まとめ
声の緊張は 声の障害の一般的な症状で 音響的に評価するのは困難です このレビューでは,ストレスを定量化するのに役立つスペクトル傾きのような音響測定法が特定されていますが,正確な診断のために多式アプローチが推奨されています.
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
- 声 の 障害
背景:
- 緊張した声の質は 筋肉の緊張障害のような 機能的な声の障害の重要な特徴です
- 声の疲労と 喉頭機能の過剰に 結びついていることが多いのです
- 声の緊張の評価は,呼吸と荒さとの認識の重複と,標準化された音響の定義の欠如のために困難です.
研究 の 目的:
- 声の質のストレスの次元を定量化するために,文献で使用される音響パラメータを特定し,要約する.
- 声のストレスの音学的な相関関係に関する既存の研究をレビューする.
- より信頼性の高い音声評価ツールの開発を促す
主な方法:
- 4つの主要なデータベース (1996年−2024年) を対象に,体系的な要素を用いたスコーピングレビューが行われました.
- 311件の記録から13件の関連研究が選択されました.
- 抽出したデータには定義,知覚ツール,音響指標 (CPP,スペクトル傾きなど) および方法論が含まれていた.
主要な成果:
- 声の緊張は主に知覚の属性であり,過度の努力として説明されます.
- 一般的に報告される音響指標には,セプストラルのピーク突出度 (CPP),スペクトル傾き,低/高 (L/H) のスペクトル比,および相対基本周波数 (RFF) が含まれる.
- いくつかの音響測定は,知覚された緊張と中程度から強く相関しているが,研究の変動性は直接的な比較を妨げている.
結論:
- 緊張した声の質は複雑で 感覚と音響の両面があります
- 単一の音響メトリックでは,声の緊張を完全に捉えることはできません.スペクトルとセプストラルの特徴は,知覚の評価に有望な補足です.
- 認知,音響,生理学的データを統合したマルチモダルのアプローチは,診断の一貫性と将来の研究のために推奨されます.

Measurements of Strain
2.0K
Strain quantifies the deformation of a material under force, typically measured as normal strain, which represents the change in length when compared with the original length. Electrical strain gauges are used for enhanced accuracy. These devices consist of a conductive wire mounted on a paper backing that adheres to the material's surface. These gauges operate on the piezoresistive effect, where the wire's electrical resistance changes in response to mechanical deformation. The strain...

Assessment 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:

Perceiving Loudness, Pitch, and Location
419
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Physical 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.

Three-Dimensional Analysis of Strain
289
Three-dimensional strain analysis is crucial for understanding how materials deform under stress, particularly in elastic, homogeneous materials. This method employs principal stress axes to simplify complex stress states into more understandable forms. Subjected to stress, a small cubic element within a material either expands or contracts along these axes, transforming into a rectangular parallelepiped. This transformation effectively illustrates the material's deformation. The principal...

Strain and Elastic Modulus
4.1K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...
