概括

单侧耳聋 (SSD) 患者表现出不同的声音局部化能力,使用活跃的穿皮骨传导植入物 (atBCI). 一些人从设备中受益,特别是在高频率,而另一些人则表现出最小的改善.

科学领域:

听力学听力学是指听力学.
神经科学是一个神经科学.
生物医学工程生物医学工程

背景情况:

单侧耳聋 (SSD) 显著影响空间听力和声音定位.
活跃的穿皮骨传导植入物 (atBCI) 是SSD听力恢复的潜在解决方案.
了解atBCI在SSD中的声音定位方面的有效性对于患者管理至关重要.

研究的目的:

在使用atBCI的SSD个体中评估声音定位的准确性.
为了比较SSD患有atBCI的患者与对照组的表现.
评估atBCI对空间听觉的主观益处.

主要方法:

一项前性病例控制研究在三级推中心进行.
参与了10名患有atBCI的SSD患者和10名对照患者.
声音本地化被评估使用一个24扬声器阵列在一个半无声室与宽带和窄带噪声刺激.

主要成果:

对于宽带和低频窄带噪声,SSD患者的声音定位与对照组相比明显差.
在SSD患者的辅助和无辅助条件之间没有观察到本地化的显著差异.
在SSD队列中,定位能力有所不同,其中一些显示了设备在高频率的改进.

结论:

患有atBCI的SSD患者的声音局部化表现出双模分布.
一些个人经历了保留但没有改善的局部化,特别是在高频率时,与atBCI.
其他显示最小的本地化能力和设备没有显著的好处.

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.
