ABSTRACT
Objective@#To explore the characteristics of auditory steady state evoked responses (ASSR) and auditory brainstem response (ABR) in noise-induced hearing loss population and the relationship between the response threshold of corresponding frequency and pure tone audiometry (PTA) .@*Methods@#Noise-induced hearing loss patients who completed subjective and objective audiometry in our hospital from October 2014 to October 2018 were collected. The results of PTA, ABR, ASSR and the correlation between subjective and objective audiometry were discussed.@*Results@#A total of 381 ears of 193 patients were enrolled. The difference of 0.5, 1.0, 2.0 and 4.0 kHz between ASSR threshold and PTA was 5.9, 6.9, 11.8 and 1.8 dB, respectively. The correlation coefficients were 0.638, 0.680, 0.657 and 0.608. The difference of 1.0, 2.0, 3.0 and 4.0 kHz between ABR threshold and PTA was 44.2, 35.0, 19.0 and 2.0 dB. With the increase of frequency, the threshold difference between ABRt V wave and PTA decreased gradually.@*Conclusion@#ASSR and ABR response thresholds are valuable in subjective assessment on noise-induced hearing loss. The thresholds of ASSR and ABR at 4 kHz are close to those of PTA.
