What is the profession focused on the fitting and selling of hearing aids?

The profession focused on the fitting and selling of hearing aids is aptly described as a hearing aid specialist. This role specifically entails assessing individuals' hearing needs, recommending appropriate hearing devices, and ensuring the proper fitting and functioning of those devices. Hearing aid specialists possess specialized knowledge about various types of hearing aids and the technology behind them, as well as training in how to adjust and troubleshoot these devices to meet the unique needs of their clients.

In contrast to other professions listed, a speech therapist primarily focuses on communication issues and speech-related disorders, rather than on hearing devices. An occupational therapist works on helping individuals improve the skills needed for daily living and working, which may not involve hearing aids directly. A medical assistant, while involved in patient care and administrative tasks within a healthcare setting, does not have the specialized training or focus on hearing aids. Therefore, the hearing aid specialist is distinctly positioned as the professional responsible for the fitting and selling of hearing aids.
