任務處理時間重疊與聲學負荷如何影響成人的聆聽努力

// How Temporal Overlap in Task Processing and Acoustic Load Affect Listening Effort in Adults

本研究探討任務間時間間隔（刺激呈現非同步性，SOA）、噪音與室內聲學對成人聆聽負荷的影響｜結果顯示短SOA會延長反應時間並提升主觀聆聽負荷，即使語音清晰度仍高｜噪音僅在長SOA時加重負荷，且輕微混響反而在安靜環境中降低聆聽負荷，顯示SOA對認知負荷的影響超越噪音。

// This study investigated how timing between tasks (stimulus onset asynchrony, SOA), noise, and room acoustics affect listening effort in adults. Using a dual-task paradigm, they found that shorter SOAs increased response times and subjective effort, even when speech clarity stayed high. Noise increased effort only at longer SOAs, while very short SOAs overwhelmed cognitive capacity, making SOA a stronger factor than noise. Mild reverberation surprisingly reduced listening effort compared to no reverberation in quiet conditions.
