概括
持续发音期间的呼吸系统变化会导致歌手喉升高和声道调整. 这些动作是个人的,在呼气过程中可能表明特定的声控点.
科学领域:
- 声学和发音声学的声学和发音声学.
- 呼吸系统生理学在语音生产中的作用
- 声动态和声道相互作用
背景情况:
- 呼吸系统,声和声道之间的相互作用对语音产生至关重要.
- 呼吸机制对声道结构的确切影响仍然不完全理解.
- 一个假设表明,减少肺体积和改变的呼气力会使喉升高,缩短声道,并促使发音补偿.
研究的目的:
- 为了研究呼吸系统变化的影响声道配置在持续的发音.
- 检查专业歌手肺体积减少,喉位置和关节调整之间的关系.
- 探索呼吸声道调节的个体变异性.
主要方法:
- 动态2D磁共振成像 (MRI) 和17名专业歌剧歌手同时进行音频录制,执行最大声调时间任务.
- 关节运动的分析,包括垂直喉位置,喉宽度和嘴唇/下巴开口.
- 提取和频谱分析音频信号后降噪.
主要成果:
- 在大多数参与者中,在语音呼气过程中观察到喉升高 (头骨运动).
- 在一些经历喉运动的受试者中,观察到关节对抗作用.
- 关节和光谱参数的适应或突发事件发生在发音时间的50%左右和之后,发音时间的初始和最后10%也出现了变化.
结论:
- 在持续的发音过程中,关节运动表现出显著的个体变化.
- 音声后半段突然发生的发音/光谱事件可能意味着一个关键调节点 (REL).
- 虽然气管拉力减少可能会导致喉升高,但呼吸调节的个体差异很大;持续和突然的关节运动是持续声调研究中的重要考虑因素.

Larynx
1.2K
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,...

Pharynx
1.3K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Suctioning the Oropharyngeal Airway
179
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...

Anatomy of Respiratory System I: Upper Respiratory Tract
1.1K
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.
Nose and nasal cavity

The Hyoid Bone
1.8K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Physical Assessment of the Respiratory Tract IV: Auscultation
275
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.
