概括
经验丰富的耳植入物 (CI) 用户描述声音质量不同于预期,随着时间的推移",清晰"成为最常见的术语. 这与单侧聋 (SSD) 患者不同,表明CI体验会改变声音感知.
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 (CIs) 可以恢复听力,但声音质量的感知有所不同.
- 了解患者描述的声音质量对于设备优化至关重要.
- 之前的研究使用单侧聋 (SSD) 患者进行声音质量匹配.
研究的目的:
- 确定常规CI患者用来描述声音质量的常用术语.
- 将这些描述符与SSD患者的声学匹配进行比较.
- 探索CI体验如何影响声音质量感知.
主要方法:
- 调查了255名常规CI患者 (先进生物学,耳,MED-EL) 使用25个形容词问卷.
- 在两个时间点收集数据:接近激活 (T1) 和当前使用 (T2).
- 分析了描述器频率,并根据电极阵列长度和CI经验对比了响应.
主要成果:
- 最初 (T1),像"计算机式"",Treble-y"和"金属"这样的描述词是常见的.
- "HiPitched"描述符在具有较短电极阵列的患者中更为频繁.
- 随着时间的推移 (T2),"清晰"成为三分之二的患者的主导描述词,最初的差异正在减少.
结论:
- 传统CI患者的声音质量描述符随着经验的发展而演变.
- 与SSD患者相比,经验丰富的常规CI用户对感知到的声音变化不那么突出.
- 缺乏正常听觉的耳朵样本可能会随着时间的推移影响传统CI用户的感知.

The Cochlea
44.5K
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.

Pulse amplitude and quality
1.6K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

Anatomy of the Ear
7.2K
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...

The Auditory Ossicles
1.6K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
