This project will determine whether formal musical training is associated with enhanced neural processing and perception of sounds, including speech in noisy backgrounds. Music forms an important part of the lives of millions of people around the world, and it is one of the few universals shared by all known human cultures. Yet its utility and potential evolutionary advantages remain a mystery. This project will test the hypothesis that early musical exposure has benefits that extend beyond music to critical aspects of human communication, such as speech perception in noise. In addition, the investigators will test whether early musical training is associated with less severe effects of aging on the ability to understand speech in noisy backgrounds. Degraded ability to understand speech in noise is a common complaint among older listeners and hearing loss has been shown to be associated with social isolation and more rapid cognitive and health declines. If formal musical training is shown to affect improved perception and speech communication in later life, the outcomes could have a potentially major impact on quality of life,Earlier studies have suggested relationships between early musical training and improved auditory neural processing and perception, but the studies' impact has been limited by small sample numbers and inconsistent methods between different studies. This project will test a large number of participants (N=360) with uniform recruitment criteria and testing protocols across six different sites. Measures will include the neural frequency following response (FFR) to speech sounds, behavioral frequency selectivity, speech perception in noise, speech perception against a background of competing talkers, pitch discrimination, and auditory masking. The participants will also complete other assessments, including a personality inventory questionnaire, a profile of musical perception skills, a spatial reasoning test to assess general cognitive ability, as well as a background questionnaire to determine socio-economic status, education, and musical background. Participants will be selected to span a wide range of ages and musical experience. The neural data and the speech perception measures will be related to factors of musical training, such as the number of years of musical training and the age at which musical training began. Scientific rigor will be assured by preregistering the study and the analyses and by making the data and analysis code publicly available via a dedicated website.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将确定正式的音乐训练是否与增强的神经处理和声音感知有关，包括在嘈杂背景下的讲话。音乐是全世界千百万人生活的重要组成部分，是所有已知人类文化共有的少数共性之一。然而，它的效用和潜在的进化优势仍然是一个谜。这个项目将测试这样一个假设，即早期音乐接触的好处不仅限于音乐，还包括人类交流的关键方面，比如对噪音的语音感知。此外，研究人员将测试早期音乐训练是否与年龄增长对嘈杂背景下理解语言能力的影响有关。在噪音中理解语言的能力下降是老年听众的常见抱怨，听力损失已被证明与社会孤立、认知能力和健康状况的迅速下降有关。如果正式的音乐训练被证明可以改善晚年的感知和语言交流，那么结果可能对生活质量产生潜在的重大影响。早期的研究表明，早期音乐训练与听觉神经处理和感知的改善之间存在关系，但这些研究的影响受到样本数少和不同研究之间方法不一致的限制。该项目将在6个不同的地点以统一的招募标准和测试协议测试大量参与者（N=360）。测量将包括语音的神经频率跟随反应（FFR）、行为频率选择性、噪声中的语音感知、竞争说话者背景下的语音感知、音高辨别和听觉掩蔽。参与者还将完成其他评估，包括性格调查问卷、音乐感知技能概况、评估一般认知能力的空间推理测试，以及确定社会经济地位、教育程度和音乐背景的背景调查问卷。参加者将被挑选为跨越广泛的年龄和音乐经验。神经数据和语音感知测量将与音乐训练的因素有关，如音乐训练的年数和音乐训练开始的年龄。通过预先注册研究和分析，并通过专门的网站公开数据和分析代码，将确保科学严谨性。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
