Audiometry typically involves presenting sounds at various frequencies and volumes to determine how well an individual can hear. The test is often conducted in a soundproof room using headphones or ear inserts, and it is non-invasive, safe, and painless.

The results are plotted on an audiogram, a chart that shows the softest sound the person can hear at each frequency. The audiogram helps determine if the person has normal hearing or hearing loss, and if so, its type (sensorineural, conductive, or mixed) and severity.
