概括
脑管峰突出 (CPP) 能够有效地区分史密斯-马格尼斯综合征 (SMS) 患者的声音与神经类型的声音,即使有声音亚和声. 这种声学分析提供了一种强大的方法来识别病态语音特征.
科学领域:
- 语音和听力科学 语言和听力科学
- 神经学 神经学
- 声学分析 声学分析
背景情况:
- 语音是复杂的,受到身体,临床和情绪状态的影响.
- 神经系统疾病可以由于皮质或神经认知变化而改变语音信号.
- 之前的研究将史密斯-马根尼斯综合征 (SMS) 声音与较低的脑管峰突出度 (CPP) 和亚声调联系起来.
研究的目的:
- 为了确定CPP和亚声波是否可以同时区分SMS声音与神经类型声音.
- 分析与SMS声音中的亚和声相吻合的形式轨迹变化.
主要方法:
- 在12个SMS个体中隔离了亚声波对CPP的影响.
- 在亚波区域评估的CPP,使用f0峰值作为基线.
- 同步分析的形式变化与亚的外观.
- 在神经类型和SMS儿童的匹配组之间比较了持续的/a/声调.
主要成果:
- 脑管峰突出 (CPP) 区分了规范和SMS扬声器,即使分隔了亚声波.
- 低音是SMS声音的特征,在健康的声音中不存在.
结论:
- CPP是一个强大的语音障碍指标,可以区分病态和健康的声音,即使是带有低音的声音.
- 可以将CPP和次声调一起使用,以区分SMS与神经类型的声音.

282
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
283
Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
