概括
听觉感知训练并没有显著改善经验不丰富的语音语言病理学家 (SLP) 的超鼻分类. 一个SLP在培训后表现出对黄金标准的同意程度增加,这表明进一步研究可能带来潜在的好处.
科学领域:
- 语音语言病理学 语言病理学
- 头骨面部异常 头骨面部异常
- 声学分析 声学分析
背景情况:
- 超鼻是个人的一个常见的语言障碍 裂口唇和 palatal.
- 对高鼻度的准确感知分类对于有效的语言治疗至关重要.
- 没有经验的语音语言病理学家 (SLPs) 可能需要专门的培训来提高分类准确性.
研究的目的:
- 评估听觉感知训练对缺乏经验的SLP在裂口口腔扬声器中分类超鼻的能力的影响.
- 将个人SLP分类与训练前和训练后的黄金标准进行比较.
主要方法:
- 三位没有经验的语音治疗师使用四分级评价24个语音样本 (不同程度的超鼻性).
- 在听觉感知训练之前和之后进行了评估,其中包括样本和即时反.
- 使用卡帕协议指数分析了采用黄金标准评估的协议.
主要成果:
- 总体而言,正确分类百分比并没有显著改善培训后的情况.
- 在培训后,所有三个SLP都观察到与黄金标准的显著关联和协议.
- 一个SLP显示出对缺席和轻度超鼻症的同意程度增加,卡帕指数更高.
结论:

01:17Auditory Perception
363
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...

01:21Perceiving 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...

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.

01:01Perception 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...
