Hearing loss limits communication and social activity, and hearing aids (HAs) are an efficient rehabilitative option for improving oral communication and speech comprehension, as well as the psychosocial comfort of people with hearing loss. To overcome this problem, over-the-counter amplification devices including personal sound amplification products and wearable augmented reality devices (WARDs) have been introduced.
This study aimed to evaluate the clinical effectiveness of WARDs for patients with mild to moderate hearing loss.
A total of 40 patients (18 men and 22 women) with mild to moderate hearing loss were enrolled prospectively in this study. All participants were instructed to wear a WARD, Galaxy Buds Pro (Samsung Electronics), at least 4 hours a day for 2 weeks, for amplifying ambient sounds. Questionnaires including the Korean version of the abbreviated profile of hearing aid benefit (K-APHAB) and the Korean adaptation of the international outcome inventory for hearing aids (K-IOI-HA) were used to assess personal satisfaction in all participants. Audiologic tests, including sound field audiometry, sound field word recognition score (WRS), and the Korean version of hearing in noise test (K-HINT), were administered to 14 of 40 patients. The tests were performed under two conditions: unaided and aided with WARDs.
The mean age of the participants was 55.4 (SD 10.7) years. After 2 weeks of the field trial, participants demonstrated a benefit of WARDs on the K-APHAB. Scores of 3 subscales of ease of communication, reverberation, and background noise were improved significantly (P<.001). However, scores regarding aversiveness were worse under the aided condition (P<.001). K-IOI-HA findings indicated high user satisfaction after the 2-week field trial. On audiologic evaluation, the K-HINT did not show significant differences between unaided and aided conditions (P=.97). However, the hearing threshold on sound field audiometry (P=.001) and the WRS (P=.002) showed significant improvements under the aided condition.
WARDs can be beneficial for patients with mild to moderate hearing loss as a cost-effective alternative to conventional hearing aids.
听力损失限制了交流和社交活动，助听器（HA）是改善语言交流和言语理解能力以及听力损失患者心理社会舒适度的有效康复选择。为了解决这个问题，已经引入了包括个人声音增强产品和可穿戴增强现实设备（WARD）在内的非处方放大设备。
本研究旨在评估 WARD 对轻度至中度听力损失患者的临床效果。
本前瞻性研究共纳入 40 名（18 名男性和 22 名女性）轻度至中度听力损失患者。所有参与者均被指示每天佩戴 WARD（三星电子 Galaxy Buds Pro）至少 4 小时，以放大环境声音，为期 2 周。所有参与者均使用韩国版简化助听器受益量表（K-APHAB）和韩国版国际助听器效果问卷（K-IOI-HA）问卷评估个人满意度。对 40 名患者中的 14 名进行了听力学测试，包括声场测听、声场言语识别得分（WRS）和韩国噪声下听力测试（K-HINT）。这些测试在两种条件下进行：未佩戴和佩戴 WARD。
参与者的平均年龄为 55.4（SD 10.7）岁。经过 2 周的现场试验，参与者在 K-APHAB 上表现出 WARD 的益处。在沟通方便、混响和背景噪声 3 个亚量表的评分上有显著改善（P<.001）。然而，在辅助条件下，关于令人不快的评分更差（P<.001）。K-IOI-HA 调查结果表明，经过 2 周的现场试验，用户满意度很高。在听力学评估中，K-HINT 在未佩戴和佩戴条件下没有显著差异（P=.97）。然而，声场测听的听力阈值（P=.001）和 WRS（P=.002）在辅助条件下有显著改善。
WARD 可作为传统助听器的经济有效替代方案，为轻度至中度听力损失患者带来益处。
