概括

中间橄耳耳系统在几秒钟内显示了短期的活动. 更强烈的感官功能可能有助于在杂的环境中理解语音.

科学领域:

听觉神经科学听觉神经科学
耳声波排放耳声波排放耳声波排放
人的听觉生理学人的听觉生理学

背景情况:

中间橄耳耳 (MOC) 效应系统调节耳敏感度.
暂时唤起的耳声发射 (TEOAEs) 是对耳外毛细胞功能的客观测量.
了解MOC的不同系统动态对于听觉感知研究至关重要.

研究的目的:

量化对人类TEOAEs的MOC抑制的短期积累.
为了研究不同的对侧抑制剂持续时间如何影响MOC抑制大小.
检查MOC效应抑制强度和语音在噪音中的表现之间的关系.

主要方法:

使用主体内设计来评估TEOAE抑制.
使用了2秒,4秒和6秒的对侧宽带噪声爆发.
收集了行为语音与噪音 (WIN测试) 的测量结果.

主要成果:

随着对侧噪声持续时间的延长 (高达6s),MOC抑制大小的增加,这表明短期积累.
在耳朵之间没有观察到抑制的显著差异.
虽然抑制强度与语音识别值没有相关性,但它与更的心理测量斜率有关.

结论:

中间橄耳活动在几秒钟内呈现出时间依赖的积累.
通过更强的MOC抑制来表明增强的感官功能,可以支持在具有挑战性的声学环境中适应性听力.

关键词:

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...
