Doctors of Auidology are professionals whose scope of practice is defined as the diagnosis and treatment of hearing losss. The training includes extensive theoretical and and practical training in the diagnosis of hearing loss, and the selection, fitting and verification of hearing aids.  Currently a national accrediation process ensures the quality of the programs and the thoroughness of the training.  Requiring a Doctor of Audiology to  go through another examination to fit hearing aids is highly redundant and creates a lot of unnecessary processes.
