Results from a hearing test are displayed on an audiogram. An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. The closer the marks are to the top of the graph, the softer the sounds that person can hear. Where the patient’s results fall on the audiogram indicate the different degrees of hearing loss. The audiogram shown below indicates the different degrees of hearing loss.

Audiogram Symbols

An “O” often is used to represent responses for the right ear and an “X” is used to represent responses for the left ear. A key on the audiogram, similar to one found on a map, identifies what the different symbols mean.

The pitches shown on the audiogram are those most important for hearing and understanding conversation. Each sound we hear when someone speaks has a different pitch and loudness. For example, the “s” sound is high in pitch and quiet. The “o” sound is low in pitch and louder.

The audiogram shown below has a shaded area that shows the range of pitch and loudness for most speech sounds.
