概括
患有轻度至中度听力损失的儿童由于难以处理听觉调制,因此在噪音中难以说话. 非语言测试可以帮助评估这些挑战,并指导听力康复.
科学领域:
- 听觉神经科学 听觉神经科学
- 语音感知 语音感知
- 儿科听力学 儿科听力学
背景情况:
- 听力损失的儿童在理解言语方面面临重大挑战,特别是在像课堂这样的杂环境中.
- 有效的语音理解依赖于检测和区分光谱-时间听觉信息的能力.
- 调查这些听觉处理技能对于解决听力障碍儿童的教育和沟通困难至关重要.
研究的目的:
- 为了比较轻度至中度听力损失 (MMHL) 儿童与正常听力 (NH) 儿童的听觉光谱时间调制的处理.
- 检查这些群体在噪音中的听觉调制处理和语音感知之间的关系.
- 评估非语言听力测试在评估听力损失儿童的感知困难方面的潜力.
主要方法:
- 一项涉及31名轻度至中度神经感官听力损失 (SNHL) 的儿童和34名正常听力儿童 (8-12岁) 的横截面研究.
- 参与者完成了光谱调制波纹测试 (SMRT),在各种频率的振幅调制检测测试 (AMDTs),以及在噪音中语音感知 (SPiN) 测试 (Word-in-Noise和BKB-SIN).
- 两组之间的表现进行了比较,并分析了测试之间的相关性,包括耳朵之间的比较.
主要成果:
- 患有MMHL的儿童在SMRT,AMDT和SPiN测试中表现明显差于NH儿童.
- 在轻度和中度听力损失类别之间没有发现显著的性能差异.
- 虽然SMRT和AMDT与Word-in-Noise测试没有相关性,但在SMRT和BKB-SIN之间以及在两个组中更高率的AMDT和BKB-SIN结果之间观察到显著的相关性.
结论:
- 患有轻度至中度SNHL的儿童表现出利用光谱和时间调制线索的能力降低,这影响了他们在噪音中的语音理解.
- 非语言光谱和时间调制测试是评估听力损失儿童感知障碍的宝贵工具.
- 这些测试需要最小的认知负载,可以帮助制定听力康复策略.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

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.
