Abstract

Purpose

The purpose of this study is to longitudinally investigate the effects of using CROS/BiCROS hearing aids on the listening effort and speech perception in noise skills of individuals with single-sided deafness (SSD).

Methods

Nineteen people with SSD who were going to use CROS/BiCROS hearing aids for the first time participated in the study. Participants were evaluated before they started using hearing aids and after 1 week, 3, and 6 months after they started using them. In every session, a dual-task paradigm was applied to measure listening effort, and the Turkish Matrix Test (TM) was applied to measure speech understanding performance in noise. The dual-task paradigm was evaluated at three different individual signal-to-noise ratios (SNR) determined according to the subjects' TM performance. Repeated measures ANOVA tests were used to evaluate whether the participants' dual-task paradigm and TM performances differed according to sessions.

Results

A significant difference was observed between both the dual-task paradigm and TM scores according to measurement time (p < 0.001). In pairwise comparisons with Bonferroni corrections, it was observed that there was a significant difference between all periods (p < 0.001). While the dual-task paradigm reaction times obtained in all three difficult listening conditions were highest before using the device, they were lowest at the sixth-month evaluation.

Conclusion

This is the first study to longitudinally examine how CROS/BiCROS hearing aid use affects both speech-in-noise ability and listening effort. As a result of this study, it was seen that the use of CROS/BiCROS increased speech understanding performance in noise and reduced listening effort after starting to use them. Furthermore, as the use of the device continued, it was observed that speech performance in noise increased and listening effort decreased over time.

单侧耳聋CROS和BiCROS助听器使用者在噪声环境下听力和言语感知的纵向评价

目的本研究的目的是纵向探讨使用CROS/BiCROS助听器对单侧耳聋（SSD）患者的听力努力和噪音技能中的言语感知的影响。方法对19例首次使用CROS/BiCROS助听器的SSD患者进行研究。参与者在开始使用助听器前、开始使用助听器1周、3周和6个月后进行评估。在每个会话中，采用双任务范式测量听力努力，并采用土耳其矩阵测试（TM）测量噪声下的语音理解表现。双任务范式以三种不同的个体信噪比（SNR）进行评估，信噪比是根据被试的TM表现确定的。使用重复测量方差分析来评估参与者的双任务范式和TM表现是否因会话而不同。结果双任务范式与TM得分在测量时间上存在显著差异（p < 0.001）。在与Bonferroni校正的两两比较中，观察到所有时期之间存在显著差异（p < 0.001）。虽然在所有三种困难听力条件下获得的双任务范式反应时间在使用设备之前是最高的，但在第六个月的评估中是最低的。本研究首次对使用CROS/BiCROS助听器对噪声中言语能力和听力努力的影响进行了纵向研究。本研究的结果表明，使用CROS/BiCROS可以提高噪音环境下的语音理解能力，并减少开始使用后的听力努力。此外，随着设备的继续使用，观察到在噪音下的语音表现会随着时间的推移而提高，而听力努力会随着时间的推移而下降。
