在复杂环境中理解语音的能力取决于大脑保持语音信号精确定时特性的能力。与听力相关的时间处理能力下降可能导致老年人在具有挑战性的听力条件下出现沟通困难。本研究旨在探讨频率辨别训练对听觉时间加工的影响。一项双盲、随机对照设计将77名年轻听力正常、老年听力正常和老年听力受损的听众分配到两个治疗组之一：实验组（100和300 Hz脉冲串的频率辨别）和主动对照组（噪声中的音调检测）。所有的听众在训练前和训练后的会议期间进行了评估，使用感知率歧视的100-，200-，300-和400-Hz带限脉冲串和听觉稳态反应（ASSR）相同的刺激。训练泛化进行了评估，使用几个时间处理措施和句子识别测试，包括时间压缩和混响语音刺激。结果表明，训练组与训练组之间的交互作用，用于训练频率（100和300 Hz）的感知和ASSR测试，这是由训练组比活动对照组更大的改善所驱动的。此外，后测试率歧视的老年听众达到的水平，相当于那些年轻的听众在前测试。泛化观察到显着改善率歧视的未经训练的频率（200和400赫兹）和性能变化之间的相关性率歧视和句子识别的混响语音。此外，非听觉抑制/注意力表现预测了与训练相关的速度辨别能力的改善。总的来说，结果表明，听觉训练的潜力，部分恢复时间处理在老年听众和突出的作用，认知功能在这些收益。
The ability to understand speech in complex environments depends on the brain’s ability to preserve the precise timing characteristics of the speech signal. Age-related declines in temporal processing may contribute to the older adult’s experience of communication difficulty in challenging listening conditions. This study’s purpose was to evaluate the effects of rate discrimination training on auditory temporal processing. A double-blind, randomized control design assigned 77 young normal-hearing, older normal-hearing, and older hearing-impaired listeners to one of two treatment groups: experimental (rate discrimination for 100- and 300-Hz pulse trains) and active control (tone detection in noise). All listeners were evaluated during pre- and post-training sessions using perceptual rate discrimination of 100-, 200-, 300-, and 400-Hz band-limited pulse trains and auditory steady-state responses (ASSRs) to the same stimuli. Training generalization was evaluated using several temporal processing measures and sentence recognition tests that included time-compressed and reverberant speech stimuli. Results demonstrated a session × training group interaction for perceptual and ASSR testing to the trained frequencies (100 and 300 Hz), driven by greater improvements in the training group than in the active control group. Further, post-test rate discrimination of the older listeners reached levels that were equivalent to those of the younger listeners at pre-test. Generalization was observed in significant improvement in rate discrimination of untrained frequencies (200 and 400 Hz) and in correlations between performance changes in rate discrimination and sentence recognition of reverberant speech. Further, non-auditory inhibition/attention performance predicted training-related improvement in rate discrimination. Overall, the results demonstrate the potential for auditory training to partially restore temporal processing in older listeners and highlight the role of cognitive function in these gains.
