参差扬扬格词试验(staggered spondaic word test,SSW test)是检查中枢听功能最常用的方法。检查时用40对扬扬格词,使一侧耳听到的第二个音节和另一侧耳听到的第一个音节重叠;形成以下4种情况:右侧无竞争者,右侧竞争,左侧竞争,及左侧无竞争者。本文对41例60～79岁的老人进行检查。他们的纯音平均听阈、语言接受阈都在正常范围内。与较年青的人对比,老人的SSW反应准确度低,变化性大。作者同意Brunt的看法:虽然SSW对中枢听神经系统的改变有诊断价值,但不能鉴别老年性中枢听神经
The staggered spondaic word test (SSW test) is the most commonly used method of checking the central hearing function. The check was made with 40 pairs of Youngsian words so that the second syllable heard by one ear overlaps with the first syllable heard by the other ear; the following four conditions result: no competitor on the right, competing on the right, left Competition, and no competitor on the left. This article examines 41 elderly people aged 60 to 79 years. Their pure tone average hearing threshold, language acceptance threshold are in the normal range. Compared with the younger people, the SSW response of the elderly is low in accuracy and changeable. The authors agree with Brunt that although SSW is diagnostic of changes in the central auditory nervous system, it is not possible to identify senile central auditory nerve
