// Optimal Parameters for Measuring Multiband Auditory Brainstem Responses to Continuous Speech
本研究優化了以連續有聲書語音測量特定頻率聽覺腦幹反應（ABR）的參數｜結果顯示，基頻（f0）調至90-110 Hz且具「chirp相位」的語音產生最大V波振幅｜原始f0低於170 Hz的敘述者引發最強反應，測試時間縮短至約14分鐘，提升臨床聽力評估的效率與可行性。
// This study aimed to optimize parameters for measuring frequency-specific auditory brainstem responses (ABRs) using continuous audiobook speech. By modeling and testing adults with normal hearing, the researchers found that speech with a chirp phase and a fundamental frequency (f0) lowered to 90-110 Hz produced the largest ABR wave V amplitudes. Narrators with original f0 below 170 Hz yielded the strongest responses, and optimized stimuli reduced testing time to about 14 minutes. These findings improve the efficiency and feasibility of using naturalistic speech stimuli in clinical hearing assessments.
