PURPOSE
To assess the hearing abilities of temporal ordering, temporal resolution and sound localization before and after the fitting of a hearing aid (HA) in individuals with unilateral hearing loss (UHL).
METHODS
There were evaluated 22 subjects, aged 18 to 60 years, diagnosed with sensorineural or mixed UHL, from mild to severe degrees. The study was divided into two stages: the pre and post-adaptation of HA. In both phases, subjects performed an interview, application of Questionnaire for Disabilities Associated with Impaired Auditory Localization, auditory processing screening protocol (APSP) and Random Gap Detection Test (RGDT).
RESULTS
This study found no statistically significant difference in sound localization and memory evaluations for verbal sounds in sequence, in RGDT and Questionnaire for Disabilities Associated with Impaired Auditory Localization.
CONCLUSION
With the effective use of hearing aids, individuals with UHL showed improvement in the auditory abilities of sound localization, ordering and temporal resolution.
目的
评估单侧听力损失（UHL）患者佩戴助听器（HA）前后的时间排序、时间分辨率和声音定位听力能力。
方法
评估了22名年龄在18至60岁之间、被诊断为感音神经性或混合性UHL（轻度至重度）的受试者。该研究分为两个阶段：HA适应前和适应后。在两个阶段中，受试者都进行了访谈、应用与听觉定位障碍相关的残疾问卷、听觉处理筛查方案（APSP）和随机间隙检测测试（RGDT）。
结果
本研究发现在RGDT和与听觉定位障碍相关的残疾问卷中，声音定位和言语声音序列记忆评估没有统计学上的显著差异。
结论
通过有效使用助听器，UHL患者在声音定位、排序和时间分辨率的听觉能力方面有所改善。
