概括
半封闭的声道 (SOVT) 管在声模型中显著降低了语音值压力和流量. 管的几何形状,而不是母音类型,主要影响了这些空气动力学测量.
科学领域:
- *使用物理模型进行语音制作研究.
- * 语音的空气动力学和声学.
背景情况:
- * 物理,自我振荡的声模型 (SO-VFMs) 允许精确研究声动态.
- * 关于半遮蔽声道 (SOVT) 运动管对 SO-VFMs 与 3D 打印声道 (VTs) 结合的空气动力学测量的影响的研究有限.
研究的目的:
- * 调查SOVT管对空气动力学值测量的影响.
- * 用3D打印的VTs在SO-VFM中检查声声值压力 (PTP) 和声声值流量 (PTF).
主要方法:
- *使用了磁共振成像 (MRI) 衍生3D打印的母音/ɑ/和/u/的VTs.
- *模型与模拟人类声振动的多层SO-VFM相连.
- *测量包括在不同条件下的PTP,PTF和基本频率 (fo),包括不同尺寸的SOVT管.
主要成果:
- * SOVT管显著减少了PTP和PTF,较长和较宽的管显示了最低的值.
- *元音差异 (/u/与/ɑ/) 对PTP的影响很小,这表明影响取决于几何形状.
- *观察到PTP歇斯底里症 (发病与偏移) 和增加fo与管长.
结论:
- * SOVT管可以降低发音的空气动力学值.
- * 声道几何形状和管子尺寸是SOVT运动有效性的关键因素.
- *在SOVT练习中,空气动力学和声学相互作用是理解声功能的关键.

Suctioning the Oropharyngeal Airway
1.1K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Standing Waves in a Cavity
1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Larynx
5.2K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Anatomy of Respiratory System II: Lower Respiratory Tract
4.2K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Anatomy of Respiratory System I: Upper Respiratory Tract
5.7K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
