目的 探讨脑干听觉诱发电位(ABR)和40 Hz听觉诱发电位(40 Hz AERP)在职业性噪声聋诊断中的应用,为其诊断提供客观依据.方法 对54名噪声作业工人分别进行纯音测试、ABR及40HzAERP测试,对高频段及3、4 kHz处阈值与ABR反应阈值及语频段、0.5 kHz处阈值与40 Hz AERP反应阈值进行比较分析.结果 ABR反应阈值与高频段纯音听阈相关性较好；40 Hz AERP反应阈值与语频段纯音听阈比较差异较大,40 Hz AERP与语频段纯音听阈之间的校正值:轻度噪声聋组为(16.43±1.08) dBn HL,中度噪声聋组为(11.80±1.12) dBn HL.结论 在职业性噪声聋诊断中,ABR反应阈值能客观地预估纯音高频听阈,语频听阈与40 Hz AERP差异较大,不能将反应阈值误认为听阈值,而应进行反应阈值与校正值计算,得出估计的行为听阈值.

Objective To investigate the application of auditory brainstem response (ABR)and 40 Hz auditory event related potential (40 Hz AERP) to the diagnosis of occupational noise-induced hearing impairment and to provide the evidence for diagnosis of occupational deafness.Methods Pure tone audiometry,ABR and 40 Hz AERP were performed in 54 workers occupationally exposed to noise.The thresholds of higher frequency band,3 kHz and 4 kHz were compared with the threshold of ABR.The thresholds of auditory frequency ban and 0.5 kHz were compared with the threshold of 40 Hz AERP.Results A better correlation was found between thresholds of ABR and higher frequency pure tone audiometry.There was a significant difference of thresholds between 40 kHz AERP and pure tone audiometry.The correction values of thresholds between 40 kHz AERP and pure tone audiometry in the light noise-induced hearing impairment group and the moderate noise-induced hearing impairment group were (16.43±1.08) and (11.80±1.12) dBn HL,respectively.Conclusion In diagnosis of occupational noise-induced hearing impairment,the threshold of ABR can be used to estimate the hearing threshold of pure noise higher frequency.Because there is the significant difference of the thresholds between pure tone audiometry and 40 Hz AERP,the response threshold can not be served as the audiometry threshold,and the behavioral hearing thresholds can only be obtained by adjusting the response threshold with respective correction value.
