Rephrase sentences or substitute words rather than repeat yourself again and again. Speak clearly and at a normal voice level. Communicate in writing, if necessary. Move away from noisy areas or the source of noise - loud air conditioning, loud music, TV and radio. Get the hearing-impaired person's attention and face in full view before talking.
Visual Impairments Be descriptive.
You may have to help orient people with visual impairments and let them know what's coming up. If they are walking, tell them if they have to step up or step down, let them know if the door is to their right or left, and warn them of possible hazards. You don't have to speak loudly to people with visual impairments. Most of them can hear just fine. Offer to read written information for a person with a visual impairment, when appropriate.
