The purpose of this project was to develop a spoken word-recognition task that could be used clinically to evaluate recognition performance of individuals with hearing loss in a background noise. The test instrument incorporated monosyllabic words at seven levels over a 35-dB range presented in a background of "multi-talker" babble that was fixed in level. In Experiment 1, we established normative data on 24 young adult listeners with normal hearing and on 50 older adult listeners with high-frequency hearing loss. In Experiment 2, we examined the effects that age and hearing loss have on understanding speech in multi-talker babble by studying 15 subjects in each decade interval from 20 to 79 years.
本项目的目的是开发一种口语单词识别任务，该任务可在临床上用于评估听力损失患者在背景噪声中的识别表现。测试仪器包含在35分贝范围内七个水平的单音节词，这些词呈现于固定水平的“多说话者”嘈杂背景中。在实验1中，我们建立了24名听力正常的年轻成年听众和50名高频听力损失的老年成年听众的规范数据。在实验2中，我们通过研究20至79岁每个十年间隔中的15名受试者，考察了年龄和听力损失对在多说话者嘈杂环境中理解言语的影响。
