Den lodrette akse med talangivelse fra -10 til 120 viser hørenedsættelsen i decibel hearing level (dB HL). Denne skala er udregnet således, at 0 dB svarer til den mindste lyd man kan høre med et normalt “gennemsnitsøret”. Film om audiogrammet. Se filmen nedenfor, som giver en forklaring på, hvad et audiogram er, og hvad det fortæller.
