概括
在耳植入物 (CI) 患者中确定开放场段状反射值 (oSRT) 有助于确定次优适配水平. 许多基于强度等级的CI配件落在正常听力范围之外,可能会影响听力学性能.
科学领域:
- 听力学 听力学是指听力学.
- 生物医学工程 生物医学工程
- 神经科学是一个神经科学.
背景情况:
- 耳植入物 (CI) 配件对于优化听力学性能至关重要.
- 主观的噪音缩放通常用于CI配件,但其在达到最佳刺激水平的准确性仍在争论中.
- 客观的测量,如状反射值,可以提供对合效果的见解.
研究的目的:
- 为了确定在CI患者的开放场地形反射值 (oSRTs),使用主观的噪音评级来安装CI患者.
- 为了将这些oSRT与基于电声梯度反射 (eSRT) 的配件获得的,以正常听力范围为目标的oSRT进行比较.
- 评估oSRT在识别具有潜在低于最佳刺激水平的CI配件方面的实用性.
主要方法:
- 在使用音频处理器时,对50名经验丰富的CI用户的57个耳朵进行了鼓膜阻抗测量.
- 通过通过CI系统的电刺激引起的 stapedius 反应是响应在自由声场中的声学刺激.
- 从基于eSRT的配件的CI患者中建立了oSRT的参考范围.

01:13The Cochlea
45.2K
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.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
