概括

耳植入物 (CI) 的光谱降解使得声音看起来更消极,更不令人兴奋. 这通过减少对环境声音的情绪反应的范围来影响听觉情绪体验.

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.
情感感知情感感知情感感知

背景情况:

耳植入物 (CI) 改变声信号,可能会影响用户对声音的情感体验.
来自CIs的光谱降解可能会影响环境声音在情感上是如何被感知的.

研究的目的:

为了评估CI模拟的光谱降解对情绪价值和兴奋的影响.
了解改变的听觉信号如何影响对环境声音的情绪反应.

主要方法:

听力正常的参与者听取了光谱降解 (语音编码) 和全频谱环境声音.
参与者在两种声学条件下对30种情感唤起的声音的价值和唤起进行了评分.

主要成果:

与全频谱声音相比,光谱降低的声音引起的极端情绪反应较小.
声代码刺激被认为比它们的全频谱对应物更负面,更不令人兴奋.

结论:

CI光谱退化压缩了声音诱导的情绪范围,独立于听力损失.
研究结果表明,CIs中的光谱过可以改变对环境声音的情感感知.

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
