刺激速率對嬰兒與成人由 click 與 CE‑Chirp 誘發之聽覺腦幹反應的影響

// Effect of Stimulus Rate on Click and CE-Chirp-Evoked Auditory Brainstem Responses in Infants and Adults

本研究於37個嬰兒耳與39名成人，以70 dB nHL比較點擊音與CE‑Chirp在23.3／53.3／83.3/s三速率下的ABR(腦幹聽覺反應)｜結果：I波潛時嬰成人相近，III與V波差異明顯；點擊音潛時較早、CE‑Chirp振幅較大；潛時與時頻特徵隨速率及特徵擷取法改變，臨床與研究解讀ABR應考量刺激類型與速率

// This study tested how click versus CE-Chirp stimuli and three stimulus rates (23.3, 53.3, 83.3/s) affect auditory brainstem responses (ABRs) in 37 infant ears and 39 young adults using 70 dB nHL, standard clinical measures, and automated time–frequency feature engineering. Across rates, Peak I latencies were similar in infants and adults, while Peaks III and V differed; clicks produced earlier latencies and CE-Chirps produced larger amplitudes. Absolute latencies changed with increasing rate, and ABR time–frequency features varied with rate and with the feature-extraction method. Click-rate effects matched prior literature but CE-Chirp results did not, so clinicians and researchers should account for stimulus type and rate when interpreting ABRs.
