概括
带有耳植入器 (CI) 的语言前聋子儿童可以比具有CI的成年人更好地使用语音线索来进行语音感知. 这些孩子表现出类似于正常听力同龄人的能力,突出了对退化声信号的有效使用.
科学领域:
- 听力学 听力学是指听力学.
- 语音和听力科学 语言和听力科学
- 神经科学是一个神经科学.
背景情况:
- 带有耳植入器 (CI) 的后语言聋人成年人与声音特征感知斗争.
- 有限的理解存在关于在语言前聋子儿童使用语音特征与CI.
- 儿童神经可塑性可能会增强或阻碍CI使用者的声学暗示利用.
研究的目的:
- 评估语言前聋子儿童使用CI感知语音线索的能力.
- 评估CI儿童在竞争性语音感知中从声音差异中受益.
- 将CI儿童的语音感知能力与正常听力 (NH) 儿童和CI成年人进行比较.
主要方法:
- 三项实验评估了CI儿童的语音暗示歧视,性别分类,以及受益于目标-面具语音差异.
- 专注于对平均基本频率 (F0) 和声道长度 (VTL) 的感知.
- 对照组包括年龄相等的NH儿童和语后聋的CI成年人.
主要成果:
- 与NH儿童相比,CI儿童的F0和VTL分辨率较低,但比CI成年人敏感度更好.
- CI儿童的声音性别分类权重与NH儿童相似,与CI成年人不同.
- CI儿童证明受益于目标面具声音差异,类似于NH儿童,表现优于CI成年人.
结论:
- 在语言前聋的CI儿童有效地利用退化的F0和VTL线索来感知声音和语音.
- CI儿童在语音暗示利用方面的表现和从语音差异中获益接近NH儿童的表现.
- 研究结果表明,CI儿童的CI表现优于CI成年人,这表明成人CI用户面临的挑战超出了声学线索的潜在因素.

211
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...

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.
