| 1 | Objective frequency-specific hearing thresholds definition for medicolegal purposes in case of occupational NIHL: ASSR outperforms CERA显示文摘Audiological use of the 40 Hz-ASSR (auditory steady state responses) could be valuable for objectivelyestimating the frequency-specific threshold in adults undergoing an expertise examination for medicolegal and/or compensation purposes. The present prospective study was set up to clarify the relationship between the thresholds obtained by cortical evoked response audiometry (CERA) and by 40 HzASSR, in the same ears, within a large homogeneous sample of 164 subjects (328 ears) with NIHL andwell documented exposure to noise. All these subjects claimed financial compensation for occupationalNIHL, and there was a suspicion of exaggeration of the reported NIHLs. ASSR thresholds show a goodcorrelation with the CERA thresholds. However, a systematic shift is noticed, ASSR thresholds being onaverage (1e2 e 3 kHz) 4.38 dB lower (i.e. showing less hearing loss) than CERA thresholds. Moreover, thebinaural multiple ASSR technique allows a considerable time gain when compared to the CERA. | P.H.DeJonckere B.Millet R.Van Gool A.Martens J.Lebacq | 2021 | Journal of Otology2021，16，4： | 2 |
