The first analysis examined the degree to which better-ear PTA4 alone, THS-H alone, and better-ear PTA4 in conjunction with THS-H predicted performance on a speech-in-noise test, the modified rhyme test. Three binomial mixed-effects models were fitted using better-ear PTA4 alone, THS-H alone, and both measures as primary predictors of interest. Age and sex were included as covariates in all models. The models were compared to one another using Chi-square goodness-of-fit tests and the best-fitting model was examined. Data from 5988 SMs were analyzed in the first analysis. The second analysis examined the degree to which better-ear PTA4 alone, THS-H alone, and better-ear PTA4 in conjunction with THS-H predicted two hearing aid-related outcomes: recommendation for hearing aids by a clinician and hearing aid use. Three receiver operating characteristic curves were fit for each question for better-ear PTA4 alone, THS-H alone, and better-ear PTA4 + THS-H. The area under the curve was bootstrapped to generate confidence intervals to compare the three measures. Data from 8001 SMs were analyzed in the second analysis.</p><p><strong>Results: </strong>In the first analysis, all three models explained more variance than chance; however, the better-ear PTA4 + THS-H model was a significantly better fit than either the better-ear PTA4 alone or the THS-H alone models. Significant main effects of better-ear PTA4 and THS-H indicated that proportion correct decreased as better-ear PTA4 and THS-H increased. A significant interaction was observed such that proportion correct decreased more rapidly if both better-ear PTA4 and THS-H were increasing in tandem. In the second analysis, better-ear PTA4 + THS-H showed good predictive discrimination of a prior hearing aid recommendation. For predicting hearing aid use, better-ear PTA4 was the only predictor with an area under the curve bootstrapped confidence interval that overlapped 0.50, indicating better-ear PTA4 alone is a chance predictor for hearing aid use. Both THS-H alone and better-ear PTA4 + THS-H predicted hearing aid use better than chance, but had poor discrimination overall.</p><p><strong>Conclusions: </strong>Adding the THS-H to the better-ear PTA4 improves predictions of speech intelligibility in noise, has good predictive strength for hearing aid recommendations, and predicts hearing aid use better than chance.

The objective of this article is to systematically review the literature regarding ML models that predict functional CI outcomes, defined as sound perception and production.

When surveyed, workers frequently report that worsened work performance while wearing HPDs is one reason why they choose not to wear them. However, there have been few studies to supplement these subjective reports with objective measures. Where they do exist, assessed performance measures have mostly characterized auditory situational awareness in gross terms (e.g., average speech comprehension scores over an entire session).

The commands were presented in background street noise and were heard under either \"No HPD\" or \"HPD\" conditions. In experiment 1, HPD wearing was simulated with a digital filter designed to mimic the attenuation profile of a passive HPD. In experiment 2, actual HPDs were worn by listeners.

However, its neuropathological features can be objectively quantified using electroencephalography (EEG). Despite the existing research, the pathophysiology of tinnitus remains unclear. The objective of this study was to gain a deeper comprehension of the neural mechanisms underlying tinnitus through the comparison of cognitive event-related potentials in patients with tinnitus and healthy controls (HCs). Furthermore, we explored the potential of EEG-derived features as biomarkers for tinnitus using machine learning techniques.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Design: &lt;/strong&gt;Forty-eight participants (24 patients with tinnitus and 24 HCs) underwent comprehensive audiological assessments and EEG recordings. We extracted N2 and P3 components of the midline electrodes using an auditory oddball paradigm, to explore the relationship between tinnitus and cognitive function.

A linear support vector machine classifier was used to distinguish patients with tinnitus from HCs.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The P3 peak amplitudes were significantly diminished in patients with tinnitus at the AFz, Fz, Cz, and Pz electrodes, whereas the N2 peak latencies were significantly delayed at Cz electrode.

Correlation analysis revealed significant associations between the Hospital Anxiety and Depression Scale-Depression scores and N2 source activities at left insula, right insula, and left inferior temporal gyrus.

The unoccupied noise levels and reverberation times were measured in the unoccupied room either directly before or after the group visit.</p><p><strong>Results: </strong>The average SNR encountered by the children in the intervention groups was +13 dB SNR. The detected speech of the attending professionals achieved the +15 dB SNR recommended by the American Speech-Language-Hearing Association in approximately 42% of the time. The unoccupied noise levels were between 29 and 39 dBA, complying with acoustic norms for classroom environments (≤35 dBA, by ANSI/ASA 12.60-2010 Part 1) for six out of seven groups. Reverberation time was between 0.3 and 0.6 sec for all groups, which complies to the acoustic norms for classroom environments for children without HL (0.6 or 0.7 sec, depending on the room size), while only one group complied to the stricter norm for children with HL (0.3 sec).</p><p><strong>Conclusions: </strong>The current findings show characteristics of the auditory environment of a setting that is specifically equipped and designed for groups of children with HL. Maintaining favorable SNRs seems to be the largest challenge to achieve within the constraints of an environment where young children gather, play, and learn. The results underscore the importance of staying attentive to keep spoken language accessible for children with HL in a group setting.</p>","PeriodicalId":55172,"journal":{"name":"Ear and Hearing","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142959024","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}
