For Community Members

Hearing Aids - Over-the-counter and prescription devices
Over-the-counter (OTC) hearing aids may be appropriate for adults with perceived mild-to-moderate hearing loss. Prescription hearing aids are recommended for more severe hearing losses and for children.
Key considerations:
- Degree of hearing loss
- Comfort and fit
- Follow-up and support
- Realistic expectations during adaptation
Noise Exposure & Prevention
Excessive noise exposure can cause permanent hearing loss.
General guidelines:
- Avoid prolonged exposure above 85 dBA
- Use hearing protection in occupational settings
- Follow safe listening practices with personal audio devices
For workplace safety guidance
For Clinicians & Trainees
Teleaudiology
Teleaudiology can expand access to hearing care in rural and underserved communities.
Implementation considerations:
- Secure video platforms
- Clear technician role delineation
- Remote troubleshooting workflows
- Patient education and follow-up structure
Community-Based Hearing Care
Expanding access requires culturally responsive, community-engaged models.
Areas of focus include:
- Task-sharing approaches
- Integration of technicians or community health workers
- Low-cost service delivery models
- Hearing care within primary and occupational health settings
