The aims of this research proposal are to provide a definitive answer to the question of whether formal musical training is associated with enhanced perception of sound. Musicians have been reported to possess enhanced auditory processing of sounds both in quiet and in noise – a result of processes that may begin as early in the auditory pathway as the cochlea itself. These enhancements may underlie improved abilities to understand speech-in-noise, and because of their profound implications, these studies have generated tremendous interest. However, many of the conclusions were based on studies that had i) relatively few participants, ii) mostly adult participants and iii) no assessment of audiometric or cochlear function in the extended high-frequency (EHF) ranges. These proposed experiments are aimed to remedy these deficiencies by recruiting 150 youth musicians, and assessing both audiometric and cochlear EHF regions. Interestingly, even in people with clinically normal hearing thresholds there are differences in hearing in noise abilities. In fact, while there is no clear relationship between normal standard thresholds (0.25-8kHz) and hearing in noise abilities, there is a proposed relationship between extended high-frequency (EHF) hearing thresholds (8-20 kHz) and improved hearing in noise abilities. In addition to audiometric EHF thresholds, cochlear outer hair cell health can also be assessed non-invasively using distortion-product otoacoustic emissions (DPOAEs) both in the standard and EHF frequency ranges. As mentioned early, most previous studies have sorted their adult participants into “musicians” or “non- musicians” based on years of musical training. Our laboratory has recently shown (in both children and adults) that musical aptitude and musical training significantly predict hearing-in-noise abilities. Our hypothesis is that this `musician advantage' in auditory processing is related to both EHF cochlear function and musical aptitude. For both aims, we will recruit ~150 youth (11-18 years) who are students at The Hochstein School as well as other area youth musicians. The Hochstein School enrolls ~ 715 students/year in this age range in their classes and ensembles, providing a natural recruitment platform to assess these behavioral and physiological measures. The specific aims are to investigate whether the `musician advantage' in auditory processing is related to i) EHF audiometric and cochlear function and ii) musical aptitude. Information gained from these studies in youth musicians will provide a rigorous assessment of whether the `musician advantage' in auditory processing exists for all types of sound, and if this advantage is related to musical aptitude, musical training, and EHF cochlear health. We will also be examining what extent music and speech hearing-in-noise abilities overlap, and will be establishing norms and outcome measures that can be used to assess future music-based interventions.

该研究建议的目的是为是否正式提供一个确定的答案 音乐训练与增强的声音感知有关。据报道，音乐家拥有 在安静和噪音中增强了声音的听觉处理 - 流程的结果可能是 在听觉途径的早期，作为耳蜗本身。这些增强可能是提高能力的基础 这些研究了解了毫无意义的语音，并且由于其深远的影响，这些研究产生了 巨大的兴趣。但是，许多结论是基于i）相对较少的研究 参与者，ii）主要是成年参与者，iii）未评估听力学或人工耳蜗的功能 扩展高频（EHF）范围。这些提出的实验的目的是记住这些缺陷 通过招募150名青年音乐家，并评估听力和人工耳蜗EHF地区。 有趣的是，即使在临床正常听力阈值的人中，噪声的听力也有所不同 能力。实际上，虽然正常标准阈值（0.25-8KHz）和 噪音能力的听力，在扩展高频（EHF）听证会之间存在拟议的关系 阈值（8-20 kHz）和噪声能力的听力提高。除了听众的EHF阈值外， 耳蜗外毛细胞健康也可以使用失真产品进行非侵入性评估 标准和EHF频率范围内的排放（DPOAE）。 如前所述，大多数以前的研究都将其成年参与者分类为“音乐家”或“非 - 基于多年音乐培训的音乐家”。我们的实验室最近显示了（在儿童和成人中） 那种音乐能力和音乐训练可以显着预测毫无意义的能力。我们的假设是 在听觉处理中，这种“音乐家优势”与EHF耳蜗功能和音乐能力均相关。 对于这两个目标，我们将招募约150名青年（11-18岁），他们是霍奇斯坦学校的学生 其他地区青年音乐家。霍奇斯坦学校在这个年龄范围内招收约715名学生/年 课程和合奏，提供自然招聘平台来评估这些行为和生理 措施。具体目的是调查听觉处理中的“音乐家优势”是否是 与i）EHF听力和耳蜗功能以及ii）音乐能力有关。 这些研究从青年音乐家那里获得的信息将对是否进行严格评估 所有类型的声音都存在听觉处理中的“音乐家优势”，如果此优势与 音乐才能，音乐训练和EHF人工耳蜗健康。我们还将研究音乐的程度和 语音听力噪声的能力重叠，并将建立可以是的规范和结果措施 用于评估未来基于音乐的干预措施。
