"Deaf" refers to a condition where an individual has partial or complete inability to hear sounds. This can result from various factors, including genetics, illness, or exposure to loud noises. People who are deaf may use sign language, such as American Sign Language, to communicate, or they may rely on lip-reading and other visual cues. Deafness can vary in severity, with some individuals able to hear certain sounds while others cannot hear anything at all. Many deaf individuals lead full and active lives, participating in education, work, and social activities. Awareness and understanding of deaf culture are important for fostering inclusive environments.
