中文摘要

目的： 本研究旨在评估2 kHz以上感音神经性听力损失个体的时间分辨率、噪声中言语理解及日常交流困难。
方法： 纳入30名年龄38-59岁的高频感音神经性听力损失（HF-SNHL）成人为研究组，30名年龄37-59岁听力正常者为对照组。参与者完成了间隙检测、随机间隙检测、土耳其矩阵测试（TMT）以及言语、空间感知和听力质量（SSQ）量表。进行了统计比较和决策树分析。
结果： 在时间分辨率测试、言语识别阈（SRT）、TMT在-5 dB信噪比条件下的言语可懂度百分比以及SSQ结果方面，组间观察到显著差异。决策树分析表明，SSQ的言语感知子量表和噪声程序中的TMT SRT被认为有助于识别HF-SNHL。
结论： 发现HF-SNHL个体的时间分辨率降低，噪声中言语理解受损。SSQ在识别HF-SNHL个体中发挥了决定性作用。

英文摘要

OBJECTIVE: This study aimed to evaluate temporal resolution, speech understanding in noise, and daily communication difficulties in individuals with sensorineural hearing loss above 2 kHz.
METHOD: Thirty adults aged 38-59 years with high-frequency sensorineural hearing loss (HF-SNHL) were included as the study group, and 30 individuals aged 37-59 years with normal hearing as the control group. Participants completed the Gap Detection, Random Gap Detection, Turkish Matrix Test (TMT), and the Speech, Spatial Perception, and Hearing Quality (SSQ) scale. Statistical comparisons and decision-tree analyses were conducted.
RESULTS: Significant differences between groups were observed in temporal resolution tests, speech recognition thresholds (SRT), and speech intelligibility percentages in -5 dB signal to noise ratio condition of the TMT, as well as in SSQ results. Decision-tree analysis indicated that the Speech Perception subscale of the SSQ and the TMT SRT in noise procedure were considered useful for identifying HF-SNHL.
CONCLUSIONS: Temporal resolution was found to be reduced, and speech comprehension in noise impaired in individuals with HF-SNHL. The SSQ played a decisive role in identifying individuals with HF-SNHL.
