An audiologist is a doctorate-level specialist in hearing anatomy. To work as a hearing aid dispenser, you must be qualified, apply for a license, and have substantial experience with hearing aids. An audiologist must have a bachelor’s degree in audiology as well as a master’s degree in audiology. Before obtaining national certification and a state license, the professional must undergo a supervised externship. An audiologist may be better suited for more medically related services including balance problems, impacted earwax, and noise-induced hearing loss.
