The focus of this paper is on the effects of age on speech perception, with reference to pertinent psychoacoustic findings. The difficulties of older listeners are related to the well-known effects of high-frequency hearing loss on speech perception in quiet, and to temporal processing declines not predictable from the audiogram that account for reduced ability to listen in complex, noisy conditions. We also discuss issues of research interpretation; e.g. the need for researchers and clinicians to be alert to the frequent confound between degree of hearing loss and age. The implications of age-related changes in auditory speech processing for future practice and research are discussed relative to interactions between older individuals and their acoustic environments.
本文的重点是年龄对言语感知的影响，并参考了相关的心理声学研究结果。年长听众面临的困难与高频听力损失对安静环境中言语感知的众所周知的影响有关，也与听力图无法预测的时间处理能力下降有关，这种下降导致在复杂、嘈杂环境中听力下降。我们还讨论了研究解释的问题；例如，研究人员和临床医生需要警惕听力损失程度和年龄之间经常存在的混淆。相对于老年人与其声学环境之间的相互作用，讨论了听觉言语处理中与年龄相关的变化对未来实践和研究的影响。
