Hard of Hearing
Definition
Hard of hearing refers to individuals who experience partial hearing loss ranging from mild to severe. Unlike people who are completely deaf, they retain some residual hearing, which may be supported by hearing aids or other assistive devices.
Common Types of Hearing Impairment
Hearing impairment is categorized by the part of the auditory system affected.
Sensorineural Hearing Loss
Results from damage to the inner ear or auditory nerve, commonly due to aging, noise exposure, or medical conditions.
Conductive Hearing Loss
Occurs when sound is blocked in the outer or middle ear. Often caused by infections, fluid buildup, or physical obstruction.
Mixed Hearing Loss
A combination of sensorineural and conductive hearing loss, affecting both the inner and middle or outer ear.
Age-Related Hearing Loss (Presbycusis)
A gradual, bilateral hearing decline associated with aging. Typically affects high-frequency perception.
Communication Strategies
Common methods include using residual hearing with amplification (e.g., hearing aids), lip-reading, spoken language, sign language or visual communication tools, and captioning or real-time transcription in group settings.
Web Accessibility Considerations
WCAG guidelines provide a framework to make online content more accessible. Key requirements include providing captions and transcripts, ensuring good video quality for lip-reading, allowing user control over audio volume, and offering sign language interpretation when appropriate.
Legal Protections
Multiple disability laws protect the rights of people who are hard of hearing, including the ADA (U.S.), Section 508 (U.S.), AODA (Ontario, Canada), and the Equality Act 2010 (UK).
Technology and Support Tools
Assistive technology enhances access: captioning for videos and live events, hearing loop systems in public venues, real-time transcription services, and customizable audio settings in digital environments.
