Although hearing aids are the conventional management strategy for this condition, the rate of abandonment of these devices is high. Complete abandonment of the device can expose individuals to the negative consequences of untreated hearing loss. Although previous studies have examined the effect of attitudes on hearing aid abandonment, they have not investigated the time over which abandonment occurs. Consequently, previous evidence has not explored whether attitudes toward hearing loss and hearing aids are associated with the speed (i.e., hazard) at which individuals abandon their hearing aids over time. Our primary objective was to determine the effect of attitudes toward hearing loss and hearing aids on both the risk and timing of hearing aid abandonment.

Device abandonment over time was assessed by asking the patients about the specific month of hearing aid abandonment. Attitudes toward hearing loss and hearing aids were measured using the Spanish version of the Attitudes towards Loss of Hearing Questionnaire (S-ALHQ), while changes in participation and withdrawal from social activities were assessed using the Glasgow Benefit Inventory questionnaire.

Cochlear implants (CI) are highly effective, however, outcomes vary widely, and accurately predicting speech perception performance outcomes between patients remains a challenge. This study aims to evaluate the ability of ML to predict speech perception performance among CI recipients at 6-month post-implantation using only preoperative variables on one of the largest CI datasets to date, with an emphasis placed on identification of poor performers.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Design: &lt;/strong&gt;All patients enrolled in the national CI outcome tracking database, HERMES, and the institutional CI registry. Data were split 90/10 training/testing with hyperparameter tuning designed to optimize AUPRC performed during 10-fold cross-validation within 100 iterations. Multiple models were developed to predict final and delta (Δ) in consonant-nucleus-consonant (CNC) words and AzBio sentences at 6-month post-implantation. Two metrics, (1) final performance scores and (2) equally distributed 20th percentile performance ranking were used as primary outcomes. All models were compared with currently used \"gold standard,\" defined as linear or logistic regression models leveraging Lazard features (LF). Final metrics for comparison included mean absolute error (MAE), calibration curves, heat accuracy maps, area under the receiver operating curve (AUROC), and F1 score.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 1877 patients were assessed through an ML pipeline. (1) XGBoost (XGB) predicted CNC with MAE of 17.4% (95% confidence interval [CI]: 17.34 to 17.53%) and AzBio with MAE of 20.39% (95% CI: 20.28 to 20.50%) and consistently outperformed linear regression with LF (CNC MAE 18.36% [95% CI: 18.25 to 18.47]; AzBio 21.62 [95% CI: 21.49 to 21.74]). Although statistically significant, the 1 to 2% boost of performance is clinically insignificant. (2) Predicting quintiles/20th percentile categories for CI performance, XGB outperformed logistic regression (Log-LF) across all metrics. XGB demonstrated superior calibration compared with Log-LF and provided a larger proportion of predicted probabilities predictions at the extremes (e.g., 0.1 or 0.9). XGB outperformed Log-LF predicting ≤40th percentile for CNC (AUROC: 0.708 versus 0.594; precision: 0.708 versus 0.596; F1 score: 0.708 versus 0.592) and AzBio (AUROC: 0.709 versus 0.572; precision: 0.710 versus 0.572; F1 score: 0.709 versus 0.572).

The aim of the present study was to provide insight into how different speech-in-noise outcome measures relate to one another, how they behave under different test conditions, and how researchers or practitioners might go about selecting an outcome measure (or measures) depending on the context and focus of their enquiry.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Design: &lt;/strong&gt;An online speech-in-noise study was conducted using the Labvanced experimental platform. A total of 67 participants (42 who reported having normal hearing, 25 who said they had some degree of hearing loss) completed the Effort Assessment Scale (a self-reported measure of daily-life listening effort), followed by a sentence recognition task in which BKB sentences were presented in speech-shaped noise at signal to noise ratios (SNRs) of -8, -4, 0, +4, +8, and +20 dB. Participants were instructed to listen to each sentence and then repeat aloud what they heard. Responses were recorded through participants' webcams and later independently scored by 2 research assistants. Several outcome measures were used to tap into both accuracy and listening effort. Specifically, we examined: (1) objective intelligibility (percentage of keywords correctly repeated); (2) subjective intelligibility; (3) subjective listening effort; (4) subjective tendency to give up listening; and (5) verbal response time (VRT) extracted from the audio recordings. Data were analyzed using Bayesian statistical methods.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Hearing loss and age were associated with speech-in-noise outcomes. Specifically, we observed lower intelligibility (objective and subjective), higher subjective listening effort, and longer VRT (time to verbal response onset) in hearing-impaired compared with normal-hearing listeners, and reduced objective intelligibility and longer VRT in older compared with younger listeners. When moving from highly favorable to more adverse listening conditions, subjective listening effort was the first measure to show sensitivity to worsening SNR, followed by subjective intelligibility, objective intelligibility, subjective tendency to give up listening, and, finally, VRT.

However, how resources are allocated between hearing and vision has not been determined in patients with partial auditory deprivation. This study aimed to investigate the relationship between functional plasticity of the visual and auditory pathways in patients with congenital single-sided deafness (SSD), a typical partial deprivation condition.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Design: &lt;/strong&gt;The cross-sectional cohort was comprised of 25 patients with congenital SSD (mean age ± SD = 31.6 ± 5.2 years, 13 males) and 25 normal hearing (NH) controls (mean age ± SD = 30.9 ± 7.5 years, 13 males). Both visual-evoked potentials (VEPs) and auditory-evoked potentials (AEPs) were assessed for all participants. For assessment of AEPs, auditory stimuli were presented unilaterally through the hearing ear in the SSD group, while the auditory stimuli were presented unilaterally (left and right) and bilaterally in the NH group. Event-related potential analyses focused on the differences in latency and amplitude of VEPs and AEPs between groups. Dipole source analyses of VEPs and AEPs were implemented to measure the dipole strengths and latencies of the bilateral primary visual and auditory cortex and comparisons were made both within and between groups.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;For VEPs, SSD patients exhibited a greater amplitude and a shorter latency than NH controls. For dipole source analysis of VEPs, no interhemispheric asymmetry or between-group difference was observed. For AEPs, the amplitude of SSD patients was greater than that of NH controls under the monaural condition but did not exceed that evoked by binaural stimuli in NH controls. For dipole source analysis of AEPs, interhemispheric strength asymmetry was observed in NH controls in response to monaural stimuli but was less clear in SSD subjects. Considering the side of deafness, interhemispheric strength asymmetry was hardly observed in left SSD (LSSD) patients, and was also weakened in right SSD (RSSD) patients. The interhemispheric difference index of dipole strength in LSSD patients was significantly lower than that in NH controls in response to right monaural stimuli.

Children who are DHH and who first received hearing habilitation services before 3 years of age from the government-funded national hearing service provider in the states of New South Wales, Victoria, and Southern Queensland in Australia were invited to enroll in the study. At 9 years of age, enrolled children were assessed using standardized measures of language, cognitive abilities, and speech perception. The children also completed questionnaire ratings on their quality of life. Parents provided demographic information about their child, family, and education; and completed ratings on their child's quality of life. Audiological data were retrieved from the client database of the hearing service provider and records held at CI centers. Descriptive statistics were used to report quantitative outcomes. The relationships among demographic characteristics, including age at fitting of HAs or CIs, and children's outcomes were examined using structural equation modeling.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 367 children, 178 (48.5%) girls, completed assessments at age 9.4 (SD = 0.3) years.

The modeling result is consistent with verbal short-term memory having a mediating effect on multiple outcomes. Better verbal short-term memory is significantly associated with no additional disabilities, earlier age at CI activation, use of an oral communication mode in early intervention, and higher maternal education. In turn, verbal short-term memory directly and positively affects speech perception, language, and health-related quality of life. Maternal education directly and positively affects language outcomes, and indirectly via its effects on nonverbal I.Q. and verbal short-term memory.

{"title":"Comparison of LS CE-Chirp and Click Stimuli in Auditory Brainstem Responses in High-Frequency Hearing Loss.","authors":"Uğur Belet, Ateş Mehmet Akşit, Ebru Kösemihal","doi":"10.1097/AUD.0000000000001586","DOIUrl":"10.1097/AUD.0000000000001586","url":null,"abstract":"<p><strong>Objectives: </strong>The auditory brainstem response (ABR) is an evoked potential used to estimate the hearing thresholds and identify potential auditory pathologies. Although a click stimulus is generally used as an auditory stimulus in diagnostics, recent reports show that the Level-Specific CE-Chirp (LS CE-Chirp) stimulus can also be used for clinical diagnosis. In this study, we compared the auditory brainstem test outcomes of the LS CE-Chirp stimulus and the click stimulus in individuals with high-frequency hearing loss (HFHL).</p><p><strong>Design: </strong>Patients with HFHL (n = 30) and individuals with normal hearing (n = 30) were included in the study. Audiometric pure-tone thresholds were determined for all subjects at 250 to 8000 Hz. For individuals with normal hearing, the pure-tone thresholds were required to be ≤20 dB HL for all frequencies. HFHL cases were selected from people with at least 5 years of hunting experience. All subjects were tested with ABR at 80 and 60 dB nHL. The ABR test was performed using click and LS CE-Chirp stimuli at a rate of 11.1/sec. ABR wave I, III, and V peak latencies and I to V interpeak latency values were compared within and among the groups.</p><p><strong>Results: </strong>Longer latency values were obtained with the LS CE-Chirp stimulus at 80 dB nHL intensity and 11.1/sec stimulus frequency than with the click stimulus in the control group. No significant difference was detected between the LS CE-Chirp and click stimuli at the 80 dB nHL intensity level in the HFHL group ( p > 0.005). When the HFHL patients were classified according to the 4000 Hz threshold, the click stimulus was found to be more compatible with the behavioral 4000 Hz threshold.</p><p><strong>Conclusions: </strong>The wave latency values obtained with the LS CE-Chirp stimulus in the HFHL group, unlike with the click stimulation, were less affected by the level of hearing loss in the HFHL group. For this difference to have a diagnostic value, further studies would be needed on patients with different pathologies and hearing loss configurations.</p>","PeriodicalId":55172,"journal":{"name":"Ear and Hearing","volume":" ","pages":"347-352"},"PeriodicalIF":2.6,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142711579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
