The deaf are individuals who have significant hearing loss or are unable to hear at all. This condition can be present at birth or develop later in life due to various factors, such as illness, injury, or aging. Communication methods for the deaf often include sign language, lip reading, and written communication. Many deaf individuals are part of the Deaf community, which has its own culture and language. The most widely used sign language is American Sign Language (ASL) in the United States, while other countries have their own unique sign languages. The Deaf community values accessibility and inclusion in society.
