Abstract:
Objective To explore artifactual responses of auditory steady-state reponses (ASSRs) to bone-conduction stimuli.Methods The present study involved a group of subjects,aged between 5 to 39 months,with bilateral profound sensorineural hearing losse.Recorded were the reponses to multiple bone-conducted 0.5,1,2,4 kHz tone pips repeated at the rates of 77～101 Hz.All the subjects were sedated by Hydrate Chloride during the testing.Results Artifactual ASSRs were seen at 115 and 100.5 dB (re:1?N) (The above levels are equivalent to around 60 dB HL) at 1 and 4 kHz.No artifactual responses were recorded at 0.5 and 2 kHz stimuli at the maximum output level.Conclusion Bone-conducted hearing loss greater than moderate can not be tested reliablely due to artifactual responses and lower maximum output level than that of air conduction.
