概括

一种新的线性模式点击试验可以快速,可靠地测量人类的对侧介质橄耳反射 (MOCR). 这一进步对于诊断听觉条件和制定人口规范至关重要.

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
临床听力学临床听力学

背景情况:

反侧介质橄耳反射 (MOCR) 的强度是各种听觉条件的潜在指标.
目前用于测量MOCR的方法由于缺乏快速,准确和可靠的测定和设备,因此在临床上不可行.

研究的目的:

为了比较早期的非线性模式声测试与新的线性模式点击测试来测量MOCR.
为了扩展改进的测试,使用专门建造的双声硬件平台与前向压力水平 (FPL) 校准.

主要方法:

进行过渡唤起的音声发射 (TEOAE) 测试,并没有对应的MOCR唤起噪声.
标准化MOCR强度 (MOCR%) 从TEOAE反应中计算出来.
进行了两个实验:一个比较声和点击刺激,另一个使用双耳系统与FPL校准.

主要成果:

线性模式点击试验实现了98%-100%的与测量变量的区分,而非线性模式声则达到73%.
对于线性模式的点击,MOCR的检测性和可靠性更高.
稳定的结果在每只耳朵大约2分钟内得到.

结论:

线性模式点击试验可以快速提供可测量,可靠和稳定的TEOAE和MOCR结果.
该试验适用于临床和实地研究,以建立规范,确定诊断模式,并确定听觉条件的风险概况.

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...
