概括
使用耳植入物 (CI) 和助听器 (HA) 进行双方式听觉,与单方面CI使用相比,显著改善了儿童在噪音中的普通话语音识别. 这种好处对于在噪音环境中导航的语言前失聪儿童至关重要.
科学领域:
- 听力学 听力学是指听力学.
- 语音科学 语言科学
- 神经科学是一个神经科学.
背景情况:
- 对于耳植入物 (CI) 用户来说,词汇音调识别是一个挑战,特别是在杂的环境中.
- 双方式听觉,通过助听器 (HA) 将CI与对侧声学听觉相结合,可以增强听觉感知.
- 使用CI的语言前聋子儿童需要有效的听力康复策略.
研究的目的:
- 为了评估单边CI与双模听力在语言前聋子儿童中普通话语音识别.
- 为了在稳定状态噪声 (SSN) 和多说话者声 (TTB) 条件下比较性能.
- 评估不同信号噪声比 (SNR) 对音色感知的影响.
主要方法:
- 研究了53名在语言前失聪的普通话儿童,他们患有智能障碍.
- 参与者被分为单边CI用户 (n=22) 和双模听力用户 (n=31).
- 在安静和噪音 (SSN,TTB) 中测试了四个SNR (-6,0,+6,+12 dB) 的音调识别.
主要成果:
- 与单方面CI使用相比,双向听力显著改善了噪音中的音色识别.
- 在SSN和TTB条件下,在较高的SNR中观察到显著差异.
- 对于这两组人群来说,多人说话的喋喋不休 (TTB) 呈现出比SSN更大的掩盖效应.
结论:
- 患有CI的前语言聋儿童在噪音中遇到语音感知困难.
- 双模听力,当残留听力允许时,在具有挑战性的声学环境中为音色识别提供了显著的好处.
- 早期干预和适当的助听器使用对于改善CI用户的听觉结果至关重要.

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
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...
