A person who cannot see or hear is commonly referred to as deaf-blind. Deaf-blind individuals may have varying degrees of vision and hearing loss, and often rely on other senses, sign language, and tactile communication to navigate the world around them. Support services and tools such as tactile signing, braille, and assistive technology are essential for their communication and daily living.

A person who cannot hear or speak is commonly referred to as "deaf-mute" in older terminology. However, the preferred term today is "deaf and nonverbal" or "deaf and mute" depending on whether the person communicates primarily through sign language or other means.
