What is an audiogram?

An audiogram is fundamentally a graphical representation that displays an individual's hearing sensitivity across various frequencies, typically measured in Hertz (Hz) and represented on a chart. The x-axis of the audiogram indicates the frequency of sound, ranging from low to high pitches, while the y-axis indicates the hearing threshold, measured in decibels (dB).

The primary purpose of an audiogram is to help audiologists determine the degree and type of hearing loss a person may have, allowing for appropriate recommendations for treatment or further testing. By plotting the hearing thresholds, audiologists can visualize how well a person can hear different frequencies, making it easier to identify patterns of hearing loss, such as high-frequency or low-frequency hearing loss.

This representation is critical for diagnosing various auditory conditions and can guide clinicians in developing effective management plans for patients. Thus, the choice that accurately defines an audiogram captures its essential role in audiology.
