ABSTRACT
Objective To study the characteristics of auditory brainstem responses with different forward - masking intervals in newborns with normal hearing ,and to find out the most efficient interval .Methods Auditory evoked brainstem responses were recorded from 30 newborns(60 ears) ,with forward - masking intervals of 4 ms ,8 ms ,16 ms ,32 ms ,and unmasked as control .The ABR data were statistically analyzed with SPSS 13 .0 .Results With forward - masking intervals ,all waves Ⅰ ,Ⅲ ,Ⅴ latencies and Ⅰ - Ⅴ ,Ⅰ - Ⅲ ,Ⅲ - Ⅴ interpeak latencies were significantly (P< 0 .01) prolonged compared with those of in the unmasked ,except wave Ⅲ and Ⅰ - Ⅲ interpeak latencies with 4 ms forward - masking intervals .The waves from 8 ms interval were the most prolonged .Conclusion Forward masking increases human newborn ABR latencies and interpeak latencies .The interval time influenced the effect ,and 8 ms interval is the most efficient .
