Abstract:
Objective To investigate the correlation between auditory steady-state response (ASSR)and behavioral audiometry threshold in deaf children.Methods A total of 63 cases (126 ears)of severely and profoundly hearing impaired children from 0.5 years to 6 years were divided to Group A of 0.5~1.0 years,Group B of 1.1~3.0 years and Group C of 3.1~6.0 years old.ASSR and behavioral hearing tests were conducted in the sound field. 0.5~1.0 years old children were tested with the behavior observation Audiometry (BOA),1~2 years old children with visual reinforcement audiometry (VRA),while those of 3 ~6 with play audiometry (PA).Results For the ASSR response thresholds and pure tone hearing thresholds at 0.5,1,2 and 4 kHz,the correlation coefficients were 0.75,0.76,0.76,and 0.83,respectively.There was a significant correlation (P <0.01 ).The hearing thresholds were generally lower than the ASSR response thresholds,and with increasing frequency,the gaps were narrowed between the two.For Group A at each frequency the response thresholds and behavioral audiometry correlations were lower than those of Group B and C with the lowest at 0.5 kHz.Conclusion For the children of 0.5~6 years, ASSR and behavioral audiometric thresholds have good correlations.ASSR can provide information about the behav-ior thresholds for young children and those high risk children and for fitting hearing aids.
