概括

长期单侧聋 (SSD) 影响声源定位 (SSL) 根据受影响的耳朵不同. 右侧的SSD可能会从单边耳植入 (UCI) 中获得更多的好处,以改善SSL.

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.
耳鼻喉科耳鼻喉科耳鼻喉科

背景情况:

单侧耳聋 (SSD) 对听觉感知提出了独特的挑战.
了解SSD横向性对声音源本地化 (SSL) 的影响对于有效干预至关重要.
SSD对中央审计处理的长期影响需要进一步调查.

研究的目的:

为了研究右对左长期SSD对SSL的影响.
评估对SSD患者进行干预的必要性.
在SSD中分析单边耳植入 (UCI) 的SSL治疗效果.

主要方法:

在25名SSD患者,11名UCI患者和30名正常听力 (NH) 参与者中评估了SSL能力.
使用平均根平均平方 (RMS) 误差值来量化SSL性能.
在SSD (左与右),UCI和NH组之间比较SSL性能.

主要成果:

听力正常的参与者表现出优越的SSL (RMS误差:4.27° ± 2.66°).
在SSD患者中,SSL显著受损 (RMS误差:52.26° ± 20.25°).
与右方SSD组相比,左方SSD组的SSL能力更好;在右方SSD和UCI组之间没有发现显著差异.

结论:

长期的SSD对中央听力皮层的影响不同,取决于聋的侧面.
与SSD患者的左侧UCI相比,右侧UCI可能为SSL提供更大的好处.
这些发现强调了在SSD治疗决策中考虑横向性的重要性.

Perceiving Loudness, Pitch, and Location

Perceiving Loudness, Pitch, and Location

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Echo

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,...

Hearing

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.
