Comparison of auditory steady-state responses and auditory brainstem responses in audiometric assessment of children with sensorineural hearing loss

Objective To investigate the differences and relationship between auditory steady-state evoked response,ASSR threshold,auditory brain stem response,ABR threshold and pure tone threshold.Methods ASSR,ABR and pure tone threshold were recorded in children with sensorineural hearing loss (hearing loss group,118ears).ASSR,ABR and pure tone threshold were compared between hearing loss group,and the relationship between ASSR,ABR and pure tone threshold were analysed.Results Both ASSR and ABR thresholds had high correlations to pure tone threshold.In the hearing loss group,the difference between ABR threshold and pure tone threshold was smaller,while that between ASSR and pure tone threshold was bigger.Correlations between ASSR and pure tone threshold were generally stronger than those between ABR and pure tone threshold.Conclusion Both ABR and the ASSR can provide reasonably accuratep redictions of behavioral threshold.
