概括
带有耳植入物 (CI) 的孩子在噪音中说得更大声和更长时间,与正常听力同龄人不同,他们更适应声. 这些发现影响了课堂沟通策略.
科学领域:
- 语音语言病理学 语言病理学
- 审计处理 审计处理
- 儿科听力学 儿科听力学
背景情况:
- 带有耳植入器 (CI) 的儿童在像教室这样的杂环境中面临沟通挑战.
- 伦巴德效应,一种对噪音的声响,影响了语音的产生.
- 了解这些影响对于改善CI用户在现实环境中的沟通至关重要.
研究的目的:
- 为了研究罗姆巴德效应的语音强度和持续时间的儿童与CI对比正常听力 (NH) 的孩子.
- 分析语音形噪声 (SSN) 和具有反响的SSN对母音产生的影响.
- 为了确定两个群体之间的声音补偿策略的差异.
主要方法:
- 与7名CI儿童和7名NH儿童 (7-12岁) 进行了比较.
- 在安静,SSN和SSN+反响条件下测量压力元音的强度和持续时间.
- 分析了伦巴德效应,通过比较声学环境中的语音产生.
主要成果:
- 与NH儿童相比,患有CI的儿童总体上产生了更大声的压力元音.
- 两组都增加了噪音的强度,NH儿童的反响进一步增加.
- 患有CI的儿童在安静和SSN中产生了更长的压力元音,但随着反响,这种效应减少了.
结论:
- 与NH儿童相比,患有CI的儿童表现出不同的龙巴德效应模式,特别是在响应声时.
- 在CI使用者中,更高的强度和持续时间可能有助于在噪音中感知语音.
- 这些发现对优化CI儿童在杂的教育环境中的沟通策略有意义.

The Cochlea
44.8K
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.

The Auditory Ossicles
1.6K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
