Objectives. 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). Design. 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. Results. Pure tone audiometry results showed that the average hearing threshold of good ears and bad ears was HL and HL, respectively. The average hearing threshold of bad ears after wearing hearing aids was 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 percentage points and at 65 dB SPL by 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 (S_SSDN_AH), the speech recognition score (SRS) significantly increased by and 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 (S₀N_SSD), the SRS scores were reduced by and 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 (S₀N₀), the SRS was not significantly increased by percentage points at SNR equal to -2 dB compared to before wearing hearing aids. However, the SRS was significantly increased by percentage points at SNR equal to -5 dB compared to before wearing hearing aids. The average total GBI score was for the nine patients, with an average score of , , and 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. Conclusions. 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.

SoundBite 骨传导助听器对单侧耳聋患者语音识别和生活质量的影响。

目标。通过评估SoundBite骨传导助听器对单侧耳聋（SSD）患者语音识别能力的提高和效益量表问卷评分，分析其临床应用。设计。9 名 24 至 61 岁患有 SSD 超过 3 个月的患者参加了这项研究。患者能听懂并复述普通话，依从性好。在佩戴助听器一个月之前和之后，使用纯音测听阈值、安静和噪音中的语音识别以及格拉斯哥福利清单 (GBI) 福利量表评分对测量结果进行评估。结果。纯音测听结果显示，好耳朵和坏耳朵的平均听阈为 HL 和 HL 分别。戴助听器后坏耳的平均听阈为HL。统计分析表明，佩戴助听器后，坏耳的听力改善是显着的。语音测听结果表明，安静时坏耳朵的双音节单词识别分数在50 dB SPL时显着增加 百分比和在 65 dB SPL 时 百分点。对于噪声中的语音识别，当信号声音来自坏耳侧和噪声来自好耳侧（S _SSD N _AH）时，语音识别得分（SRS）显着提高了 和 佩戴助听器后，信噪比 (SNR) 分别为 -2 dB 和 -5 dB。当信号声来自患者正面，而噪声来自坏耳侧（S ₀ N _SSD）时，SRS 评分降低了 和 信噪比分别为-2分贝和-5分贝，与佩戴助听器前明显不同。当信号和噪声都来自患者的正面（S ₀ N ₀）时，SRS 没有显着增加与佩戴助听器之前相比，SNR 等于 -2 dB 时的百分比。然而，SRS显着增加了与佩戴助听器之前相比，SNR 等于 -5 dB 时的百分比。GBI 的平均总分是 对于 9 名患者，平均得分为 , ，和分别用于一般情况、社会支持和身体健康。问卷调查结果显示，佩戴 SoundBite 骨传导助听器后患者的生活质量有所提高。结论。SoundBite骨传导助听器是SSD患者的不错选择，它可以提高患者在安静和嘈杂环境中的语音识别能力，提高佩戴助听器后的生活质量。
