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; a doctorate or master's degree in audiology is usually required. Some
audiologists hold a Certificate of Clinical Competence in Audiology (CCC-A),
which requires additional training.
