Audiologists help people who have hearing, balance, and related ear problems. These problems may be a result of trauma at birth, viral infections, genetic disorders, exposure to loud noise, certain medications, or aging. Using various types of testing equipment, audiologists measure patients' ability to hear and distinguish between sounds. In addition, they use computers to evaluate and diagnose balance disorders. Audiologists analyze these test data along with educational, psychological, and other medical patient data to make a diagnosis and determine a course of treatment.
