What this specialty covers
(1) A specialist in evaluation, habilitation and rehabilitation of those whose communication disorders center in whole or in part in hearing function. Audiologists are autonomous professionals who identify, assess, and manage disorders of the auditory, balance and other neural systems. Audiologists provide audiological (aural) rehabilitation to children and adults across the entire age span. Audiologists select, fit and dispense amplification systems such as hearing aids and related devices. (2) An audiologist is a person qualified by a master's degree in audiology, licensed by the state, where applicable, and practicing within the scope of that license. Audiologists evaluate and treat patients with impaired hearing. They plan, direct and conduct rehabilitative programs with audiotry substitutional devises (hearing aids) and other therapy.
Reading the sole-proprietor share
For this specialty, 3,410 records, or 14.4%, are flagged as sole proprietors. This self-reported NPPES field can help describe how providers are registered, but it is an imperfect proxy for private practice because it does not by itself show ownership, employment setting, independence, or whether an audiologist works in a group, hospital, school, or other organization.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- - NPI records are administrative identifiers and may not equal unique practicing audiologists.
- - Primary taxonomy reflects a classification in NPPES and may not capture every service an audiologist provides.
- Providers are counted once, by their primary taxonomy code only.
