Change is the new normal for the U.S. hearing aid industry.
The majority of hearing aids are still sold at brick-and-mortar stores by independent hearing aid dispensers and audiologists, and by large hearing aid chains and franchises.
Hamilton County is home to nine hearing instrument specialists and 19 audiologists with active licenses, according to the Tennessee Department of Health. Neighboring counties in Tennessee have 10 audiologists and five hearing instrument specialists.
But big box retailers, Internet sales and technological advances are making inroads in the industry.
