使用短時信號校準骨傳導聽力測試設備之參考零點

// Reference zero for the calibration of bone-conduction audiometric equipment using short-duration signals

本研究針對骨導（BC）音調爆發刺激，提供了實證的等效閾值振動力水平（ETVFLs）｜採用RadioEar B81骨振器，測試27位正常成人，取得0.5、1、2、4 kHz及點擊音的中位數閾值｜結果可補充ISO 389-6標準中缺乏的BC校準數據，提升臨床骨導聽覺腦幹反應校準的準確性。

// This study provides empirical Equivalent Threshold Vibratory Force Levels (ETVFLs) for bone-conduction (BC) tonebursts, addressing the lack of BC calibration values in the ISO 389-6 (2007) standard. Using a RadioEar B81 bone vibrator and testing 27 normal adults, the research determined median thresholds for common frequencies with contralateral masking. The findings offer specific threshold values at 0.5, 1, 2, and 4 kHz and for clicks, which can inform future updates to calibration standards. These results help improve clinical accuracy for BC auditory brainstem response calibration.
