Objective Estimation of Frequency-Specific Pure-Tone Hearing Thresholds following Bone-Conduction Hearing Aid Stimulation

Figure 2

Individual audiograms showing pure-tone air-conduction (thick line) and bone-conduction (dotted line) audiograms measured with routine clinical audiometry. For every subject, the side with the best bone-conduction PTA threshold is shown. Arrows mark threshold exceeding the maximum output limit of the bone-conduction transducer at 6 kHz and 8 kHz. Aided behaviorally (triangles) and electrophysiologically (circles) measured pure-tone thresholds for 0.5 kHz, 1 kHz, and 2 kHz Baha stimulation were also shown using the same Baha setting for all subjects.
