概括
骨传导听力器 (BCD) 没有改善单侧声的儿童的群体空间听力. 然而,BCDs对缺乏无助声音定位的儿童有好处,这表明个性化的好处.
科学领域:
- 听力学 听力学是指听力学.
- 儿科耳鼻喉科 儿科耳鼻喉科
- 语音和听力科学 语言和听力科学
背景情况:
- 先天性单侧声会导致听力困难,特别是在多个声音源的情况下,尽管一只耳朵的听力正常.
- 骨传导装置 (BCD) 可能会改善空间听力,但益处因人而异,测试条件通常与日常生活不同.
- 有限的知识存在于使用BCD的单边听力形症儿童的语音识别和声音定位.
研究的目的:
- 为了研究在噪音中的语音识别和横向声音定位在患有单边听力的儿童中.
- 评估单方面BCD放大对这些听觉技能的影响.
- 探索听力损失程度和适配时的年龄对BCD效益的影响.
主要方法:
- 使用了一个主题内,重复措施的设计.
- 11名儿童 (平均年龄为7.9岁) 患有单边声.
- 听力技能被测试了和没有单方面BCD放大.
主要成果:
- BCD放大没有对水平声音定位精度产生负面影响.
- 语音识别分数显示了显著的个体间变异性,没有从BCDs获得的群体级益处.
- 没有辅助的声音局部化较差的儿童表现出更大的BCD益处;没有辅助的局部化改善了耳道耳道的听力值.
结论:
- 单边BCD放大并没有为患有单边声的儿童的空间听力或语音识别带来群体益处.
- 观察到个性化的好处,特别是在没有辅助本地化能力较差的儿童中.
- 需要对更大样本进行进一步的研究,以了解关耳中的残留听力对定位线索的作用.

01:17Auditory Perception
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 cochlea, a...
01:21Perceiving 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 identifying...
