Comparison of pure tone threshold and amplitude growth function
For the evaluation and validation of AGF thresholds, a comparative analysis between the detected pure tone thresholds and the AGF results was calculated (Fig. Pure tone thresholds and AGF over a 1-year follow-up period in patients with intraoperative ECochG- and without (regular implantation). At 250 Hz, AGF results differ significantly from pure tone thresholds over the follow-up period (6 weeks:
