Quality of Life Inventory 4.0 (PedsQL 4.0) and the Hearing Environments and Reflection on Quality of Life 26 (HEAR-QL-26) and HEAR-QL-28 surveys. Study Design Prospective longitudinal study. Setting Tertiary care center. Subjects and Methods Surveys were administered to patients with SNHL (ages 2-18 years) from July 2016 to December 2018 at a multidisciplinary hearing loss clinic. Patients aged >7 years completed the HEAR-QL-26, HEAR-QL-28, and PedsQL 4.0 self-report tool, while parents completed the PedsQL 4.0 parent proxy report for children aged ≤7 years. Previously published data from children with normal hearing were used for controls. The independent t test was used for analysis. Results In our cohort of 100 patients, the mean age was 7.7 years (SD, 4.5): 62 participants had bilateral SNHL; 63 had mild to moderate SNHL; and 37 had severe to profound SNHL. Sixty-eight patients used a hearing device. Mean (SD) total survey scores for the PedsQL 4.0 (ages 2-7 and 8-18 years), HEAR-QL-26 (ages 7-12 years), and HEAR-QL-28 (ages 13-18 years) were 83.9 (14.0), 79.2 (11.1), 81.2 (9.8), and 77.5 (11.3), respectively. Mean QOL scores for patients with SNHL were significantly lower than those for controls on the basis of previously published normative data ( P < .0001). There was no significant difference in QOL between children with unilateral and bilateral SNHL or between children with SNHL who did and did not require a hearing device. Low statistical power due to small subgroup sizes limited our analysis. Conclusion It is feasible to collect QOL data from children with SNHL in a hearing loss clinic. Children with SNHL had significantly lower scores on validated QOL instruments when compared with peers with normal hearing.

Changes in auditory threshold, psychophysical tuning curves, and speech perception (in both quiet and noise) were monitored over a 3-hr period following the ingestion of glycerol. All listeners had sensorineural hearing loss secondary to Menière's disease. Findings were characterized by large intersubject variability and in general did not show a clear relation between changes in threshold, frequency resolution, and speech perception.

Recent studies have identified sensorineural hearing loss as a possible manifestation of ankylosing spondylitis. We conducted a study of 30 patients with ankylosing spondylitis to characterize their audiologic profile and to correlate their disease activity and functional indices with their hearing thresholds. The study group was made up of 18 men and 12 women, aged 25 to 58 years (mean: 46.5), who were diagnosed with ankylosing spondylitis. We compared their findings with a socially and demographically matched group of 30 healthy controls. All 60 participants underwent an audiologic assessment, consisting of pure-tone audiometry, speech audiometry, and tympanometry. We used validated indices to assess disease activity and functional status, and we compiled information on the time of diagnosis and the types of medications used to treat the ankylosing spondylitis. We found that the average of the mean air-conduction thresholds at 0.5, 1, 2, and 4 kHz in the ankylosing spondylitis group was significantly worse than that of the controls (p = 0.004). A statistically significant difference was observed at frequencies greater than 3 kHz (p < 0.05). A subgroup of case patients who used only a tumor necrosis factor-alpha inhibitor exhibited better hearing thresholds than patients who used other drugs (p = 0.01). Differences in functional and disease activity scores between case patients with and without hearing loss were not statistically significant. We found that patients with ankylosing spondylitis did indeed have a greater prevalence of sensorineural hearing loss but that it was not correlated with either disease activity or functional status.

Consonant recognition was measured as a function of the degree of spectral resolution of the speech stimulus in normally hearing listeners and listeners with moderate sensorineural hearing loss. Previous work (Turner, Souza, and Forget, 1995) has shown that listeners with sensorineural hearing loss could recognize consonants as well as listeners with normal hearing when speech was processed to have only one channel of spectral resolution. The hypothesis tested in the present experiment was that when speech was limited to a small number of spectral channels, both normally hearing and hearing-impaired listeners would continue to perform similarly. As the stimuli were presented with finer degrees of spectral resolution, and the poorer-than-normal spectral resolving abilities of the hearing-impaired listeners became a limiting factor, one would predict that the performance of the hearing-impaired listeners would then become poorer than the normally hearing listeners. Previous research on the frequency-resolution abilities of listeners with mild-to-moderate hearing loss suggests that these listeners have critical bandwidths three to four times larger than do listeners with normal hearing. In the present experiment, speech stimuli were processed to have 1, 2, 4, or 8 channels of spectral information. Results for the 1-channel speech condition were consistent with the previous study in that both groups of listeners performed similarly. However, the hearing-impaired listeners performed more poorly than the normally hearing listeners for all other conditions, including the 2-channel speech condition. These results would appear to contradict the original hypothesis, in that listeners with moderate sensorineural hearing loss would be expected to have at least 2 channels of frequency resolution. One possibility is that the frequency resolution of hearing-impaired listeners may be much poorer than previously estimated; however, a subsequent filtered speech experiment did not support this explanation. The present results do indicate that although listeners with hearing loss are able to use the temporal-envelope information of a single channel in a normal fashion, when given the opportunity to combine information across more than one channel, they show deficient performance.
