Auditory Brainstem Responses to Bone-Conducted Brief Tones in Young Children with Conductive or Sensorineural Hearing Loss

Figure 4

Left panel: ABRs to 20 dBnHL BC 500 Hz tones recorded from an infant with conductive hearing loss at the time of ABR testing, who showed normal hearing at behavioural followup. Middle panel: “Elevated” 500 Hz BC-ABR results (threshold = 30–40 dBnHL) from an infant who showed a moderate sensorineural hearing loss behaviourally. Right panel: “Elevated” 500 Hz BC-ABR results (threshold > 50 dBnHL) from an infant with a severe/profound sensorineural hearing loss bilaterally at followup. STM indicates the region of uncancelled stimulus artifact.
