Background: Hearing loss is a significant global issue. Individuals affected by this condition face numerous challenges in their daily lives, including difficulties in communication, social isolation, and a diminished quality of life. Thus, early diagnosis and prompt initiation of usage of hearing aids are crucial to mitigate the adverse effects of hearing loss.Purpose: This study aimed to examine the amount of time it takes for an individual to obtain hearing aids after a diagnosis of hearing loss. In addition, it attempted to identify factors that affect individuals in this process.Research Design: This was a cross-sectional survey study.Study Sample: The study comprised 150 individuals who were using hearing aids and were aged 18 years and over. There was an equal distribution of 75 females and 75 males.Data Collection and Analysis: A 23-item questionnaire was given to the participants in order to evaluate the factors that affected the participants with hearing loss in the process of obtaining hearing aids. In addition to this, the date of the hearing loss diagnosis and the date of the hearing aid purchase were calculated. Statistical analyses were made between calculated time and demographic information as well as the survey questions.Results: A significant association was observed between the time of purchasing hearing aids and the deterioration in social relations or fear of exclusion from society (p < 0.05). Furthermore, a significant correlation was found between the time of purchasing hearing aids and the individual’s educational level. Specifically, differences were noted in the purchase time for hearing aids between high school graduates and primary school graduates (p < 0.05). Additionally, the average duration between the diagnosis of hearing loss and the purchase of hearing aids was found to be 3 years.Conclusions: We observed that individuals with hearing loss tend to delay the purchase of hearing aids, and various factors influence this decision. These findings highlight the importance of implementing interventions aimed at facilitating earlier access to hearing aids, thus reducing the negative effects associated with untreated hearing loss.

Background: The behavioral investigation of compressive nonlinearity (CNL) can be achieved by comparing the growth of forward masking (FM) between on-frequency and off-frequency maskers. Because the off-frequency masker exhibits linear behavior at the characteristic frequency whereas the on-frequency masker functions nonlinearly, comparing the experimental outcomes using scalp-recorded auditory brainstem response (ABR) measures provides an objective estimation of auditory physiology.Purpose: The study aimed to examine CNL using ABR parameters, such as Vth peak latency or amplitude, using probe stimuli frequencies ranging from 0.5–4 kilohertz (kHz), which employs both on- and off-frequency FM methods.Research Design: An experimental within-group research design was adopted for the study.Study Sample: The study was conducted in 31 healthy individuals aged 18–45 years (mean age of 27.88 ± 8.589 years).Data Collection and Analysis: The ABR was recorded employing a tone-on-tone FM paradigm for probe stimuli frequencies ranging from 0.5–4 kHz. The experiment was done under unmasked and forward-masked conditions (on- and off-frequency FM with varying masker intensity from 50–80 decibels [dB] sound pressure level [SPL]). The data for latency and amplitude were statistically analyzed using one-way repeated measures analysis of variance (RM-ANOVA), two-way RM-ANOVA, and Bonferroni post hoc tests between and within different probe stimuli in different conditions. Further, a paired t test compared the slope across FM conditions.Results: A gradual shift in Vth peak latency and a reduction in response amplitude was observed in proportion to the increase in masker intensity for both masking conditions across all probe stimuli, with a more pronounced shift in on-frequency FM. However, no significant difference in latency was found between the masker intensities of 60–70 dB SPL in either masking condition. Additionally, the growth of masking showed a steep slope in the on-frequency FM with a smaller R² value.Conclusions: Objective electrophysiologic measures are instrumental in accurately estimating CNL because these measures provide robust, efficient, and reliable insights into the intricate functioning of the auditory system without reliance on a subjective behavioral response.
背景:压缩非线性(CNL)的行为研究可以通过比较前向掩蔽(FM)在频率和频率掩蔽之间的增长来实现。由于低频掩蔽器在特征频率上表现为线性行为,而低频掩蔽器在特征频率上表现为非线性行为,因此使用头皮记录的听觉脑干反应(ABR)测量方法比较实验结果可以客观地估计听觉生理。目的:该研究旨在使用ABR参数(如Vth峰潜伏期或幅度)检查CNL,使用0.5–;4千赫兹(kHz)的探针刺激频率,采用频上和频下调频方法。研究设计:本研究采用实验组内研究设计。研究样本:研究对象为31名年龄在18–;45岁(平均年龄27.88 ±;& # 8201; 8.589年)。数据收集和分析:ABR记录采用单音调频模式,探针刺激频率范围为0.5–4 kHz。实验在无掩模和前掩模条件下进行(掩模强度从50–;80分贝声压级[SPL]不等的开频和低频调频)。潜伏期和振幅数据采用不同条件下不同探针刺激之间和内部的单向重复测量方差分析(RM-ANOVA)、双向RM-ANOVA和Bonferroni事后检验进行统计学分析。此外,配对t检验比较了不同调频条件下的斜率。结果:在所有探针刺激中,在两种掩蔽条件下,Vth峰潜伏期的逐渐变化和响应幅度的减少与掩蔽强度的增加成正比,其中频调频的变化更为明显。然而,在两种掩蔽条件下,60–;70 dB SPL掩蔽强度之间的延迟没有显著差异。此外,掩模的增长在频域调频中表现出陡峭的斜率,且R²值较小。结论:客观电生理测量有助于准确估计CNL,因为这些测量为听觉系统的复杂功能提供了强大、高效和可靠的见解,而不依赖于主观行为反应。

Background: The Tracking of Noise Tolerance (TNT) test instructs listeners to set the background noise to a level that they can tolerate while still understanding >90 percent of speech. It is unclear whether listeners follow the 90 percent intelligibility criterion, however.Purpose: To measure objective and subjective intelligibility of TNT speech materials presented with background noise at signal-to-noise ratios (SNRs) experienced by listeners during the TNT test.Research Design: Single-blind within-subjects design.Study Sample: Twenty-four older listeners with a four-frequency pure-tone average (4PTA) ≤20 dB HL (reference hearing [RH]) and 17 listeners with hearing impairment (HI) of sensorineural origin comprised the sample.Data Collection and Analysis: All participants were tested unaided, and listeners with HI were also tested while aided. Listeners performed the TNT test at 75 and 82 dB sound pressure level (SPL) speech levels. Then, listeners completed the objective–subjective intelligibility difference (OSID) test at the same speech levels across five SNRs to generate objective and subjective speech intelligibility performance intensity (P-I) functions. Next, speech intelligibility was estimated to determine the average TNT noise level and the peaks and valleys of TNT tracings using the individualized P-I functions.Results: Subjective intelligibility ranged between 81 and 90 percent at noise valleys (TNTValley,SUB) and between 30 and 45 percent at noise peaks (TNTPeak,SUB), with the average intelligibility (TNTAve,SUB) between 58 and 69 percent. Objective intelligibility was similar to subjective intelligibility in listeners with RH. For unaided listeners with HI, objective intelligibility across TNT indices was 12 to 18 percent poorer than subjective intelligibility. Objective and subjective intelligibility were within 1 to 8 percent for aided listeners with HI. Except for aided listeners with HI at 75 dB SPL, the TNTValley,SUB was not significantly different from 90 percent. Speech intelligibility (both subjective and objective) measured at the TNTAve and TNTPeak were statistically different from 90 percent.Conclusions: Listeners generally followed the TNT instructions and achieved perceived (i.e., subjective) intelligibility of approximately 90 percent at the TNT valleys. They likely judged the TNT peaks based on other criteria (e.g., loudness) as reflected by the <50 percent subjective intelligibility. These results suggest that TNT informs the clinicians of the SNR that a listener needs to support various degrees of subjective intelligibility.
背景:噪音容忍度跟踪(TNT)测试指导听众将背景噪音设置为他们可以忍受的水平,同时仍然能够理解90%的语音。然而,目前尚不清楚听众是否遵循90%的可理解性标准。目的:以听者在TNT测试中体验到的信噪比(SNRs)衡量背景噪声下TNT语音材料的客观和主观可理解度。研究设计:单盲受试者设计。研究样本:24名四频纯音平均(4PTA) ≤20 dB HL(参考听力[RH])的老年听众和17名感音神经源性听力障碍(HI)听众组成样本。数据收集和分析:所有的参与者都在没有辅助的情况下进行测试,患有HI的听众也在有辅助的情况下进行测试。听众在75分贝和82分贝声压级(SPL)下进行TNT测试。然后,听者在5个信噪比的相同语音水平上完成客观-主观可理解度差异(OSID)测试,生成客观和主观语音可理解度表现强度(P-I)函数。接下来,使用个性化P-I函数估计语音可理解度以确定TNT平均噪声水平和TNT跟踪的峰谷。结果:主观可理解度在噪声谷(TNTValley,SUB)的81 - 90%之间,在噪声峰(TNTPeak,SUB)的30 - 45%之间,平均可理解度(TNTAve,SUB)在58% - 69%之间。RH听者的客观可理解性与主观可理解性相似。对于HI的独立听者,TNT指数的客观可理解性比主观可理解性差12 - 18%。患有HI的辅助听者的客观和主观可理解性在1%到8%之间。除了75 dB SPL的HI辅助听众,TNTValley,SUB与90%没有显着差异。在TNTAve和TNTPeak上测量的语音可理解性(主观和客观)在统计上不同于90%。结论:听众普遍遵循TNT指令,并在TNT谷区达到约90%的感知(即主观)可理解性。他们可能根据其他标准(例如,响度)来判断TNT峰值,这反映在 60%;50%的主观可理解度上。这些结果表明,TNT告诉临床医生听者需要支持不同程度的主观可理解性的信噪比。

Purpose: Saccadometry is an advanced ocular motor test that allows functional assessment of the various brain regions and circuits involved in the generation of accurate saccadic eye movements. Recently, some manufacturers have included the saccadometry test in the videonystagmography (VNG) test battery. This study aimed to evaluate the test–retest reliability of the saccadometry test, which is part of the VNG test battery.Methods: Thirty-five healthy participants (mean age ± standard deviation = 24.66 ± 4.4 years; 26 female and 9 male participants) 18–30 years of age were included in this study. Each participant underwent the saccadometry test twice, 1 week apart, by the same experienced clinician. To determine test–retest reliability, paired t tests and Wilcoxon signed-rank test were conducted to compare the means of two measures, and intraclass correlation coefficients were used to reflect the degree of correlation between measures.Results: Statistically significant differences were not observed when the first test–retest measures of latency, velocity, accuracy, and directional error rate were compared (p > 0.05). For prosaccades, intraclass correlation coefficient values of test–retest reliability between the first test and retest means were 0.707 for latency, 0.488 for velocity, 0.594 for accuracy, and −0.248 for directional error. For antisaccades, these values were 0.813 for latency, 0.48 for accuracy, 0.808 for velocity, and 0.807 for directional error.Conclusion: Saccadometry provides acceptable levels of test–retest reliability for both antisaccades and prosaccades. Test–retest reliability varied from poor to good for latency, velocity, accuracy, and directional error.

Background: Literature about the audio-vestibular function of children with pediatric-onset multiple sclerosis (POMS) is limited.Purpose: To characterize the peripheral and central audiological and vestibular findings of POMS and describe vestibular rehabilitation therapy as part of POMS management.Research Design: Retrospective case series.Study Sample: Three patients with POMS. Data Collection and Analysis: Retrospective chart review of comprehensive audio-vestibular battery data.Results: Both peripheral and central vestibular dysfunctions of varying degrees and stages of compensation were found.Conclusion: An audiogram and standard videonystagmography test may not capture the depth of audio-vestibular dysfunction in the POMS population. Comprehensive vestibular and hearing evaluations can support the interpretation of peripheral findings that may be influenced by central disorders. This testing should be considered to guide treatment for patients with POMS who present with relevant clinical screening assessment findings.

Background: Recent advancements in automated natural language processing (NLP) methods and tools have enhanced the efficacy and accuracy of quantitative analysis of natural language data. NLP offers significant potential for audiology by providing valuable insights from open-text responses about users' lived hearing aid experiences.Purpose: This study aimed to establish linguistic categories pertinent to the experiences of adults using hearing aids, with the ultimate goal of developing a specialized text processing module to facilitate natural language analysis of textual data on hearing aid experiences.Research Design: A modified electronic Delphi (e-Delphi) design was employed.Study Sample: A panel of 16 audiology experts from seven countries.Data Collection and Analysis: Two survey rounds were conducted. In round 1, experts rated categories from the Linguistic Inquiry and Word Count (LIWC) software and categories from principal component analysis of open-ended text data on hearing aid experiences. Experts also responded to open-ended prompts regarding categories derived from qualitative studies on hearing aid experiences. Responses were condensed and refined into items for rating during round 2. In round 2, experts reconsidered their ratings in light of the group answers of round 1. All ratings used a four-point Likert scale of importance. Measures of central tendency, levels of dispersion, and Cronbach's α reliability coefficients were conducted in both rounds for comparative purposes.Results: The open-ended section generated 26 items. Consensus was met on 53 linguistic categories encompassing social (e.g., social situations, social support), emotional (e.g., positive tone, negative tone), cognitive (e.g., cognitive processes, causation), lifestyle (e.g., work, leisure), hearing aid-related (e.g., sound quality, use and handling), and service delivery-related dimensions.Conclusions: The linguistic categories identified provide a foundation for developing a customized LIWC text processing module tailored to the analysis of hearing aid experiences. Future research is needed to refine and validate the custom text processing module.Clinical Relevance Statement: The findings provide a framework to enable the development of a customized hearing aid LIWC dictionary. Such a tool may enhance clinicians' ability to explore hearing aid outcomes and improve patient-centered care by integrating real-world experiences into clinical practice.

Background: Although approximately 80 percent of hearing loss cases are treatable with hearing aids (HAs), only one in four individuals who may benefit from them pursue them. Along with audiologists, physicians are integral parts of the hearing-health care team. Whether patients with hearing loss are more likely to pursue HA use based on the physician recommendation is unknown. Purpose: To investigate motivating factors and perceptions of prospective HA users, particularly the role of physician recommendations. Research Design: Patients 18 years and older who underwent an HA evaluation at our practice between January 2018 and December 2022 were identified. Patients were given a 17-question survey to assess their demographic characteristics and factors related to HA adoption via e-mail (n = 2,677) or as a physical copy (n = 487). Study Sample: Our sample (n = 321) included 182 female patients (57 percent) and 139 male patients (43 percent). Most patients identified as White/Caucasian (86 percent), followed by Black/African American (7 percent) and Hispanic/Latino (2 percent). Most patients were older adults (age 60 years and older), and 144 (45 percent) were older than 75 years. Intervention: We assessed the demographics and motivating factors related to HA adoption based on the results of the 17-question survey. Data Collection and Analysis: Data were analyzed using descriptive statistics, chi-square analyses, and multiple logistic regression. An α of 0.05 was set as the threshold of statistical significance. Results: Approximately 80 percent of participants adopted HAs after their evaluation. The most commonly selected factors that influenced their decision were cost, insurance coverage, and physician recommendation. Chi-square analyses were performed to compare these factors between patients who did and those who did not adopt HAs and yielded a significant difference (X² = 177.8; p < 0.0001). Patients' knowledge of multiple institutional locations that offer HAs (95 percent confidence interval [CI], 0.23-0.98; p = 0.045) and the office where they were evaluated (95 percent CI, 0.12-0.85; p = 0.019) were significant predictors of HA adoption. Conclusions: Our findings align with those of previous studies of motivating factors for HA adoption; however, with the addition of physician recommendation, our study showed higher HA adoption rates. These findings provide audiologists and physicians with insights regarding factors that impact HA adoption, which can help them develop a more individualized care plan during the initial evaluation.
背景:虽然大约80%的听力损失病例可以用助听器(HAs)治疗,但只有四分之一的人可能会从中受益。和听力学家一样,医生也是听力健康护理团队的组成部分。听力损失患者是否更有可能根据医生的建议使用HA尚不清楚。目的:调查激励因素和预期的医管局用户的看法,特别是医生推荐的作用。研究设计:确定2018年1月至2022年12月期间在我们诊所接受HA评估的18岁及以上患者。通过电子邮件(n = 2677)或实物副本(n = 487)对患者进行17个问题的调查,以评估他们的人口统计学特征和与采用HA相关的因素。研究样本:我们的样本(n = 321)包括182例女性(57%)和139例男性(43%)。大多数患者确定为白人/高加索人(86%),其次是黑人/非裔美国人(7%)和西班牙裔/拉丁裔(2%)。大多数患者是老年人(60岁及以上),144例(45%)年龄超过75岁。干预措施:根据17个问题的调查结果,我们评估了与采用医管局相关的人口统计数据和激励因素。数据收集与分析:采用描述性统计、卡方分析和多元逻辑回归对数据进行分析。以α 0.05为差异有统计学意义的阈值。结果:大约80%的参与者在评估后采用了HAs。影响他们决定的最常见因素是费用、保险范围和医生建议。采用卡方分析比较采用和未采用ha的患者的这些因素,结果显示差异有统计学意义(X²= 177.8;p < 0.0001)。患者对提供HA的多个机构地点的了解(95%置信区间[CI], 0.23-0.98; p = 0.045)和对他们进行评估的办公室(95% CI, 0.12-0.85; p = 0.019)是采用HA的重要预测因素。结论:我们的发现与之前关于HA采用的激励因素的研究一致;然而,加上医生推荐,我们的研究显示了更高的HA采用率。这些发现为听力学家和医生提供了有关影响HA采用的因素的见解,这可以帮助他们在初步评估期间制定更个性化的护理计划。

Background: Hyperacusis is an auditory perception disorder causing decreased sound tolerance to everyday sounds. Children with autism often exhibit symptoms of hyperacusis. This comorbidity can significantly impact the adaptability and social development of the children. Purpose: This study's objectives were to translate and psychometrically evaluate the Persian Pediatric Hyperacusis Questionnaire (P-HQ-P) and the prevalence determination of hyperacusis among children with or without autism. Study Sample: The study was conducted by assigning 60 parents of children diagnosed with level 1 autism spectrum disorder (ASD) and 30 parents of typical children to the ASD group and control group, respectively. Data Collection and Analysis: In the first stage, the Pediatric Hyperacusis Questionnaire (P-HQ) was translated into Persian, and in the second stage, its reliability and validity were assessed by the classical test theory methods. The P-HQ-P results were compared with the Persian Sensory Profile 2 (SP2-P). Results: The P-HQ-P demonstrated acceptable validity and reliability, with content validity ratio > 0.99, content validity index > 0.92, face validity > 0.90, cross-cultural validity > 0.94, α = 0.8, and intraclass correlation coefficient = 0.85. Spearman's rank correlation coefficient showed a strong correlation (r = 0.83) between the P-HQ-P score and a group of seven items from SP2-P. There was not a statistically significant difference in hyperacusis between genders. Conclusions: The psychometric properties of the P-HQ-P were found to be acceptable, which made it suitable for clinical and research usage. The prevalence of hyperacusis was reported at 27.8 percent of the total sample and 38.3 percent in the ASD group. Our findings suggest the need for further research on hyperacusis in the Iranian pediatric population.
