Deaf culture is the set of social beliefs, behaviors, art, literary traditions, history, values, and shared institutions of communities that are influenced by deafness and which use sign languages as the main means of communication. When used as a cultural label especially within the culture, the word deaf is often written with a capital D and referred to as "big D Deaf" in speech and sign. When used as a label for the audiological condition, it is written with a lower case d. Carl G. Croneberg coined the term of "Deaf Culture" and he was the first to discuss analogies between Deaf and hearing cultures in his appendices C/D of the 1965 Dictionary of American Sign Language.

The term BANZSL was coined by Trevor Johnston and Adam Schembri.

The Deaf rights movement encompasses a series of social movements within the disability rights and cultural diversity movements that encourages deaf and hard of hearing to push society to adopt a position of equal respect for them. Acknowledging that those who were Deaf or hard of hearing had rights to obtain the same things as those hearing lead this movement. Establishing an educational system to teach those with Deafness was one of the first accomplishments of this movement. Sign language, as well as cochlear implants, has also had an extensive impact on the Deaf community. These have all been aspects that have paved the way for those with Deafness, which began with the Deaf Rights movement.

Deafblindness is the condition of little or no useful hearing and little or no useful sight. There are different degrees of vision loss and auditory loss within each individual, thus making the deafblind community unique with many types of deafblindness involved. Because of this diversity, each deafblind individual's needs regarding lifestyle, communication, education, and work need to be addressed based on their degree of dual-modality deprivation in order to improve their ability to live independently. In 1994, it was estimated that roughly 35,000–40,000 United States residents are medically deafblind. Helen Keller was a well-known example of a deafblind individual.

Fingerspelling is the representation of the letters of a writing system, and sometimes numeral systems, using only the hands. These manual alphabets, have often been used in deaf education, and have subsequently been adopted as a distinct part of a number of sign languages; there are about forty manual alphabets around the world. Historically, manual alphabets have had a number of additional applications—including use as ciphers, as mnemonics, and in silent religious settings.
