概括
与双边CI (BCI) 用户相比,耳植入物 (CI) 语音感知在单侧聋 (SSD) 中降低. 这表明非植入式耳朵可能会阻碍CI的有效性,需要针对SSD听众提供有针对性的支持.
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 康复 康复 康复
背景情况:
- 单侧耳聋 (SSD) 对听力康复提出了独特的挑战.
- 耳植入物 (CI) 是SSD的一个选择,但与双边CI (BCI) 相比,它们的有效性需要进一步研究.
- 了解语音感知差异对于优化SSD中的CI结果至关重要.
研究的目的:
- 通过比较语音感知来评估耳植入在单侧聋 (SSD) 的疗效.
- 将SSD听众的单耳语音感知与匹配的双侧耳植入物 (BCI) 听众进行比较.
- 确定影响SSD和BCI用户CI性能的因素.
主要方法:
- 55名SSD听众和55名年龄/经验匹配的BCI听众之间的语音感知得分进行了比较.
- 分析包括BCI使用者的匹配耳朵和性能较差的耳朵,控制年龄,自激活以来的时间,CI使用和病因.
- 在顺序植入的BCI听者中,第一和第二种植入物的性能也进行了比较.
主要成果:
- 与BCI用户相比,SSD听众表现出明显较低的CNC语音感知,即使在控制共变量之后.
- 顺序植入的BCI听众在第二个植入的耳朵中显示出明显较差的CNC性能,而不是他们的第一个.
- 这些结果表明,在SSD中CI疗效降低,在顺序BCI使用者中潜在的学习效应或耳朵优势.
结论:
- 与BCI用户相比,SSD听众对CI的语音知觉有所减少,可能是由于非植入耳朵的影响 ("阻塞").
- 连续使用BCI的第二只耳朵的表现较差,这表明人们更依赖于更有经验的,首次植入耳朵.
- 为SSD听众优化CI结果可能需要加强培训和支持策略,以克服对植入物的减少依赖.

Hearing
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.
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.
Interference: Path Lengths
Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Echo
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...

Anatomy of the Ear
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...
Auditory Pathway
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
