概括

与没有耳的人相比,有耳的听众在杂的环境中更难理解语音. 这表明 tinnitus 患者对信息掩盖的敏感性增加,即使听力正常.

科学领域:

听觉神经科学听觉神经科学
语音感知语音感知
耳研究研究耳研究

背景情况:

耳与增加的压力,焦虑和生活质量的降低有关.
耳患者经常表现出语音分离能力受损,即使听力值正常.
与事件相关的潜能 (ERP),特别是P3组件,已被用来研究耳的神经相关性.

研究的目的:

调查与 tinnitus 和没有 tinnitus 个体之间的语音接收值 (SRT) 和听觉事件相关潜力 (ERP) 的差异.
为了确定耳声是否会影响在能量和信息掩盖的条件下分离竞争性语音的能力.
探索 tinnitus 语音处理困难的神经基础.

主要方法:

在29名有耳的听众和25名没有耳的听众中测量了SRT和听觉ERP,所有听力都在临床上正常.
通过使用男性目标说话者在语音形状噪音 (能量掩饰) 或使用女性语音掩饰 (信息掩饰) 来评估SRT.
听觉ERP被记录为1kHz与2kHz的频率对比.

主要成果:

与没有耳的听众相比,有耳的听众在竞争性语音 (信息掩盖) 中的SRT明显较差 (p = 0.042).
在语音形式的噪音 (能量掩饰) 中,SRTs没有发现显著的群体差异.
在耳组中,N1和P3 ERP延迟时间显著更长,这表明神经处理速度较慢.

结论:

临床上正常听力和耳的成年人对信息掩盖的敏感性增加,影响复杂的听觉环境中的语音感知.
耳听者的长时间N1和P3延迟表明听力通路的功能发生了变化.
这些发现强调了耳对语音处理的重大影响,即使没有可测量的听力损失.

关键词:

注意力注意力注意力注意力审计唤起了潜在的可能性.这是普通话的普通话.正常的听力正常的听力在P300300中,P300是最重要的.语音感知语音感知声 (Tinnitus) 是一种听力障碍.

Hearing

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.

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...
