Figure 1 An example of an audiogram showing a Carhart notch (red arrow) in the right ear. Carhart notch as an impairment in the bone conduction threshold (BC) for 2 kHz frequency above the mean thresholds at higher and lower adjacent frequencies (green arrows). BC – bone conduction threshold; AC – air conduction threshold; Hz – hertz; dB – decibel. Prepared using CorelDraw9, Corel Corporation.
