A standardized clinical audiogram that displays hearing test results, plotting hearing threshold (dB HL) against test frequency for each ear. The y-axis is inverted so that 0 dB HL (best hearing) sits at the top and increasing hearing loss extends downward, while the x-axis is logarithmic spanning the standard audiometric frequencies (125 Hz to 8 kHz). Thresholds are marked with the conventional symbols — a circle (O) for the right ear in red and a cross (X) for the left ear in blue — and connected per ear, with shaded horizontal bands indicating severity of hearing loss (normal, mild, moderate, severe, profound).
