ABSTRACT

Objective To investigate the correlation between auditory steady state responses(ASSR)and click audiotory brainstem respone(cABR)of infants as a function of different ages below 36 months.Methods 299 infants(497 ears from 1 to 36 months)were divided into 5 groups208 ears in group 1(1~ month old),81 ears in group 2(4~ months old),47 ears in group 3(7~ months old),53 ears in group 4(13~ months old),and 108 ears in group 5(19~36 months old).The correlation analysis of the thresholds of 2 kHz and 4 kHz between ABR and ASSR were conducted,respectively with SPSS.Results In group 1,the correlation coefficient at 2 kHz between ABR and ASSR was 0.499,the correlation coefficient at 4 kHz between ABR and ASSR was 0.541,the correlation coefficient of the means of 2 kHz and 4 kHz between ABR and ASSR was 0.531.In group 2,these three correlation coefficients were 0.678,0.705 and 0.726,for group 3,0.792,0.717 and 0.777;for group 4,0.934,0.880 and 0.915,for group 5,0.817,0.810 and 0.867.Conclusion For infants of 1~18 months old,the correlation between ABR and ASSR increases as a function of ages.
