Abstract: Objective To explore the correlativity between the thresholds acquired with auditory steady-state responses(ASSR) and pure tone audiometry(PTA). Methods Eighty-six subjects with normal and abnormal hearing(172 ears) were tested with ASSR and PTA at 500,1 000,2 000,4 000 Hz to get the thresholds of ASSR(single frequency) and PTA. Correlation analysis were done between the thresholds acquired with ASSR and PTA at different frequency(500,1 000,2 000,4 000 Hz) for each different hearing loss degree(≤20,21-39,40-59,60-79,≥80 dB). Results At each frequency,there was a close correlativity between the thresholds acquired with ASSR and PTA. The rectified threshold of ASSR and PTA at different frequency and hearing loss degree had been obtained. Conclusion The rectified ASSR threshold could be applied as an objective method for evaluating hearing loss to distinguish malingering deafness in the practice of forensic medicine.
