年齡相關性聽力損失中雞尾酒會聆聽的語音感知缺陷及神經網絡變化

// Speech perception deficits and neural network alterations during cocktail-party listening in age-related hearing loss

本研究探討年齡相關聽力損失（ARHL）如何影響語音理解與腦部活動｜使用行為測試及功能性近紅外光譜（fNIRS）技術，比較ARHL患者與年輕正常聽力者｜結果顯示ARHL患者語音理解能力下降，腦部連結性與任務反應均減弱，且缺乏腦行為協同反應，反映神經適應性降低｜研究指出ARHL語音困難與神經反應異常及腦網絡彈性受損密切相關。

// This study examined how age-related hearing loss (ARHL) affects speech perception and brain activity during challenging listening tasks using behavioral tests and functional near-infrared spectroscopy (fNIRS). Participants with ARHL showed poorer speech understanding and altered brain connectivity at rest and task-related brain responses were reduced compared to younger normal-hearing individuals. Older adults with ARHL also lacked brain-behavior coupling seen in younger adults, indicating reduced neural adaptability to listening demands. The findings suggest that speech difficulties in ARHL are linked to disrupted neural responses and impaired brain network flexibility.
