Figure 2

Illustrates shape 10- solutions of ARHI group audiogram patterns classified by k-means cluter analysis. For facilitating comparison, all audiometric shapes are calibrated at the 250 Hz frequency. ARHI cases can be divided into four subgroups: the FL shape (red line 7, 8), the 8 kHz dip (8D) shape (black line 4), the 2–4 kHz AL shape (yellow line 1, 2, 3, 9) and the mSL shape (green line 5, 6, 10).
