An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. An “O” often is used to represent responses for the right ear and an “X” is used to represent responses for the left ear. There usually is a key on the audiogram; similar to one found on a map, that identifies what the different symbols mean.
The closer the marks are to the top of the graph, the softer the sounds that can be heard. The audiogram shown above on the left indicates the different degrees of hearing loss. 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 above on the right has a shaded area that shows the range of pitch and loudness for most speech sounds.
