Purpose: The purpose of this study was to investigate and analyze the use of the frequency modulation (FM) systems. The degree of speech perception in various school environment and participation in the class using the FM systems for hearing-impaired students and teachers who use the FM systems in integrated education.Methods: Questions were composed of multiple-choice statements that can check for duplicate answers and short-answer for questions developed as a mobile app and implemented by sending individual text messages. The subjects were elementary, middle, and high school eight students receiving integrated education and their eight teachers.Results: The overall opinion of using the FM systems was ‘very satisfied’ for all students, and 75% of teachers showed more satisfaction. FM systems were used in various environments, curriculum activity, experiential learning, practice, group activities, and audiovisual education through media such as TV or computer. The FM system was helpful at any distance in quiet, noisy, or reverberant environments. Using the FM system, the hearing-impaired student felt positive effects when listening to the conversation of the teacher or other friends, but felt negative effects when the teacher and other friends did not understand the speech of the hearing-impaired student.Conclusion: FM systems provided a better classroom acoustic environment for hearing-impaired students. Understanding classroom acoustics such as noise situation, signal-to-noise ratio, and reverberation time expects effective physical integration for the integrated education of hearing-impaired students.
目的:本研究的目的是调查和分析调频系统的使用情况。综合教育中使用调频系统的听力受损学生和教师在不同学校环境中的言语感知程度和课堂参与程度。方法:问题由多项选择题组成,可以检查重复答案和简答问题,开发为移动应用程序,通过发送个人短信实现。研究对象是接受融合教育的小学、初中和高中的8名学生和他们的8名教师。结果:所有学生对使用FM系统的总体评价为“非常满意”,75%的教师表示满意。调频系统被用于各种环境、课程活动、体验式学习、实践、小组活动以及通过电视或电脑等媒体进行的视听教育。调频系统在安静、嘈杂或混响的环境中对任何距离都有帮助。使用FM系统,听障学生在听老师或其他朋友的对话时感受到积极的影响,而当老师和其他朋友不理解听障学生的语言时感受到消极的影响。结论:调频系统为听障学生提供了较好的课堂声环境。了解课堂声学,如噪声情况、信噪比、混响时间等,有助于对听障学生进行有效的物理融合教育。

S. Oh, Junghwa Bahng
The importance of tele-audiology service delivery and accessibility has highlighted with the COVID-19 pandemic. Tele-audiology is an alternative method delivering various hearing intervention services including counselling, evaluation, fitting, and rehabilitation through telecommunication. The essential goal of tele-audiology service delivery is to obtain the best hearing rehabilitation outcomes equivalent to face-to-face service. Even though it has several advantages in aspects of service accessibility and effectiveness, convenience, and cost, still there are many challenges faced by audiologists, clients and administrators in order to implement tele-services in Korea. The present brief communication seeks to raise awareness in preparing and delivering the tele-audiology services with several considerations and challenges. We also focus on professional liability and training, service environment and information technology, and establishment of social system underling the tele-audiology service delivery in Korea.
随着COVID-19大流行,远程听力学服务提供和可及性的重要性得到了突出。远程听力学是一种通过电信提供各种听力干预服务的替代方法,包括咨询、评估、装配和康复。远程听力学服务提供的基本目标是获得相当于面对面服务的最佳听力康复结果。尽管它在服务可及性和有效性、便利性和成本方面具有若干优势,但在韩国实施远程服务仍然面临着听力学家、客户和管理人员的许多挑战。本简短的通讯旨在提高人们对准备和提供远程听力学服务的认识,其中包括若干考虑和挑战。我们还专注于专业责任和培训,服务环境和信息技术,以及建立韩国远程听力学服务提供的社会体系。

Purpose: Sound therapy is a useful rehabilitation approach that focuses on listening to external stimuli to reduce the perception of and negative reactions to tinnitus. In this study, we investigated whether the benefits of sound therapy for tinnitus were maintained after treatment completion.Methods: The study included 18 adults with chronic sensorineural tinnitus. The intervention used was sound therapy based on the mixing point level of each participant. Participants received sound therapy for 6 months; the Korean version of the Tinnitus Primary Function Questionnaire was administered before, after, and 6 months after completion of sound therapy to confirm any resolution of tinnitus.Results: The beneficial effects against tinnitus were maintained even 6 months post-therapy in 18 participants who showed significant improvement in mean questionnaire scores following sound therapy. With regard to the mean total score and mean subscale scores of emotion, sleep, concentration, and hearing, improvements between the baseline and 6-month follow-up were 24.22, 26.23, 25.22, 29.56, and 15.89, respectively.Conclusion: Sound therapy may be a potentially useful strategy that maintains improvement in tinnitus even after treatment. This fact may be useful to hearing professionals who may consider sound therapy for management of tinnitus.

Purpose: The aim of this study was to examine test-retest reliability and validity of the adaptive Korean matrix sentence-in-noise test for elderly group with normal hearing (ENH) and elderly group with hearing impairment (EHI).Methods: Twenty ENH listeners and 20 EHI listeners based on the World Health Organization (WHO)-proposed hearing-impairment grade participated. For the test-retest reliability of the Korean matrix sentence-in-noise test, each subject was assessed twice in a 2-week interval using three types of noise: speech-shaped noise, International Collegium of Rehabilitative Audiology noise, and International Speech Test Signal. The test-retest agreement was judged by the intraclass correlation coefficient (ICC) and Bland-Altman plots. To differentiate between real change and random measurement error, the standard error of measurement (SEM) and the minimal detectable change (MDC) were also obtained as another reliability index. For the concurrent validity, the results of the Matrix test were compared to the results of the Korean-version Hearing In Noise Test (K-HINT).Results: The test-retest reliability was good to excellent for ENH and EHI groups (ICC, 0.84~0.98). Both groups showed stable reliability, but the ENH group showed smaller SEM and MDC values than the EHI group. No systematic errors were found from the Bland-Altman plots. The correlation between the results of the Matrix test and the K-HINT test was high, revealing good concurrent validity.Conclusion: The Korean matrix sentence-in-noise test appeared to be valid and reliable for the elderly. The Korean matrix sentence-in-noise test can be utilized for clinical measurement of the speech-in-noise ability of elderly individuals.
目的:本研究旨在检验老年人听力正常组(ENH)和老年听力障碍组(EHI)自适应朝鲜语矩阵噪声测试的重测信度和效度。方法:选取20名按照世界卫生组织(WHO)听力障碍分级的ENH听者和EHI听者。对于韩语矩阵句子噪声测试的重测信度,每个被试在2周间隔内使用三种类型的噪声进行两次评估:语音形噪声、国际康复听力学学院噪声和国际语音测试信号。通过类内相关系数(ICC)和Bland-Altman图判断检验-重验一致性。为了区分真实变化和随机测量误差,还获得了测量标准误差(SEM)和最小可检测变化(MDC)作为另一个可靠性指标。对于并发效度,我们将矩阵测验的结果与韩国版噪音听力测验(K-HINT)的结果进行比较。结果:ENH组和EHI组的重测信度为良至优(ICC, 0.84~0.98)。两组均表现出稳定的信度,但ENH组的SEM和MDC值小于EHI组。Bland-Altman图没有发现系统误差。矩阵检验结果与K-HINT检验结果的相关性较高,显示出较好的并发效度。结论:朝鲜语矩阵噪声句子测验对老年人具有较好的有效性和可靠性。韩文矩阵句子噪声测试可用于临床测试老年人的语音噪声能力。

Purpose: The purpose of the current study was to investigate the perspectives of speech-language pathologists (SLPs) in South Korea about treating adolescents and adults with developmental disabilities.Methods: Survey results of 107 SLPs in South Korea were analyzed in the current study. Descriptive and inferential statistics were used in the analysis procedures.Results: Majority of the participants (92/107 participants) had treatment experience of adolescents and adults with developmental disabilities. However, such a treatment was mainly for middle- and high-school students with developmental disabilities. Furthermore the recognition of necessity of therapy, knowledge and confidence level were higher for middle- and high-school students than adults with developmental disabilities (p < 0.05). In addition, most participants acknowledged that the lack of financial support was a reason for adolescents and adults with developmental disabilities not to receive speech language treatment.Conclusion: The results of the current study emphasized that financial support would be needed to provide more appropriate speech language treatment for adults with developmental disabilities. In addition, there should be more re-education programs on developmental disabilities in order to help SLPs to provide more efficient treatment for adolescents and adults with developmental disabilities.
目的:本研究的目的是调查韩国语言病理学家在治疗青少年和成人发育障碍方面的观点。方法:对韩国107家slp的调查结果进行分析。在分析过程中使用了描述性和推断性统计。结果:绝大多数参与者(92/107)有青少年和成人发育障碍的治疗经历。然而,这种治疗主要针对有发育障碍的中学生和高中生。初高中学生对治疗必要性的认知程度、知识水平和信心水平均高于发育障碍成人(p < 0.05)。此外,大多数与会者承认,缺乏经济支持是青少年和成人发育障碍不接受言语语言治疗的一个原因。结论:目前的研究结果强调,需要财政支持,为成人发育障碍提供更合适的言语语言治疗。此外,应该有更多的关于发育障碍的再教育项目,以帮助特殊服务提供者为患有发育障碍的青少年和成年人提供更有效的治疗。

Sound Localization in Unilateral Cochlear Implant Users 单侧人工耳蜗使用者的声音定位
Q3 Medicine Pub Date : 2022-07-31 DOI: 10.21848/asr.220001
Sungmin Lee
Purpose: Sound is localized by two ears. People with bilaterally severe-to-profound hearing loss may struggle to identify the direction of a sound if their hearing device delivers sound only one ear due to the loss of binaural advantage. The purpose of this study was to systematically investigate the sound localization performance of people with unilateral cochlear implant users. Methods: Ten unilateral cochlear implant users and 10 normal hearing adults participated in this study. Sound localization tests were conducted using five stimuli (speech, speech with noise, 500 Hz warble tone, 1 kHz warble tone, and 4 kHz warble tone) presented from eight loud-speakers. Correct responses and root- mean-square errors were obtained to investigate the localization performances and error patterns. Additional factors including the Korean-Speech Spatial and Qualities of Hearing Questionnaire were also analyzed. Results: Localization performance was significantly poor in the unilateral cochlear implant group showing polar patterns toward their hearing side. While the normal hearing group showed better localization for speech in quiet conditions compared to 500 Hz warble tone, the cochlear implant group did not show any statistical difference in performance across the stimuli due to their very poor performance. The Korean-Speech Spatial and Qualities of Hearing Questionnaire was associated with localization performance in limited conditions. Conclusion: The present study revealed that unilateral cochlear implant users correctly localize a sound at nearly chance levels. The Korean-Speech Spatial and Qualities of Hearing Questionnaire predict localization performance for unilateral cochlear implant users only for particular conditions.
用途:声音由两耳定位。由于双耳优势的丧失,双耳重度或重度听力损失的人可能很难识别声音的方向,如果他们的助听器只能传递单耳声音。本研究的目的是系统地调查单侧人工耳蜗使用者的声音定位表现。方法:10例单侧人工耳蜗使用者和10例听力正常的成年人参与本研究。声音定位测试使用来自8个扬声器的5种刺激(语音、带噪声的语音、500 Hz颤音、1 kHz颤音和4 kHz颤音)进行。得到了正确的响应和均方根误差,研究了定位性能和误差模式。此外,还分析了韩国语语音空间和听力质量问卷等附加因素。结果:单侧人工耳蜗组定位表现明显较差,呈现向听力侧的极性模式。与500赫兹的颤音相比,听力正常的一组在安静的条件下表现出更好的语言定位,而人工耳蜗组由于表现非常差,在不同的刺激下没有表现出任何统计差异。韩国语空间和听力质量问卷在有限条件下与本地化表现相关。结论:本研究显示单侧人工耳蜗使用者对声音的定位几乎是随机的。韩国语空间和听力质量问卷仅在特定条件下预测单侧人工耳蜗使用者的定位表现。

Chang Kyu Kim, Junghwa Bahng
Purpose: This study investigates the knowledge of and attitudes toward hearing loss and hearing aids (HA) and cochlear implants (CI) based on background. Methods: A total of 356 adults, including users of HA and CI participated with a variety of background variables, including age, use of amplification, experience with hearing-impaired listeners, and educational majors in audiology and speech-language pathology. The group completed 10 questions on their knowledge of and attitudes toward hearing loss, HA and CI. Results: Almost all the participants understood HA and CI, but HA and CI users had a low level of knowledge of hearing loss, HA and CI. Participants had positive attitudes toward HA and CI. However, HA and CI current users were mystified by their hearing devices. They had no negative attitudes toward hearing devices that is worn by people with hearing loss, but non-users felt uncomfortable if others noticed they were using HA and CI. Students with audiology and speech-language pathology majors showed greater knowledge and more positive attitudes toward hearing loss and HA and CI. Conclusion: Despite most participants having a good knowledge of hearing loss, current device users had a rather low level of knowledge about hearing loss and their devices. These results indicate that users need more education about hearing loss and their own devices. Further, some non-users felt a stigma toward the use of HA and CI. These results suggest that more education is needed for better knowledge and more positive attitudes toward hearing loss and both HA and CI.
目的:调查听力损失、助听器(HA)和人工耳蜗(CI)的认知和态度。方法:共有356名成年人,包括HA和CI的使用者,参与了各种背景变量,包括年龄,扩音器的使用,听力受损听众的经验,听力学和语言病理学的教育专业。该小组完成了10个关于他们对听力损失、HA和CI的知识和态度的问题。结果:几乎所有参与者都了解HA和CI,但HA和CI使用者对听力损失、HA和CI的了解程度较低。参与者对HA和CI持积极态度。然而,HA和CI的当前用户对他们的助听器感到困惑。他们对听力损失的人佩戴的助听器没有负面态度,但如果其他人注意到他们在使用HA和CI,非用户会感到不舒服。听力学和语言病理学专业的学生对听力损失、HA和CI的认识和态度更积极。结论:尽管大多数参与者对听力损失有很好的了解,但现有设备使用者对听力损失及其设备的了解程度相当低。这些结果表明,用户需要更多关于听力损失和他们自己的设备的教育。此外,一些非用户对HA和CI的使用感到反感。这些结果表明,需要更多的教育,以更好地了解和更积极的态度对待听力损失和HA和CI。

Methods: A total of 356 adults, including users of HA and CI participated with a variety of background variables, including age, use of amplification, experience with hearing-impaired listeners, and educational majors in audiology and speech-language pathology. The group completed 10 questions on their knowledge of and attitudes toward hearing loss, HA and CI. Results: Almost all the participants understood HA and CI, but HA and CI users had a low level of knowledge of hearing loss, HA and CI. Participants had positive attitudes toward HA and CI. However, HA and CI current users were mystified by their hearing devices. They had no negative attitudes toward hearing devices that is worn by people with hearing loss, but non-users felt uncomfortable if others noticed they were using HA and CI. Students with audiology and speech-language pathology majors showed greater knowledge and more positive attitudes toward hearing loss and HA and CI. Conclusion: Despite most participants having a good knowledge of hearing loss, current device users had a rather low level of knowledge about hearing loss and their devices.

Q3 Medicine Pub Date : 2022-07-31 DOI: 10.21848/asr.220062
M. Park, Soonyoung Oh
Purpose: The purpose of this study is to investigate hearing aid satisfaction, quality of life, and tinnitus of elderly hearing aid users to help hearing aid rehabilitation of the elderly. Methods: A total of 50 elderly hearing aid users (average age 75.7 years) with or without tinnitus participated in this study. We implemented pure tone audiometry and tinnitogram and conducted four questionnaires including Satisfaction with Amplification in Daily Life (SADL), World Health Organization Quality of Life-BREF (WHOQOL-BREF), Visual Analogue Scale (VAS), and Tinnitus Handicap Inventory (THI).Results: Positive correlations were found between SADL and WHOQOL-BREF scores. The average total SADL scores and WHOQOL-BREF scores are 5 points and 3.4 points respectively. There were no significant differences in the average SADL and WHOQOL-BREF scores between the elderly with tinnitus and the elderly without tinnitus. About 90% of the elderly with tinnitus described high frequency tinnitus above 2,000 Hz. Eighty-eight percent of the respondents had an experience of tinnitus therapy and 67% of the elderly with tinnitus therapy experiences reported that tinnitus therapy was not helpful. Ninety-two percent of the respondents stated that wearing hearing aid was helpful to reduce their tinnitus. The emotional and catastrophic subscales of THI were correlated with VAS scores. Conclusion: Positive correlations were found between SADL and WHOQOL-BREF scores regardless of tinnitus presence. Tinnitus of elderly hearing users was not directly related to the quality of life and successful hearing aid intervention could be a key factor in improving the quality of life of the elderly.
目的:本研究旨在了解老年助听器使用者的助听器满意度、生活质量及耳鸣情况,为老年人助听器康复提供帮助。方法:50例老年助听器使用者,平均年龄75.7岁,伴有或不伴有耳鸣。我们采用纯音听力学和耳鸣图,并进行4项问卷调查,包括日常生活放大满意度(SADL)、世界卫生组织生活质量(WHOQOL-BREF)、视觉模拟量表(VAS)和耳鸣障碍量表(THI)。结果:SADL与WHOQOL-BREF评分呈正相关。平均SADL总分为5分,WHOQOL-BREF总分为3.4分。耳鸣老年人与非耳鸣老年人的平均SADL和WHOQOL-BREF评分差异无统计学意义。大约90%的老年耳鸣患者表现为2000赫兹以上的高频耳鸣。88%的受访者有耳鸣治疗经历,67%有耳鸣治疗经历的老年人耳鸣治疗无效。92%的受访者表示,佩戴助听器有助于减少耳鸣。THI的情绪和灾难分量表与VAS评分相关。结论:无论是否存在耳鸣,SADL与WHOQOL-BREF评分均呈正相关。老年听力使用者耳鸣与生活质量无直接关系,助听器干预的成功可能是提高老年人生活质量的关键因素。

Purpose: The purpose of this study is to identify relationships performances among subjective memory, objective memory, and naming of healthy elderly adults. Methods: A total of 77 healthy elderly adults aged 65 or older in South Korea participated in this study. Subjective Memory Complaints Questionnaire was used to evaluate the subjective memory loss of the elderly, and the Seoul Verbal Learning Test was used to evaluate objective memory. The Korean version of Boston Naming Test was used as a confrontation naming task and Controlled Oral Word Association Test was used as a generative naming task. Results: First, the subjective memory and objective memory of the healthy elderly adults showed a significant correlation, and the naming performances of the healthy elderly adults showed a significant correlation with the recall ability of the objective memory. In addition, it could be seen that the ‘supermarket’ category of the generative naming was a task that reflected both subjective and objective memory of the general elderly. Conclusion: The results of this study are meaningful in that they have identified the usefulness of subjective memory reporting at clinical sites and in that they have presented basic data on the subjective·objective memory and the naming performances of healthy elderly adults.
目的:探讨健康老年人主观记忆、客观记忆与命名之间的关系。方法:韩国共77名65岁及以上的健康老年人参与本研究。采用主观记忆抱怨问卷对老年人的主观记忆丧失进行评价,采用首尔语言学习测验对老年人的客观记忆进行评价。韩国版波士顿命名测试作为对抗命名任务,对照口语单词联想测试作为生成命名任务。结果:第一,健康老年人的主观记忆与客观记忆存在显著相关,健康老年人的命名表现与客观记忆的回忆能力存在显著相关。此外,可以看出生成命名的“超市”类别是一个反映一般老年人主观和客观记忆的任务。结论:本研究的结果具有重要意义,因为它确定了主观记忆报告在临床现场的有用性,并提供了健康老年人主客观记忆和命名表现的基本数据。
