audiogram

/ɔdiəˌgræm/

If you ever get your hearing tested, you might be given an audiogram, a graph of how well you hear in the frequencies tested, as a souvenir. (Or, you know, as important medical information for your records.)

Hearing specialists test people's hearing using an instrument called an audiometer, which produces an audiogram. This graph looks like a grid with X's and O's plotted on it: The X's are for the left ear; the O's are for the right ear. The x-axis of an audiogram represents frequency, how high or low a sound is. The y-axis represents intensity, or how loud a sound is. The audiogram is like a map of a person's hearing, and it is useful in detecting and treating hearing problems.
