摘要：Audiological use of the 40 Hz-ASSR (auditory steady state responses) could be valuable for objectively estimating the frequency-specific threshold in adults undergoing an expertise examination for medi-colegal and/or compensation purposes.The present prospective study was set up to clarify the rela-tionship between the thresholds obtained by cortical evoked response audiometry (CERA) and by 40 Hz-ASSR,in the same ears,within a large homogeneous sample of 164 subjects (328 ears) with NIHL and well documented exposure to noise.All these subjects claimed financial compensation for occupational NIHL,and there was a suspicion of exaggeration of the reported NIHLs.ASSR thresholds show a good correlation with the CERA thresholds.However,a systematic shift is noticed,ASSR thresholds being on average (1-2-3 kHz) 4.38 dB lower (i.e.showing less hearing loss) than CERA thresholds.Moreover,the binaural multiple ASSR technique allows a considerable time gain when compared to the CERA.
