概括
耳植入物 (CI) 可以恢复单侧耳聋 (SSD) 的声音定位,但可能无法完全改善听觉空间歧视. 康复可以提高这些听觉技能.
科学领域:
- 神经科学是一个神经科学.
- 听力学 听力学是指听力学.
- 生物医学工程 生物医学工程
背景情况:
- 空间听力依赖于双声输入;不对称的听力损害了准确性.
- 单侧耳聋 (SSD) 对空间听力提出了挑战.
- 单侧耳植入物 (CI) 可以帮助补偿SSD.
研究的目的:
- 通过使用单方面CI来调查SSD患者的听觉空间歧视.
- 为了比较CI用户和正常听力听众之间的空间区分性能.
- 探索声音定位和空间区分能力之间的关系.
主要方法:
- 在18名CI-SSD参与者和120名正常听力 (NH) 听众中测量了最小可听角度 (MAA).
- 低频 (LF) 和高频 (HF) 噪声爆发在不同的方向呈现.
- MAA值与本地化性能相关.
主要成果:
- 8名CI-SSD参与者表现良好,10名表现不佳.
- 较差的性能更常见于LF信号和较小的空间分离 (4°,30°).
- 在一些参与者中,CI侧的局部化和MAA表现与NH侧可比.
结论:
- CI有效地恢复了声音本地化,但并不总是听觉空间歧视.
- 听觉空间区分能力可以通过康复训练.
- 需要进一步的研究来优化CI康复的空间听力.

Perceiving Loudness, Pitch, and Location
217
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...

Auditory Perception
341
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...
