Speech understanding disorders in the elderly may be due to peripheral or central auditory dysfunctions. Asymmetry of results in dichotic testing increases with age, and may reflect on a lack of inter-hemisphere transmission and cognitive decline. To investigate auditory processing of aged people with no hearing complaints. clinical prospective. Twenty-two voluntary individuals, aged between 55 and 75 years, were evaluated. They reported no hearing complaints and had maximal auditory thresholds of 40 dB HL until 4 KHz, 80% of minimal speech recognition scores and peripheral symmetry between the ears. We used two kinds of tests: speech in noise and dichotic alternated dissyllables (SSW). Results were compared between males and females, right and left ears and between age groups. There were no significant differences between genders, in both tests. Their Left ears showed worse results, in the competitive condition of SSW. Individuals aged 65 or older had poorer performances than those aged 55 to 64. Central auditory tests showed worse performance with aging. The employment of a dichotic test in the auditory evaluation setting in the elderly may help in the early identification of degenerative processes, which are common among these patients.
老年人的言语理解障碍可能归因于外周或中枢听觉功能障碍。双耳分听测试结果的不对称性随年龄增长而增加，这可能反映了半球间传导的缺乏和认知能力的下降。为了研究无听力主诉的老年人的听觉处理情况，我们进行了一项临床前瞻性研究。对22名年龄在55至75岁之间的志愿者进行了评估。他们均无听力主诉，在4千赫兹以下的最大听觉阈值为40分贝听力级，最小言语识别分数的80%，且双耳外周对称。我们使用了两种测试：噪声中的言语测试和双耳交替双音节词测试（SSW）。对男性和女性、左耳和右耳以及不同年龄组之间的结果进行了比较。在这两种测试中，性别之间均无显著差异。在SSW的竞争条件下，他们的左耳表现较差。65岁及以上的个体比55至64岁的个体表现更差。中枢听觉测试显示，随着年龄增长，表现会变差。在老年人的听觉评估中使用双耳分听测试可能有助于早期识别这些患者中常见的退行性过程。
