背景情况:

空间定向是一个关键的执行功能,与听觉和视觉系统密切相关.
有效的审计组织对于日常活动,环境意识和学习至关重要.
耳植入物 (CI) 的目的是恢复听力,但它们在复杂的声学环境中的有效性需要进一步研究.

研究的目的:

评估噪音和反响对小儿耳植入物使用者的听觉定位和表现的影响.
为了比较CI用户在静音,噪音和反响条件下的性能.
确定CI用户在不利的声学环境中面临的具体挑战.

主要方法:

研究了一组34名儿科双边CI使用者 (8-10岁) 患有深度神经感官听力损失的队列.
参与者接受了听力学测试,语言评估和声音本地化任务,在不同噪音和反响水平下进行.
使用SPSS21进行前性数据收集和分析.

主要成果:

在安静条件下,CI用户表现出良好的声音定位.
在特定角度 (-10dB SNR,0.6-0.9s反响) (p ≤ 0.005) 观察到局部化声音的显著困难.
连续CI使用者表现出改变的表现,信号与噪声比率和反响的变化 (p <0.05).

结论:

儿科CI使用者在理解语音和定位声音方面面临相当大的挑战,在像学校这样的杂和反响的环境中.

Perceiving Loudness, Pitch, and Location

Perceiving 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...

The Cochlea

The 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.
