对于儿童来说，学习往往发生在背景噪音的存在下。因此，越来越希望改善儿童对噪声中的目标信号的访问。鉴于成年音乐家的感知和神经语音噪声增强，我们询问是否存在类似的效果在音乐训练的儿童。我们评估了音乐家和非音乐家儿童在噪音中对语音的感知和皮层下处理以及相关的认知能力，这些能力与各种总体因素相匹配。结果表明，音乐家的优势，在噪声中处理语音是目前在关键的发展年。通过听觉工作记忆与注意力和听觉脑干反应特性之间的相关性，我们提出音乐家的感知和神经增强是由训练增强的认知能力以自上而下的方式驱动的。我们的研究结果可能会被专业人士认为是在基于语言的学习缺陷，这往往是其特点是穷人的语音感知噪声的补救。
For children, learning often occurs in the presence of background noise. As such, there is growing desire to improve a child’s access to a target signal in noise. Given adult musicians’ perceptual and neural speech-in-noise enhancements, we asked whether similar effects are present in musically-trained children. We assessed the perception and subcortical processing of speech in noise and related cognitive abilities in musician and nonmusician children that were matched for a variety of overarching factors. Outcomes reveal that musicians’ advantages for processing speech in noise are present during pivotal developmental years. Supported by correlations between auditory working memory and attention and auditory brainstem response properties, we propose that musicians’ perceptual and neural enhancements are driven in a top-down manner by strengthened cognitive abilities with training. Our results may be considered by professionals involved in the remediation of language-based learning deficits, which are often characterized by poor speech perception in noise.
