感觉神经性听力损失在听力受损老年人的言语识别困难中所起的作用进行了研究。解决这个问题的一种方法是对三组受试者的表现进行组间比较：(A)听力正常的年轻人；(B)听力受损的老年人；以及(C)听力正常的年轻人，他们的感觉神经性听力损失与由频谱形状的掩蔽噪声造成的老年受试者的听力损失相当。研究这一问题的另一种方法是使用相关分析来检验老年听力受损受试者群体中听觉和语音识别之间的关系。另一种方法是使用包含阈值升高调整的声学指数来检查听觉在听力受损老年人的言语识别能力中所起的作用。在这个实验中，我们选择了广泛的听力条件。结论是，老年听障受试者言语识别能力的主要决定因素是他们的阈值升高。
The role that sensorineural hearing loss plays in the speech-recognition difficulties of the hearing-impaired elderly is examined. One approach to this issue was to make between-group comparisons of performance for three groups of subjects: (a) young normal-hearing adults; (b) elderly hearing-impaired adults; and (c) young normal-hearing adults with simulated sensorineural hearing loss equivalent to that of the elderly subjects produced by a spectrally shaped masking noise. Another approach to this issue employed correlational analyses to examine the relation between audibility and speech recognition within the group of elderly hearing-impaired subjects. An addition approach was pursued in which an acoustical index incorporating adjustments for threshold elevation was used to examine the role audibility played in the speech-recognition performance of the hearing-impaired elderly. A wide range of listening conditions was sampled in this experiment. The conclusion was that the primary determiner of speech-recognition performance in the elderly hearing-impaired subjects was their threshold elevation.
