参考答案

答案解析

根据题干中的selective sound patterns和noisy environment定位到原文第六段第一句和第七段第一句。
推理判断题。由第六段第一句可知，科学研究表明，当人听到某种声音时，由此产生的脑波与声波具有物理相似性。此外，根据第七段第一句可知，对于没有经过音乐训练的人来说，他们形成这种脑波模式的能力会随背景噪音的增强而下降。由此推断，音乐家因经过专门音乐训练，他们在嘈杂背景中具有能听到特定声音模式的能力，因此C是本题答案。A“因为他们下意识地训练耳朵熟悉这些声音模式”、B“因为他们的大脑已经过训练，即在嘈杂的背景中识别声音模式”和D“因为他们经过训练的耳朵对特定的声音模式非常敏感，无论它们在哪里出现”均是对原文的曲解，故排除。
