The audiogram is a graphical display of the hearing test. The two main components that are graphed are frequency and intensity. These results are displayed for each ear. When you had your hearing tested, the audiologist was determining the softest sound you could hear at each specific frequency.

Degrees of Hearing Loss

Hearing loss is classified in degrees of hearing from normal to profound. This classification is determined by the hearing threshold (or the softest a sound was heard at a specific frequency).
