To analyze the clinical application of SoundBite bone conduction hearing aids by assessing the improvement of speech recognition and the scores of the benefit scale questionnaire for patients with single-sided deafness (SSD).
Nine patients aged 24 to 61 years with SSD for more than 3 months were enrolled in this study. The patients could understand and repeat Mandarin and have good compliance with the study. The measurements were evaluated before and after one month of wearing hearing aids using the pure tone audiometry threshold, speech recognition in quiet and in noise, and the Glasgow Benefit Inventory (GBI) benefit scale score.
Pure tone audiometry results showed that the average hearing threshold of good ears and bad ears was 11.4 ± 2.6 dB HL and 89.9 ± 6.4 dB HL, respectively. The average hearing threshold of bad ears after wearing hearing aids was 23.5 ± 9.0 dB HL. Statistical analysis showed that the hearing improvement for the bad ears after wearing hearing aids was significant. The speech audiometry results showed that the disyllable word recognition score of the bad ears in quiet increased significantly at 50 dB SPL by 40 ± 12 percentage points and at 65 dB SPL by 71 ± 15 percentage points. As for the speech recognition in noise, when the signal sound came from the bad ear side and the noise from the good ear side (SN), the speech recognition score (SRS) significantly increased by 17 ± 6 and 9 ± 4 at a signal-to-noise ratio (SNR) of -2 dB and -5 dB, respectively, after wearing the hearing aids. When the signal sound came from the front of the patient and the noise from the bad ear side (SN), the SRS scores were reduced by 5 ± 5 and 7 ± 5 percentage points at SNR equal to -2 dB and -5 dB, which was significantly different from that before wearing the hearing aids. When the signal and noise both came from the front of the patients (SN), the SRS was not significantly increased by 5 ± 4 percentage points at SNR equal to -2 dB compared to before wearing hearing aids. However, the SRS was significantly increased by 5 ± 2 percentage points at SNR equal to -5 dB compared to before wearing hearing aids. The average total GBI score was 31 ± 12 for the nine patients, with an average score of 32 ± 10, 31 ± 8, and 30 ± 7 for general conditions, social support, and physical health, respectively. The results of the questionnaires showed that patients' quality of life was improved after wearing SoundBite bone conduction hearing aids.
SoundBite bone conduction hearing aids are a good choice for patients with SSD, as it could improve the speech recognition ability of patients both in a quiet and noisy environment and improves the quality of life after wearing hearing aids.
通过评估单侧聋（SSD）患者言语识别率的改善和受益量表问卷的评分，分析 SoundBite 骨导助听器的临床应用。
本研究纳入了 9 名年龄在 24 至 61 岁、SSD 时间超过 3 个月、能理解并重复普通话、且对研究有良好依从性的 SSD 患者。使用纯音听阈、安静和噪声环境下的言语识别以及格拉斯哥受益量表（GBI）评分，在佩戴助听器一个月前后分别对患者进行评估。
纯音听阈结果显示，健耳和患耳的平均听力阈值分别为 11.4±2.6dB HL 和 89.9±6.4dB HL。佩戴助听器后，患耳的平均听力阈值为 23.5±9.0dB HL。统计分析表明，佩戴助听器后患耳听力有显著改善。言语测听结果显示，在 50dB SPL 时，患耳的双音节词识别率在安静环境下显著提高了 40±12 个百分点，在 65dB SPL 时提高了 71±15 个百分点。对于噪声环境下的言语识别，当信号声来自患耳侧，噪声来自健耳侧（SN）时，佩戴助听器后，在 SNR 为-2dB 和-5dB 时，言语识别得分（SRS）分别显著提高了 17±6 和 9±4；当信号声来自患者前方，噪声来自患耳侧（SN）时，SRS 评分分别降低了 5±5 和 7±5 个百分点，与佩戴助听器前相比差异有统计学意义。当信号和噪声均来自患者前方时（SN），与佩戴助听器前相比，在 SNR 等于-2dB 时，SRS 仅增加了 5±4 个百分点，差异无统计学意义。然而，在 SNR 等于-5dB 时，SRS 显著增加了 5±2 个百分点。9 名患者的平均总 GBI 评分为 31±12，其中一般状况、社会支持和身体健康的平均评分分别为 32±10、31±8 和 30±7。问卷结果表明，患者佩戴 SoundBite 骨导助听器后生活质量得到提高。
SoundBite 骨导助听器是 SSD 患者的一个较好选择，因为它可以提高患者在安静和嘈杂环境中的言语识别能力，并改善佩戴助听器后的生活质量。
