摘要:Objective:To define difference scores between PTA,ASSR and CERA thresholds in subjects with occu-pational NIHL.Design:44 subjects undergoing a medico-legal expert assessment for occupational NIHL and fulfilling criteria of reliability were considered.Assessment included:PTA,40 Hz binaural multiple ASSR and CERA(1-2-3 kHz).Results:The respective average difference scores (ASSR-PTA) for 1,2 and 3 kHz are 13.01 (SD 10.19) dB,12.72 (SD 8.81) dB and 10.38 (SD 8.19) dB.The average (CERA-ASSR) difference scores are 1.25 (SD 14.63)dB for 1 kHz (NS),2.73 (SD 13.03) dB for 2 kHz (NS) and 4.51 (SD 12.18) dB for 3 kHz.The correlation between PTA and ASSR (0.82) is significantly stronger than that between PTA and CERA (0.71).In a given subject,PTA thresholds are nearly always lower (i.e.,better) than ASSR thresholds,whatever the fre-quency (1-2-3 kHz) and the side (right-left).A significant negative correlation is found between the difference score (ASSR-PTA) and the degree of hearing loss.Conclusion:ASSR outperforms CERA in a medicolegal context,although overestimating the behavioral thresholds by 10-13 dB.
