まとめ
AVQI,ABI,DSI,CPPなどの音響測定値に 大きく影響します 性別別別別の基準値は,要求の高い職業における正確な声の評価に不可欠です.
科学分野:
- 言語と聴覚科学
- アコースティック・フォネティック
- 職業的な音声科学
背景:
- 音声分析は音声機能の客観的な測定を可能にします
- 正確な評価には 性別や声の質による 声のパラメータの変動を理解することが不可欠です
- 教師は声の需要を考慮して 声の研究に適した人材です
研究 の 目的:
- 男性と女性の教師の多パラメータ音響指標 (AVQI,ABI,DSI) とセプストラル指標 (CPP,CPPS) を分析する.
- 性別と声の質がこれらの音響パラメータに及ぼす影響を調査する.
- 教師のための声の評価におけるこれらの措置の適用を調査する.
主な方法:
- 喉頭障害のない86人の教師 (48人の女性,38人の男性) の横断的観察研究.
- 持続した母音と接続されたスピーチを用いた音響評価で,Pratソフトウェアで採取された測定値.
- GRBASIスケール (Gパラメータ) と統計分析 (Mann-Whitney,tテスト) を用いた声の質の感知評価
主要な成果:
- 声の質が正常な女性教師 (G0) は,軽度な偏差を持つ女性教師 (G1) よりも高いDSIとCPPを持っていた.
- 女性はG0グループで男性より高いABIを示し,G1グループではAVQIとABIがより高い.
- G0を持つ女性では,男性と比較して,連続したスピーチにおけるCPPが有意に高かった.
結論:
- 声の質と生物学的な性別は 声学的な声のパラメータに大きく影響します
- これらの発見は,声の評価に多パラメータの音響指標を組み込むことの重要性を強調しています.
- この研究は,声の要求の高い職業における音響音声測定のための性別別基準値の必要性を支持しています.

01:21Larynx
2.1K
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,...

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
729
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:

01:29Assessment 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:

710
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.
