まとめ
騒音の多い環境は,特に集中した聴覚では,補聴器 (HA) ユーザーの聴覚体験を悪化させます. 音響条件と聴く意図は,現実世界の音の知覚に大きな影響を与えます.
科学分野:
- 聴覚学
- 音響学
- 人とコンピュータの相互作用
背景:
- エコロジカル・モメンタリー・アセスメント (EMA) とアコースティック・データ・ロギングは,補聴器 (HA) のユーザー体験に関する洞察を提供します.
- 聴覚が正常な個体での以前の研究は,高い音圧レベル (SPL) と低い信号対ノイズ比 (SNR) を,低い聴覚評価と関連付けています.
- 傾聴の意図は生理学的反応に影響し 集中した傾聴でより高い心拍数と関連しています
研究 の 目的:
- 補聴器 (HA) の使用者の実際の聴覚体験を調査する.
- 環境音響 (SPL,SNR) と聴く意図がHAのユーザー体験に影響するかどうかを判断する.
- 心拍数,聴覚の意図,そして認識された音の環境との関係を調べる.
主な方法:
- スマートフォンベースのEMAを用いた2週間の研究には,経験豊富なHA使用者16人が参加しました.
- 参加者は,一般的な聴覚経験と,聴覚の意図 (スピーチに焦点を当てた,他者に焦点を当てた,非焦点を当てた) とともに,聴覚の意図を報告しました.
- テストHAは現地でSPLとSNRを記録し,腕帯は連続的な心拍数データを収集した.
主要な成果:
- 一般的な聴覚体験の低下は,より高いSPL,より低いSNR,およびより高い心拍数と相関しています.
- 感知される騒音の大きさは,SPLが高く,SNRが低かった.
- 集中したリスニング (スピーチまたは他のフォーカス) 中の低 SNR は,非集中したリスニングと比較して,聴覚体験と知覚された騒音を著しく悪化させた.
結論:
- 高い環境音圧レベルと騒音は,HAユーザーの現実の聴覚体験に悪影響を及ぼします.
- 集中した聴覚は,特にスピーチや他の音に対して,劣化した音響条件 (低いSNR) に特に敏感です.
- 周囲の音響と使用者の聴覚の意図は,補聴器の使用の効果と経験に影響を与える重要な要因です.

01:15Heart Sounds
2.3K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

01:30Pulse rhythm
924
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.
