DHS Deaf, DeafBlind and Hard of Hearing State Services notes that one in five Minnesotans has a hearing loss. The Minnesota Commission of the Deaf, DeafBlind and Hard of Hearing uses the same figure. That large group includes people with very different lives and communication needs.
Deaf people who use ASL as their primary language usually need a qualified ASL interpreter, ASL video content, or a signing staff member who is fluent enough for the conversation. Hard-of-hearing people have some usable hearing. Many use hearing aids or cochlear implants, captioning, assistive listening systems or speech reading, and many do not use ASL. The NAD notes that some hard-of-hearing people describe themselves as in some ways hearing and in some ways deaf. Late-deafened people lost their hearing as adults, often after a lifetime in spoken English. They may rely heavily on real-time captioning and written communication and may be grieving the change.
DeafBlind people have combined hearing and vision loss. Their communication varies widely. Some use tactile sign language, where the person places their hands on the signer's hands. Others use close-vision signing, braille, large print, or amplification combined with magnification. The ADA lists tactile interpreters among the auxiliary aids that may be required. DeafBlind people may also need support persons for navigating spaces, and DHS State Services offers programs specifically for people with combined vision and hearing loss.
Because the range is so wide, the best starting point is a question, not a guess. How do you prefer to communicate? What works best for you in meetings, on the phone, and in writing? Is there anything that makes communication harder, such as lighting, background noise or group conversations? Then record the answer so the person does not have to repeat it at every contact. Keep in mind that preferences can differ by setting: someone may be fine with captions in a large webinar but need an interpreter for a one-on-one conversation about services. Respect the person's choice even when a different option would be easier to arrange.
