Bone-conduction thresholds were not measurable for most of the participants; in two subjects, there were measurements in the 250–500 Hz range, but those showed no presence of ABGs. No significant differences in thresholds were found between implanted and non-implanted ears. \begin{table}

Table 1: Demographic data for the study participants with impaired hearing. rate of 21.5 Hz and at 100 dB peSPL (equivalent to 65 dB HL). WBA can be measured by sweeping the pressure similar to tympanometry and is referred to as WBT. In this study, under the WBT tab, the system automatically calculated power absorbance at ambient and peak pressure. The pressure was swept from positive (+200 daPa) to negative (-400 daPa) using a medium pump speed. The WBT measurement yielded 107 frequency data points (1/24 th octave bands), which were averaged into 16 1/3 rd octave bands to reduce inflated type I errors for the current analysis [32]. The system was calibrated daily, using the calibration software that was provided by the manufacturer (Interacoustics), and was similar to the source parameter calibration in four metal waveguide calibration units of 0.2, 0.5, 2, and 5 cc volumes provided by the manufacturer, as explained by [PERSON] et al. [33]. The cavity radius was 0.2 cm for cavities used in this study. Evanescent wave effects were minimized using the procedure recommended by [PERSON] et al. [33], and reliable transducer placement in the calibration cavities was ensured by using small diameter cavities that coupled directly to the transducer without a plastic tip (direct coupling).
