这项新研究首次通过年龄谱检测了音乐家和未接受过音乐训练人的听力，受测人的年龄从18岁到91岁。研究中,74名音乐家(年龄19-91岁)和89名未受过音乐训练的普通人(年龄18-86)参与了一系列的听觉评估。

A musician was defined as someone who started musical training by the age of 16, continued practicing music until the day of testing, and had at least six years of formal music lessons. Non-musicians in the study did not play any musical instrument.

音乐家是那些从16岁开始学习音乐、持续练习直到测试的当天、并且有至少有6年正规音乐课训练的那类人。未受过正规音乐训练的人则从未演奏过任何乐器。

The subjects sat in a soundproof room and completed four auditory tasks and results revealed musicians showed a clear advantage over non-musicians and this advantage gap widened as both groups got older. By age 70, the average musician was able to understand speech in a noisy environment as well as an average 50 year old non-musician, suggesting that lifelong musicianship can delay this decline by 20 years.

被测试者在隔音室里完成4个听力测试，结果显示音乐家的听力清晰程度要好于普通人，而且年龄越大，优势就越明显。一般来说，70岁的音乐家可以跟50岁的普通人一样在喧闹的环境下听讲演，这也就是说，终身音乐才能使人的耳朵推迟衰退20年。
