概括
对于耳植入物 (CI) 和助听器 (HA) 用户来说,噪音中的语音感知是具有挑战性的,特别是在调制噪音的情况下. 在所有测试条件下,听力损失显著恶化语音接收值 (SRTs).
科学领域:
- 听力学和听力科学 听力学和听力科学
- 神经科学是一个神经科学.
- 生物医学工程 生物医学工程
背景情况:
- 耳植入物 (CIs) 恢复听力,但与正常听力 (NH) 相比,在噪音中与语音感知作斗争.
- 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.
- 在噪音中理解语音对于CI和HA用户的生活质量至关重要.
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IC使用者的表现与年龄相匹配的HA使用者和NH个体.
- 评估不同类型的噪音 (连续与调制) 对语音接收值 (SRT) 的影响.
主要方法:
- 参与者包括19名双模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在两个条件下测量了语音接收值 (SRTs):S0N0 (语音和从前面的噪声) 和多源噪声场 (MSNF).
- 使用了连续的奥尔登堡噪声 (Ol-noise) 和振幅调制的Fastl噪声 (Fastl-noise).
主要成果:
- 在所有疾病中,随着听力损失的增加,SRT显著恶化.
- 在连续和调制噪声条件下,双莫道尔IC使用者比年轻NH个体的SRT明显更差.
- 在HA或双模CI组中没有观察到"间隙听"的好处;调制噪声 (Fastl噪声) 导致比连续噪声 (Ol噪声) 更糟糕的SRT.
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中严重受损.
- 比莫达尔IC使用者在噪音中的语音感知方面表现出重大挑战,特别是在调制环境中.
- 听力损失是影响各种噪音条件下语音接收值的主要因素.

Auditory Perception
385
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
241
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

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...
