Audiologists are hearing specialists who are trained to identify, diagnose, measure, and treat hearing disorders or balance problems. They use a variety of devices to measure hearing and the type and extent of hearing loss.

Most states require a license, and the requirements for the license vary. Typically, a doctorate or master's degree in audiology is required. Some audiologists hold a Certificate of Clinical Competence in Audiology (CCC-A), which requires additional training.
