DHH

An abbreviation for "Deaf and Hard of Hearing," encompassing the full spectrum of hearing differences from culturally Deaf individuals who use sign language as a primary language to people with varying degrees of hearing loss who may use hearing aids, cochlear implants, or rely on visual communication. In accessibility contexts, DHH is preferred as an inclusive term that acknowledges both the cultural identity of Deaf communities and the functional needs of people with hearing loss. Designing for DHH users requires attention to captions, visual alerts, sign language interpretation, and ensuring audio content has visual alternatives.
