概括
视觉反通过改善习惯性语音的声音压力水平 (SPL) 来帮助测量下压力 (SP). 虽然它增强了某些人的基本频率 (f0) 控制,但它对f0可靠性的整体影响有所不同.
科学领域:
- 语言科学
- 语音制作
- 临床测量
背景情况:
- 在评估语音障碍时,下压力 (SP) 是至关重要的,与基本频率 (f0) 和声压水平 (SPL) 相对应.
- 精确的SP测量对于可靠的语音障碍评估至关重要.
- 目前的方法可能缺乏足够的可靠性,需要改进的测量技术.
研究的目的:
- 评估f0和SPL视觉反的有效性,以提高血压下测量.
- 将习惯语音中的SP测量与语音值进行比较.
- 评估音节串与短语对SP测量可靠性的影响.
主要方法:
- 12名健康女性参与,在各种条件下测量SP:习惯性语音与语音值,音节串与短语,以及有或没有视觉f0/SPL反.
- 两个独立的评级者计算了评级者内部和评级者之间的可靠性.
- 数据分析侧重于SP测量的有效性和可靠性.
主要成果:
- 该程序为习惯性语音提供了大量有效的SP数据,但对语音值的数据较少.
- 在音节串和短语之间没有观察到SP测量的显著差异.
- 视觉反在习惯性语音中改善了SPL控制,但在语音值时显示出有限的益处;令人惊的是,10/12名参与者在没有视觉反的情况下更好地匹配目标f0.
结论:
- 视觉反显示有潜力提高血压下测量的可靠性,特别是在习惯性语音中控制SPL.
- 对基本频率控制的影响是混合的,对于偏差很大的人来说会改善,但对于偏差很小的人来说会稍微阻碍.
- 进一步的研究可能会完善这种视觉反技术,以便在不同声音任务和条件中更一致地测量SP.

01:16Measurement of Fluid Pressure
303
Fluid pressure is commonly measured using devices called manometers, which rely on liquid columns to indicate pressure differences. The height of a liquid column in a manometer reflects the pressure exerted by the fluid, providing a simple yet effective means of measurement. Different types of manometers serve specific purposes based on their configurations and the type of fluids involved.
A basic form of manometer is the piezometer, a vertical tube open at the top and filled with the same...

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
1.8K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:05Intensity and Pressure of Sound Waves
1.2K
The intensity of sound waves can be related to displacement and pressure amplitudes by using their wave expressions and the definition of intensity. The critical step to achieve this is to write the power delivered by the particles on the wave as the product of force and velocity and simplify the force per unit area as the pressure. The velocity of the medium's particles can be derived from the displacement.

01:28Physical Assessment of the Respiratory Tract IV: Auscultation
701
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.

01:28Special considerations while measuring blood pressure
822
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.

01:17Sound as Pressure Waves
2.5K
Sound waves, which are longitudinal waves, can be modeled as the displacement amplitude varying as a function of the spatial and temporal coordinates. As a column of the medium is displaced, its successive columns are also displaced. As the successive displacements differ relatively, a pressure difference with the surrounding pressure is created. The gauge pressure varies across the medium.
The pressure fluctuation depends on the difference in displacements between the successive points in the...
