概括
与正常听力个体相比,耳植入物 (CI) 和助听器 (HA) 用户在噪音中的语音感知显著受损. 调制噪声进一步加剧听力困难,特别是对于那些有听力损失的人.
科学领域:
- 听力学 听力学是指听力学.
- 神经科学是一个神经科学.
- 语音和听力科学 语言和听力科学
背景情况:
- 耳植入物 (CI) 在安静的情况下提供了良好的语音感知,但在噪音中与语音扎.
- 双向IC配件 (一只耳朵的CI,另一只耳朵的助听器 (HA)) 在噪音中的表现受到残留声学听力的影响.
- 听力损失的严重程度与噪音中的语音感知减少有关.
研究的目的:
- 为了研究双模体IC用户在噪音中的语音感知.
- 为了比较双模体CI用户与年龄相匹配的HA用户和正常听力 (NH) 个体.
- 评估不同噪声条件和不同参与者群体的性能.
主要方法:
- 参与者包括19名双模体IC使用者,39名HA使用者,40名老年NH受试者 (60-90岁) 和14名年轻NH受试者.
- 使用奥尔登堡句子测试测量语音接收值 (SRTs).
- 使用了两个空间条件 (S0N0和多源噪声场) 和两种噪声类型 (连续的Ol-noise和调制的Fastl-noise).
主要成果:
- 在所有疾病中,随着听力损失的增加,SRTs显著恶化.
- 在连续和调制噪声条件下,双莫道尔CI使用者的表现比年轻NH个体要差.
- 较老的NH个体从间隙听力中获得的益处有限,而HA和双模CI组在调制噪声中没有间隙听力效应,表现更差.
结论:
- 对于有听力损失的人来说,调制噪音中的语音感知比连续噪音更具有挑战性.
- 听力损失的严重程度是影响语音在噪音中的表现的关键因素.
- 双模体IC使用者和HA使用者在杂的环境中面临重大困难,特别是调制噪声.

Auditory Perception
364
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Perceiving Loudness, Pitch, and Location
239
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...

Perception of Sound Waves
4.5K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

The Cochlea
45.2K
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.

Hearing
52.5K
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.
