概括
带有耳植入器 (cCI) 的语言前聋子儿童表现出类似成人的光谱处理能力. 在cCI中,频率分辨率 (FR) 与语音识别相关,这表明FR作为年轻听众的耳植入器疗效的衡量标准.
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.
- 语音语言病理学 语音语言病理学
背景情况:
- 耳植入器 (CI) 在语前聋婴儿的目的是发展口语,但结果各不相同.
- 在幼儿中评估CI疗效是具有挑战性的,因为语音感知测试的局限性.
- 在语后聋的成年人中,语音感知与光谱分辨率有关,包括频率分辨率 (FR) 和光谱调制灵敏度 (SMS).
研究的目的:
- 调查带有耳植入器 (cCI) 的语言前聋儿童的光谱分辨能力 (FR和SMS).
- 将cCI中的FR和SMS与语后聋成人 (aCI) 进行比较.
- 在cCI中确定光谱分辨率和语音识别 (母音和辅音) 之间的相关性.
主要方法:
- 一个涉及亲自,展位测试的横截面研究.
- 频谱波纹区分 (SRD) 任务测量来自频谱调制转移函数的FR和SMS.
- SRD性能与元音和辅音识别的测量之间的相关性分析.
主要成果:
- 包括15名cCI和13名aCI参与者.
- 在cCI和aCI组之间,FR和SMS被发现是相似的.
- 改善的FR与cCI中的大多数措施中更好的语音识别有关.
结论:
- 具有CI的语言前聋子儿童表现出类似成人的FR和SMS.
- 在cCI中,FR与语音识别能力相关.
- 在儿童使用者中,FR可作为评估耳植入物疗效的有价值指标.

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...

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...
