摘要

目的

探究人工耳蜗蓝牙直连（bluetooth direct streaming， BDS）技术在临床听阈及言语识别测试中的应用价值，比较其与传统声场（sound field，SF）测听条件下言语识别的差异，评估其作为人工耳蜗术后听觉功能评估补充手段的可行性，为人工耳蜗远程调试、居家随访及康复效果监测提供参考。

方法

纳入31例诺尔康人工耳蜗植入者作为研究对象，采用平衡交叉设计控制测试顺序效应。受试者分别在BDS与SF条件下完成测试，通过主观响度匹配使2种条件下输出强度保持一致。采用中文开放式言语感知评估材料，在安静环境下测试双音节词及短句识别率。应用配对

检验比较两种测试条件下言语识别率的差异，计算BDS相较于SF条件的识别改善幅度，统计个体表现出BDS优势的受试者比例。

结果

31例受试者在BDS条件下言语识别率显著高于SF条件（

＜0.05），其中BDS

条件下双音节词识别率为69.6%±24.0%，SF条件下为62.9%±25.1%，20例（64.5%）受试者表现出BDS优势；BDS条件下短句识别率为65.7%±31.3%，SF条件下为55.1%±27.6%，26例（83.9%）受试者表现出BDS优势。BDS对短句识别的提升幅度为10.6%±16.1%，高于双音节词的6.7%±15.2%，但二者改善幅度无显著差异（

＝0.203）。

结论

人工耳蜗BDS技术可在安静环境下提高植入者言语识别表现，尤其在短句识别测试中显示出明显优势。该技术操作便捷，可减少测试环境噪声、混响及声场设备条件对结果的影响，有望作为传统SF测听的有效补充。本研究为BDS技术应用于人工耳蜗术后评估、远程调试及患者自测提供了初步数据支持，对优化术后康复评估流程、提升随访效率具有一定临床应用价值。

Abstract

Objective

To investigate the clinical value of Bluetooth Direct Streaming (BDS) technology in hearing threshold and speech recognition testing for cochlear implant users

to compare speech recognition outcomes between BDS and conventional sound-field (SF) testing conditions

and to evaluate the feasibility of BDS as a supplementary approach to postoperative auditory assessment. This study aimed to provide evidence for remote programming

home-based follow-up

and rehabilitation monitoring in cochlear implant users.

Methods

Thirty-one Nurotron cochlear implant recipients were enrolled. A balanced crossover design was applied to control for potential order effects. Each participant completed speech recognition testing under both BDS and SF conditions. Subjective loudness matching was performed to make the output levels under the two conditions as comparable as possible. Chinese open-set speech perception materials were used to assess disyllabic word and sentence recognition in quiet. Paired t-tests were used to compare speech recognition scores between the two testing conditions. The improvement in recognition scores under BDS relative to SF was calculated

and the proportion of participants showing a BDS advantage at the individual level was also analyzed.

Results

Overall

speech recognition scores under BDS were significantly higher than those under SF (

0.05). The disyllabic word recognition score was 69.6%±24.0% under BDS and 62.

9%±25.1% under SF

with 20 participants (64.5%) showing a BDS advantage. The sentence recognition score was 65.7%±31.3% under BDS and 55.1%±27.6% under SF

with 26 participants (83.9%) showing a BDS advantage. The improvement in sentence recognition under BDS was 10.6%±16.1%

greater than the improvement in disyllabic word recognition (6.7%±15.2%); however

the difference between the two improvement magnitudes was not statistically significant (

＝0.203).

Conclusion

The BDS technology can improve speech recognition performance in cochlear implant users in quiet

particularly in sentence recognition testing. This technique is easy to operate and may reduce the interference from environmental noise

reverberation

and sound-field equipment conditions on test results. Therefore

the BDS has the potential to serve as an effective supplement to conventional SF testing. The present study provides preliminary evidence supporting the application of BDS to postoperative assessment

remote programming

and patient self-testing for cochlear implant users

and may contribute to optimizing postoperative rehabilitation assessment and improving follow-up efficiency.
