Figure 4.

Post carboplatin threshold shift and threshold shift as a function of IHC loss are shown for subject 6137. The left panel shows threshold shift as a function of frequency. The right panel shows IHC loss ranging from 78–95%. The maximum threshold shift was 35 dB at 8000 Hz. This region had ~85% IHC loss. However, lower frequencies (500–1000 Hz) had similar levels of IHC loss with much smaller threshold shifts.
