反侧向信号路由 (CROS) 助听器通过损害单侧耳聋的 monaural 线索来破坏单侧耳聋的空间听力. 这导致局部精度降低,水平和垂直平面上的努力增加.
科学领域:
- 听觉神经科学 听觉神经科学
- 听力学 听力学是指听力学.
- 人类的感知 人类的感知
背景情况:
- 单侧耳聋的个体通常使用单声线索适应空间听力.
- 反侧向信号路由 (CROS) 是单侧耳聋的常见康复策略.
- 对于CROS设备对关键的单声本地化线索的影响仍然不太了解.
研究的目的:
- 为了研究CROS助听器如何影响空间定位在近视线和高度.
- 评估CROS设备对单声定位线索的破坏.
主要方法:
- 在10名正常听觉的成年人中,在三个条件下测试了定位:正常听觉,单侧耳塞和单侧耳塞用CROS助听器.
- 使用泡耳塞模拟单耳听力.
- 刺激包括从水平和垂直平面的不同位置呈现的高通噪声爆发.
主要成果:
- 单边耳塞导致了良好的海拔定位,但是一种亚齐木斯偏差.
- 使用CROS设备显著降低了高度定位性能 (增益降低,r2低).
- 亚齐木斯局部化在CROS中恶化,反应时间和可变性增加.
结论:
- 克罗斯助听器会破坏基本的单声谱和水平线索.
- 这种干扰会对水平和垂直的声音定位造成重大损害.
- 随着CROS设备的使用,定位变得更加费力,由更长的反应时间和更高的响应可变性表明.

Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
