印度古典音乐培训,特别是打击乐手的培训,增强了语音在噪音中的感知,并减少了在具有挑战性的听觉条件下倾听的努力. 这种音乐家优势在难以听取的场景中最为明显.
科学领域:
- 听觉神经科学 听觉神经科学
- 精神声学是一种精神声学.
- 音乐感知 音乐感知
背景情况:
- 音乐训练与语言处理网络中的基于经验的可塑性有关.
- 音乐对听力努力 (LE) 对在退化环境中的语音的影响还没有得到充分的研究.
研究的目的:
- 调查印度古典音乐培训对语音噪音 (SIN) 感知的影响.
- 评估音乐训练在具有挑战性的听力条件下对听力努力 (LE) 的影响.
主要方法:
- 一个准实验性的设计涉及16名打击乐手,17名非打击乐手和26名非音乐家 (年龄在18-35岁,听力正常).
- 用音乐感知技能迷你档案 (Mini-PROMS) 来评估音乐能力.
- 语音噪音 (SIN) 感知和听力 (LE) 测量使用标准化测试和学生计在不同的信号噪音比率 (SNRs).
主要成果:
- 与非打击乐手相比,打击乐手在特定的Mini-PROMS子集 (调,速度) 中表现优越.
- 与非打击乐手和非音乐家相比,打击乐手表现出明显更好的SIN感知,并降低了LE,在单词上为-5dB SNR,在句子上为0dB和-5dB SNR.
结论:
- 打击乐手表现出最显著的优势解码语音在噪音下降的倾听力度.
- 观察到一个明确的利益等级:打击乐手>非打击乐手>非音乐家,特别是在苛刻的听力环境中.
