助听器技术在过去十年中有了显著的进步，特别是在对动态背景噪声的适应性方面。然而，尽管有这些进步，助听器用户仍然报告在背景噪音中听力困难，并且难以适应放大的音质。这些困难可能部分来自于目前的助听器安装方法，这些方法主要侧重于提高可听性和管理环境噪声。这些方法没有考虑到这样一个事实，即声音是沿着听觉系统从耳蜗到听觉皮层进行处理的。老年人是助听器佩戴者的最大群体；然而，众所周知，老年人在中央听觉系统的时间分辨能力方面存在缺陷。在此，我们回顾了支持使用听觉脑干对复杂声音的反应（cABR）来评估老年人噪音听力困难和听觉训练效果的证据。
Hearing aid technology has improved dramatically in the last decade, especially in the ability to adaptively respond to dynamic aspects of background noise. Despite these advancements, however, hearing aid users continue to report difficulty hearing in background noise and having trouble adjusting to amplified sound quality. These difficulties may arise in part from current approaches to hearing aid fittings, which largely focus on increased audibility and management of environmental noise. These approaches do not take into account the fact that sound is processed all along the auditory system from the cochlea to the auditory cortex. Older adults represent the largest group of hearing aid wearers; yet older adults are known to have deficits in temporal resolution in the central auditory system. Here we review evidence that supports the use of the auditory brainstem response to complex sounds (cABR) in the assessment of hearing-in-noise difficulties and auditory training efficacy in older adults.
