Abstract:
Objective To explore the relationship between the duration of tone pip with Blackman envelop and morphology or latency of auditory brainstem responses.Methods ABRs were recorded using 0.5,1,2,4 and 8 kHz tone pips with Blackman envelope at different intervals.Results The longer the duration of stimulus was,the better the frequency specificity of stimulus was.However,the ABR morphology were affected and the latencies of wave Ⅲ were prolonged.Conclusion When using tone pips to evokes ABR,stimuli should be well considered in order to produce better frequency specificity and transient state.
