Evaluation of a semi-supervised self-adjustment fine-tuning procedure for hearing aids for asymmetrical hearing loss

Objective This study investigated a previously evaluated self-adjustment procedure with respect to its applicability for asymmetrical hearing loss (AHL). Self-adjusted settings were evaluated for speech recognition in noise and sound preference. Design Participants were given the possibility to adjust the left and right hearing aid separately using a two-dimensional user interface. Two different adjustment sequences were tested. Realistic everyday sound scenes in a laboratory environment were presented. The difference between the ears regarding their speech recognition in noise was tested with two spatial conditions, unaided as well as with the prescriptive formula and the self-adjusted setting. Study sample Nineteen experienced hearing aid users (median age 76 years) with different degrees of AHL were invited to participate in this study. Results Participants adjusted a higher gain slope across frequency in the worse ear than in the better one. The two adjustment sequences resulted in significantly different adjustment durations and gain settings. The difference between the ears regarding speech recognition in noise did not change with the self-adjustment. Overall, group-mean effect sizes were small compared to the parameter space. Conclusions The adjustment procedure can be used also by hearing aid users with AHL to find a possibly preferred gain setting.

Factors affecting fat myringoplasty in elderly patients with chronic otitis media: A case control study

BackgroundWe compared and analyzed the surgical results of fat myringoplasty between elderly and young adult patients with chronic otitis media. We also investigated whether underlying diseases and other factors impact the surgical outcome.MethodsWe retrospectively reviewed the data of 141 patients who underwent fat myringoplasty for chronic otitis media for five years. They were compared by age, sex, underlying disease, perforation size, pre- and postoperative pure tone audiometry, postoperative otorrhea, postoperative re-perforation, and cause of re-perforation.ResultPostoperative re-perforation was more common in the elderly group, albeit with no significant difference (p = 0.072). The factors affecting re-perforation were insufficient fat graft (44.4%), postoperative infection (33.3%), and nasal blowing (22.2%). Our findings revealed no significant association between preoperative perforation size and re-perforation (p = 0.391). Additionally, we found no significant relationship between hypertension and re-perforation (p > 0.99), nor between age group and postoperative infection (p = 0.488). Diabetes was also not significant (p = 0.640). Following surgery, both groups exhibited a significant improvement in hearing.ConclusionAlthough age and underlying conditions play significant roles in the healing process, our results suggest that external factors such as infection, nasal blowing, cough, and insufficient grafted fat tissue have a similarly significant impact on surgical outcomes in elderly patients with COM as they do in adults. In conclusion, the decision to perform surgery in elderly patients with COM should be based on a comprehensive assessment of the patient’s overall health status, hearing, use of hearing aids, and the indications for surgery.

Hearing loss in patients with dementia in Saudi Arabia.

To determine the prevalence of hearing loss in patients with dementia, examine the use of hearing aids in those with hearing loss, and ascertain if the cause of hearing loss is central or peripheral in origin. A retrospective cohort study involving 143 patients with dementia which was conducted in Saudi Arabia from 2020 to 2023 in King Abdulaziz Medical City, Riyadh, Saudi Arabia, to determine hearing loss. The study included patients aged ≥60 years who had dementia, hearing loss, and neurological diseases. Those with Parkinson's disease and secondary epilepsy were excluded. Data was analyzed for its demographics, clinical features, predisposing factors, treatment, dementia duration and progression, and hearing loss outcomes. All statistical analyses were performed using IBM's SPSS software, version 29.0.0. Statistical significance was established at a p-value of ≤0.05 and a confidence interval of 95%. The findings indicated that 88.8% of the 143 patients exhibited dementia, with Alzheimer's disease being the most prevalent type. Moreover, 18.2% had hearing issues, and 11.2% had other complaints. Audiometry was performed in 15.4% of the cases. Hearing loss was present in 14.7% of the patients, being primarily bilateral, ranging from mild to severe. This study has clarified the link between hearing loss and dementia onset and has emphasized the need for early evaluation and intervention for individuals with hearing impairment.

Longitudinal follow-up of hearing, speech, and language skills in 6-year-old children with congenital moderate hearing loss

ObjectivesChildren born with moderate hearing loss present with speech and language outcomes at both ends of the spectrum. To explore reasons for this, the objective of this study was to follow up a group of children born with moderate sensorineural hearing loss at 6 years of age (n=7) by investigating their outcomes in hearing, speech, and language development from time point of hearing aid fitting at 6 months. Another objective was to investigate the relationship between earlier outcomes on precursing variables to the current status in auditory, speech and language development. MethodEarlier data from a project with the same participants of auditory variables, speech, and language development were compared to the current study outcomes at 6 years of age. Children in this study performed standardized tests of phonology (SVANTE), expressive vocabulary (BNT), and speech-in-noise test (Hagerman´s sentences). Parents reported on their child´s functional auditory performance in everyday life (PEACH), and demographics and general development (questionnaire). Etiology and frequency of speech and language-directed intervention from time point of diagnosis to 6 years of age were collected through medical journals. ResultsHearing levels were stable over time in all children but one, who had received bilateral cochlear implants. Performance on speech-in-noise testing varied in aided condition (-0.8 to 8, mean 2.65, SD 3.09) and unaided condition (7.2 dB to 21.2 dB, mean 12.06, SD 4.82). Scores on the PEACH indicated further review in four of the seven children. Mean group score on consonant proficiency had increased from 3 to 6 years of age and were within age norms. Vocabulary scores were below the norms of children with typical hearing. Outcomes on vocabulary measures at 2.5 years years showed strong correlations that were significant to scores on the BNT at 6 years of age (r = 0.87, p = 0.05). Correlations between hours of hearing aid use and vocabulary was not significant at 6 years of age. The frequency of intervention sessions in the first 6 years varied between participants (4 to 55, mean 19.1, SD 17.1). ConclusionDespite homogeneous hearing and other background variables in the participants from birth, large individual variations in speech and language outcomes at 6 years of age were found. Considering the many factors involved that impact the development of children with moderate hearing loss, the results suggest that monitoring early precursors in auditory, speech and language development may be helpful in setting commensurate goals for each child. Detecting additional conditions that may pose challenges in future speech and language as early as possible is important. There is ample room for improvement in terms of increasing the frequency of intervention for children with moderate hearing loss and their families.

Hearing Loss, Hearing Aids, and Cognition.

Most observational studies examining the association between hearing loss (HL) and cognitive impairment used subjective measures of hearing and addressed only one dimension of cognition, and very few investigated the potential benefit of hearing aids (HAs). To evaluate objectively measured HL and several dimensions of cognition and estimate the association with HA use. A cross-sectional analysis of the CONSTANCES cohort study, which recruited participants from January 1, 2012, to December 31, 2020, was conducted. Participants were a representative sample of adults (age, 45-69 years) with audiometric data and cognitive evaluation from 21 preventive health centers in France. Data analysis was conducted from April 1 to September 15, 2023. The main exposure was HL, which was defined by a pure-tone average in the best ear higher than 20 dB hearing level for mild loss and 35 dB hearing level for disabling loss. Secondary exposure was self-reported HA use. Cognition was evaluated at study inclusion by a standardized battery of 5 cognitive tests conducted by trained neuropsychologists. A global cognitive score was computed from principal component analysis and global cognitive impairment was defined as having a score less than or equal to the 25th percentile of the distribution. The study population included 62 072 participants with audiometric data (mean [SD] age, 57.4 [7] years; 52% women). Overall, 38% (n = 23 768) had mild HL, 10% (n = 6012) had disabling HL, and 3% (n = 1668) were HA users. In multivariable analyses, mild HL (odds ratio [OR], 1.10; 95% CI, 1.05-1.15) and disabling HL (OR, 1.24; 95% CI, 1.16-1.33) were associated with greater global cognitive impairment. The odds of cognitive impairment did not differ significantly between all participants with HA use and participants with disabling HL without HAs (OR, 0.94; 95% CI, 0.83-1.07), except among participants with depression (OR, 0.62; 95% CI, 0.44-0.88). In this cohort study, an association between the severity of HL and global cognitive impairment was found. The use of HAs was not associated with significantly lower odds of cognitive impairment. The findings suggest that it may be useful to monitor cognitive function in middle-aged individuals with HL.

What is an impact of hearing aids primarily fitted for presbyacusis on quality of life in patients complaining of tinnitus: a pilot study

ObjectiveTo assess the secondary effect of hearing aids primarily fitted for presbyacusis and their impact on the quality of life of patients complaining of tinnitus. DesignPilot case studyStudy sampleAdults with presbyacusis hearing loss were recruited in the Asker ENT clinic in Norway. Twenty consecutive patients were included in the pilot study.MethodsTwenty patients who were diagnosed with presbyacusis and additional tinnitus by the hearing tests (pure tone audiometry and speech audiometry) and medical interviews were recruited for the study. The level of their tinnitus distress was measured by the Tinnitus Handicap Inventory (THI) before and around 2 months after the hearing aid fitting. The results were afterwards statistically analyzed using paired sampled t-tests in Excel.ResultsThe data showed that hearing aids fitted primarily for presbyacusis can improve the quality of life in individuals suffering from tinnitus (p = 0.001504). In our sample, women showed higher levels of complaints about their tinnitus, compared to men. We found that age was an influencing factor on the outcomes of hearing aid usage for both presbyacusis and tinnitus, as people in this study before the age of 75 benefited less than patients above 75 (p = 0.005). All patients with moderate hearing loss in our sample showed significant improvement in their quality of life in regard to their tinnitus complaint, with a statistical value of p = 0.044. Also, patients with the lower levels of THI (slight and mild) were the groups who had the most clinically significant improvements in tinnitus distress. Finally, while analyzing the answers to all the THI questionnaire questions from the patients who did not show improvements in THI scores, a pattern of having trouble sleeping was detected as the most probable factor.ConclusionsThe results showed that hearing aids fitted primarily for presbycusis can have a positive influence on the perception of tinnitus and their quality of life.

Relationships Between Hearing Status, Cognitive Abilities, and Reliance on Visual and Contextual Cues

Objectives: Visual and contextual cues facilitate speech recognition in suboptimal listening conditions (e.g., background noise, hearing loss, hearing aid signal processing). Moreover, successful speech recognition in challenging listening conditions is linked to cognitive abilities such as working memory and fluid intelligence. However, it is unclear which cognitive abilities facilitate the use of visual and contextual cues in individuals with normal hearing and hearing aid users. The first aim was to investigate whether individuals with hearing aid users rely on visual and contextual cues to a higher degree than individuals with normal hearing in a speech-in-noise recognition task. The second aim was to investigate whether working memory and fluid intelligence are associated with the use of visual and contextual cues in these groups. Design: Groups of participants with normal hearing and hearing aid users with bilateral, symmetrical mild to severe sensorineural hearing loss were included (n = 169 per group). The Samuelsson and Rönnberg task was administered to measure speech recognition in speech-shaped noise. The task consists of an equal number of sentences administered in the auditory and audiovisual modalities, as well as without and with contextual cues (visually presented word preceding the sentence, e.g.,: “Restaurant”). The signal to noise ratio was individually set to 1 dB below the level obtained for 50% correct speech recognition in the hearing-in-noise test administered in the auditory modality. The Reading Span test was used to measure working memory capacity and the Raven test was used to measure fluid intelligence. The data were analyzed using linear mixed-effects modeling. Results: Both groups exhibited significantly higher speech recognition performance when visual and contextual cues were available. Although the hearing aid users performed significantly worse compared to those with normal hearing in the auditory modality, both groups reached similar performance levels in the audiovisual modality. In addition, a significant positive relationship was found between the Raven test score and speech recognition performance only for the hearing aid users in the audiovisual modality. There was no significant relationship between Reading Span test score and performance. Conclusions: Both participants with normal hearing and hearing aid users benefitted from contextual cues, regardless of cognitive abilities. The hearing aid users relied on visual cues to compensate for the perceptual difficulties, reaching a similar performance level as the participants with normal hearing when visual cues were available, despite worse performance in the auditory modality. It is important to note that the hearing aid users who had higher fluid intelligence were able to capitalize on visual cues more successfully than those with poorer fluid intelligence, resulting in better speech-in-noise recognition performance.

Preoperative variables affecting outcome of cochlear implant

BackgroundCochlear implants made a great impact in the management of severe-to-profound hearing loss in both children and adults. Its greatest impact is in helping children born with a profound hearing loss and implanted early to attend mainstream education and using spoken language to communicate. However, the final outcome in pediatric implantation is not predictable as there are large number of factors which will affect the outcome of cochlear implantation. Studying these determinants increases the ability of clinicians to offer educated preoperative prognosis and might potentially allow for manipulation of variables in an attempt to achieve the best possible outcome.ObjectiveThe aim of this study was to assess the preoperative factors affecting the audiological, speech, and language outcomes achieved by the recipients of cochlear implants.MethodologyA total of 39 children with severe-to-profound sensory neural hearing loss were implanted with cochlear implants. Children had received their implants before age of 5 years. Tests of receptive, expressive language quotient, aided cortical auditory-evoked potential using speech stimulus, aided free field audiometry, and aided speech reception thresholds were administered. Characteristics of the child and the family (age before implant and duration of implant use, cause of hearing loss, preimplant use of hearing aids and language therapy, and sociodemographic characteristics of their families) were the preoperative variables. These variables were considered predictors of audiological and language outcomes achieved by children and were determined using statistical analysis by univariate and multivariate analyses.ResultsAge of the studied children at time of cochlear implantation was statistically significant predictor for CI outcome as regard receptive language quotient and also for N1 latency. Hearing age of the studied children was a statistically significant predictor for CI outcome as regards P1 latency.ConclusionBased on our findings, two most important factors affecting outcome of cochlear implantation were the age at implantation and the hearing age. Other factors were important but did not affect the outcome significantly.

Age as an important variable that affects auditory and language results after cochlear implant

AbstractCochlear implant (CI) benefits deaf children's speech perception, language development and speech production. Early fitting of an implant results in improved outcomes. Over a period of more than 3 decades, cochlear implantation (CI) is firmly known as safe and effective treatment for children with bilateral severe to profound sensorineural hearing loss (SNHL) who develop minimal or no benefit from conventional hearing aid use. The primary aim of CI is to improve auditory perception of the child and hence the spoken language. The development of functional spoken language would be the major long-term benefits of CI. Children who received a cochlear implant before a real delay in spoken language development (i.e., between 12–16 months) were more able to achieve age-appropriate spoken language. These results strengthen the idea of doing cochlear implantation before 24 months of age, especially for children with a better ear aided pure tone with average thresholds greater than 65 dB prior to surgery.The main aim is to study the effect of age on CI patients results by applying simple questioners on 31 CI children, that are easy to assess the auditory perception and discrimination as an important prerequisite for language development.Results There was an inverse correlation between; age at CI, categories of auditory performance (CAPS), and meaningful auditory integration scale (MAIS) scores. While; there was direct correlation between MAIS & CAPS scores.Conclusions The auditory perception development after CI in children being 3 years old or younger is much better than the older children which would be reflected on their speech perception and acquiring their 1st word and sentence, but language development did not differ between both groups for this period of follow up. With a need of further detailed full language aspects assessment and follow up to ensure these results.

Randomised Controlled Trial for the Evaluation of the Efficacy of the IDA's "Living Well" Online Counselling Tool in First-Time Adult Users with Hearing Loss.

Effective management of hearing loss through the use of modern hearing aids significantly improves communication and the quality of life for individuals experiencing auditory impairment. Complementary counselling of patients with hearing loss who will be fitted with hearing aids for the first time should be evidence-based and adapted to their individual needs. To date, several counselling protocols and tools have been developed. The aim of this randomised controlled trial study was to investigate the efficacy of the application of the IDA's "Living Well" counselling tool in first-time hearing aid users in terms of the degree of their hearing related handicap (using the Hearing Handicap Inventory (HHI)), their communication coping strategies (using the Communication Profile for the Hearing Impaired (CPHI)) and their overall satisfaction of the hearing aids (using a Likert scale). Both groups (the IDA and the control group) were fitted with hearing aids and received counselling for their hearing aids by the same audiologist. The IDA group attended an additional counselling session about communication coping strategies with the use of the "Living Well" tool. Both groups' participants were seen for their hearing aid fittings 4-6 weeks, 3 and 6 months after their fitting when the HHI and the CPHI were measured. Although there was not a statistically significant difference between the two groups for the primary and secondary outcomes, the IDA group did show a more consistent improvement of their HHI score and less frequent use of maladaptive strategies. The "Living Well" counselling tool proved to be a favourably received and helpful counselling tool in first-time hearing aid users.

Music Perception and Music-Related Quality of Life in Adult Cochlear Implant Users: Exploring the Need for Music Rehabilitation.

Cochlear implant (CI) users face difficulties in accurately perceiving basic musical elements such as pitch, melody, and timbre. Music significantly affects the quality of life (QoL) of CI users. Individually and culturally influenced music perception exceeds psychophysical measures in capturing the subjective music enjoyment of CI users. Understanding the music perception, enjoyment, and habits of CI users is crucial for approaches to improve music-related QoL (MuRQoL). Therefore, this study aims to investigate music perception skills, experiences, and participation in music activities in a large group of adult CI users, and to understand the importance of these factors and their impact on QoL of CI users. This study included 214 CI recipients with diverse auditory experiences who were aged between 18 and 65 years and were unilateral, bimodal, or bilateral users for at least 1 year and 193 normal hearing (NH) controls. All participants completed the information forms and the MuRQoL questionnaire. To assess the impact of music on QoL and identify personalized rehabilitation needs, the scores for each question in both parts of the questionnaire were intersected on a matrix. Data were presented in detail for the CI group and compared between CI and NH groups. A statistically significant difference was found between the matched CI and NH groups in favor of the NH group in terms of music perception and music engagement. Participants who received music education at any point in their lives had significantly higher MuRQoL questionnaire scores. There was no significant relationship found between the duration of auditory rehabilitation, pre-CI hearing aid usage, music listening modality, and MuRQoL questionnaire scores. Unilateral CI users had significantly lower scores in music perception and music engagement subsections compared with bimodal and bilateral CI users. Also, it was found that music had a strong negative impact on QoL in 67/214 of the CI users. Although CI users scored significantly lower than NH individuals on the first part of the questionnaire, which asked about musical skills, enjoyment, and participation in musical activities, findings suggest that CI users value music and music enjoyment just as much. The study reveals the influence of factors such as education level, age, music education, type of hearing loss and auditory rehabilitation on music perception, music enjoyment, and participation in music activities through self-report. The results indicate that for many CI users, music has a strong negative impact on QoL, highlighting the need for personalized music interventions, the inclusion of self-report questionnaires, and music perception tests in clinical evaluations.

Leveraging publicly available data to evaluate health reform: establishing a methodology to assess the future impact of over-the-counter hearing aids

Health systems are complex and health reform is uncertain. With an aging global population, chronic health conditions are increasing and have become a priority for policymakers. Hearing loss is the third most common chronic condition among older adults and if left untreated, is associated with poor health and social outcomes. In the US, accessibility and affordability have been significant barriers to hearing aid utilization. Through new reform, over-the-counter (OTC) hearing aids are now available. This study demonstrates how publicly available health data was used to establish a methodology to define, characterize, and analyze the target population of this reform. In this retrospective cross-sectional cohort analysis, data from the National Health Interview Survey (NHIS) was utilized, with a sample that included respondents from the 2021 NHIS Sample Adult Interview. Three hearing aid groups (Active, Potential, General) were defined using questions from the NHIS annual core questionnaire and a baseline population health framework was developed. Binary logistic regression confirmed that the framework sufficiently described two group comparisons (Active-Potential, Active General) and also identified the key determinants of hearing aid utilization. Classification and regression tree (CART) classification amply predicted active hearing aid users and verified the key determinants as important predictors. These findings aligned nicely with literature published before OTC hearing aids were made available, confirming the NHIS to be consistent and representative. Our methodology can be repeated to examine the impact of OTC hearing aids in the post-implementation period and similar approaches should be taken to examine other emerging health reforms.

Hearing Aid Use Trends Among Older Adults by Income and Metropolitan vs Nonmetropolitan Residence

Association of cognitive status, anxiety and depression with hearing loss in the elderly

Objective: Hearing loss is an important problem that is common among older people. Dementia can be defined as a group of disorders that adversely affect memory, thinking function and the ability to perform daily activities. Hearing loss leads to poor quality of life due to loneliness, social isolation, anxiety and susceptibility to depression. Hearing aids are the primary tool used in the management of hearing loss. In this study, we aimed to compare participants with and without hearing loss in terms of cognitive status, depression and anxiety, and to assess the effect of hearing aid use on this process. Method: Between June 2023 and June 2024, 608 patients over the age of 50 who registered at the psychiatric outpatient clinic of Hatay Training and Research Hospital were included in the study. Participants were enrolled if they presented to the Psychiatry outpatient clinic during the selected time interval, were over 50 years of age and agreed to participate in the study. Participants' demographic information, educational status, social information, hearing aid use, minimental score, Beck anxiety score, and geriatric depression score were recorded. Results: When comparing patients with and without hearing loss, statistically significant differences were observed on the Minimental Test, Beck Anxiety Score and Geriatric Depression Score. Conclusion: In this study, a statistically significant relationship was found between hearing loss and cognitive status, depression and anxiety, and it was suggested that the use of hearing aids may be beneficial in terms of preventing the development or slowing the progression of these pathologies.

Association of Intrinsic and Extrinsic Factors on Hearing Aid Servicing, Repair and Users’ Satisfaction During COVID-19 Pandemic

Purpose: Hearing aids (HAs) are electronic devices that provide amplification for individuals with hearing impairment. It requires good maintenance for its trouble-free function, but when HAs are not repaired or serviced on time, it affects communication. In the lockdown period during COVID-19 pandemic, many services were put on hold, including the HA service leading to poor user satisfaction. The study aimed to survey the HA user’s perspectives on its repair, servicing, and satisfaction during COVID-19 using a questionnaire.Methods: Sixty-seven participants reported to the organization during the COVID-19 pandemic for service and repair of HAs participated in the study. All the participants answered a questionnaire which consisted of different variables (extrinsic and intrinsic) affecting HA service, repair and satisfaction.Results: The chi-square test showed that extrinsic factors enjoyed relatively more (14) significant associations than intrinsic ones (8 associations). The lack of transport and non-availability of the HA centres were associated with the significant reason for the delay in the HA being brought for repair.Conclusions: The lockdown due to the COVID-19 pandemic had affected the service, repair and satisfaction of the HA users. The associations among the variables would make the service delivery better during any such pandemics.

The Indian context: an investigative study of assistive listening device usage and experiences among hearing aid users

Background: Assistive Listening Devices (ALDs) augment the functionality of hearing aids and cochlear implants, facilitating enhanced auditory communication for individuals with hearing impairment and potentially improving their life quality. The limited popularity of ALDs within the Indian context necessitates an investigation into the factors influencing their underutilization. Methods: To address this, a survey assessing ALD awareness among Indian hearing aid users with at least one year of device usage was administered using a questionnaire. A total of 42 responses were collected and subjected to descriptive analysis. Results: The findings of the study revealed a predominant willingness among hearing aid users to discover ALDs and their advantages in daily activities. A segment of the cohort was already conversant with ALDs, whereas a minor fraction showed reluctance towards acquiring additional information. Conclusions: The obtained data indicates a requirement for further comprehensive research with a larger pool of data to understand the breadth of user dispositions and the motivation for the indifferent reception of ALDs in the Indian context.

Hearing loss in children with congenital heart disease

Background : Congenital heart disease (CHD) is a dangerous disease, about 50% of deaths will occur in the first month of life. In developed countries almost all types of congenital heart disease have been detected in infancy even at less than 1 month of age, whereas in developing countries many are only detected after the child is older, so in some severe CHD types may have died before being detected. Rubella infection in pregnancy or congenital rubella syndrome (CRS) can cause miscarriage, fetal death, or congenital abnormalities after birth. CRS is characterized by sensorineural hearing loss (SNHL), congenital cataracts or glaucoma, congenital heart disease, and developmental delays. Purpose : This case report was submitted in order to find out how to properly treat patients with hearing loss with sensory deafness and congenital heart disease. Case : Reported a 3-year-old 6-month-old boy diagnosed with very severe degree sensorineural deafness and congenital heart disease based on anamnesis, physical examination and examination of OAE, BERA and ASSR for examination of auditory function) and echocardiography examination for examination of cardiac function. Conclusion : From the history, physical examination and examination of OAE, BERA, ASSR showed patients with very severe sensorineural hearing loss of the left and right ear and congenital heart disease, planned use of hearing aids or cochlear implantation and cardiac consul for CHD treatment.
