概括
语音可理解性 (SI) 翻转发生在有听力损失的老年人中,即使有语义上下文. 这项研究发现,在辅助听众中,增加的声音水平对丰富的语境和无语境句子的SI产生了负面影响.
科学领域:
- 听力学 听力学是指听力学.
- 语音科学 语言科学
- 听力健康 听力健康
背景情况:
- 由于可听性,语音可理解性 (SI) 通常会随着声音水平的提高而改善.
- 然而,在高水平时,SI可能会下降,这种现象被称为翻转.
- 以前的研究表明,语义上下文可能会掩盖正常听力听众的翻转.
研究的目的:
- 调查语音可理解性 (SI) 翻转是否发生在有高听力值的老年人中.
- 为了确定语义上下文是否会影响这一群体的翻转.
- 为了检查不同音量级对助听障碍听者的SI的影响.
主要方法:
- 用线性放大测量了两组有听力损失的老年人中的SI分数.
- 用语境丰富和无语境的句子在语音形式的噪音中进行了测试.
- 评估SI在各种音量级别,包括65,75dB SPL,和辅助最舒适的水平 (aMCL) +10dB,和85dB SPL.
主要成果:
- 在两组和两种句子类型中都观察到翻转.
- 在65和75dB SPL时,SI下降了7.1%,无论是丰富的语境还是无语境的句子.
- 在更高的水平 (aMCL +10 dB和85 dB SPL),SI下降了9.3%的无上下文和10.4%的丰富的语境句子.
结论:
- 使用线性放大功率听力损失的听众表现出语音可理解性 (SI) 翻转.
- 这种翻转效应发生在中等到高的噪音水平.
- 有和没有语义上下文的句子材料都容易在这个人群中翻转.

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.

Auditory Perception
1.0K
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...

Auditory Pathway
7.1K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

Perceiving Loudness, Pitch, and Location
942
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...

Chunking and Rehearsal in Sensory Memory
562
Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of...

Sensory Modalities
3.7K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
