概括
每日耳植入物 (CI) 佩戴时间显著影响成年人的语音感知. 每天佩戴CI10个小时或更长时间会比较短的佩戴时间带来更好的结果.
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.
- 康复医学 康复医学 康复医学
背景情况:
- 耳植入物 (CI) 的性能变化通常归因于手术前的因素.
- 术后因素的影响,例如每天使用设备,需要进一步调查.
研究的目的:
- 研究每日耳植入物 (CI) 佩戴时间对成年接受者的术后语音感知的影响.
- 为了确定预测CI使用一年后性能的关键因素.
主要方法:
- 对158名成年IC使用者的回顾性分析.
- 根据每日CI磨损时间分为两组:<10小时 (n=46) 和≥10小时 (n=112).
- 相关性和回归分析以评估佩戴时间,年龄,听力损失的持续时间和语音感知得分 (CNC Words,AzBio) 之间的关系.
主要成果:
- 每日CI磨损时间与CNC Words (r=0.44) 和AzBio分数 (r=0.37) 都显示出显著的正相关性.
- 回归模型表明,平均佩戴时间和年龄预测了AzBio分数 (R2=0.21),而佩戴时间和听力损失的持续时间预测了CNC分数 (R2=0.28).
- 成年人穿着他们的CI≥10小时/天实现显著更高的语音感知得分相比那些穿着它<10小时/天.
结论:
- 每日平均CI佩戴时间,植入时的年龄和听力损失的持续时间是语音感知结果的重要预测因素.
- 持续和长时间的CI使用 (≥10小时/天) 与增强的语音理解有关.
- 建议早期植入并最大限度地提高每日CI使用量,以获得最佳的术后性能.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:13The 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.
01:11The Auditory Ossicles
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...

01:06Echo
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...
