The three models of deafness are rooted in either social or biological sciences. These are the cultural model, the social model, and themedicalmodel. The model through which the deaf person is viewed can impact how they are treated as well as their own self perception. In the cultural model, the Deaf belong to a culture in which they are neither infirm nor disabled, but rather have their own fully grammatical and natural language. In the medical model, deafness is viewed undesirable, and it is to the advantage of the individual as well as society as a whole to "cure" this condition. The social model seeks to explain difficulties experienced by deaf individuals that are due to their environment.
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 was among the first to discuss analogies between Deaf and hearing cultures in his appendices C and D of the 1965 Dictionary of American Sign Language.
Oralism is the education of deaf students through oral language by using lip reading, speech, and mimicking the mouth shapes and breathing patterns of speech. Oralism came into popular use in the United States around the late 1860s. In 1867, the Clarke School for the Deaf in Northampton, Massachusetts, was the first school to start teaching in this manner. Oralism and its contrast, manualism, manifest differently in deaf education and are a source of controversy for involved communities. Listening and Spoken Language, a technique for teaching deaf children that emphasizes the child's perception of auditory signals from hearing aids or cochlear implants, is how oralism continues on in the current day.
Audism as described by deaf activists is a form of discrimination directed against deaf people, which may include those diagnosed as deaf from birth, or otherwise. Tom L. Humphries coined the term in an unpublished manuscript in 1975, which he later reiterated in his doctoral project in 1977, but it did not start to catch on until Harlan Lane used it in his writing. Humphries originally applied audism to individual attitudes and practices; whereas Lane broadened the term to include oppression of deaf people.
Manually coded languages (MCLs) are a family of gestural communication methods which include gestural spelling as well as constructed languages which directly interpolate the grammar and syntax of oral languages in a gestural-visual form—that is, signed versions of oral languages. Unlike the sign languages that have evolved naturally in deaf communities, these manual codes are the conscious invention of deaf and hearing educators, and as such lack the distinct spatial structures present in native deaf sign languages. MCLs mostly follow the grammar of the oral language—or, more precisely, of the written form of the oral language that they interpolate. They have been mainly used in deaf education in an effort to "represent English on the hands" and by sign language interpreters in K-12 schools, although they have had some influence on deaf sign languages where their implementation was widespread.

In the United States, deaf culture was born in Connecticut in 1817 at the American School for the Deaf, when a deaf teacher from France, Laurent Clerc, was recruited by Thomas Gallaudet to help found the new institution. Under the guidance and instruction of Clerc in language and ways of living, deaf American students began to evolve their own strategies for communication and for living, which became the kernel for the development of American Deaf culture.
Singapore Sign Language, or SgSL, is the native sign language used by the deaf and hard of hearing in Singapore, developed over six decades since the setting up of the first school for the Deaf in 1954. Since Singapore's independence in 1965, the Singapore deaf community has had to adapt to many linguistic changes. Today, the local deaf community recognises Singapore Sign Language (SgSL) as a reflection of Singapore's diverse culture. SgSL is influenced by Shanghainese Sign Language (SSL), American Sign Language (ASL), Signing Exact English (SEE-II) and locally developed signs.
Deaf education is the education of students with any degree of hearing loss or deafness. This may involve, but does not always, individually-planned, systematically-monitored teaching methods, adaptive materials, accessible settings, and other interventions designed to help students achieve a higher level of self-sufficiency and success in the school and community than they would achieve with a typical classroom education. There are different language modalities used in educational setting where students get varied communication methods. A number of countries focus on training teachers to teach deaf students with a variety of approaches and have organizations to aid deaf students.
The history of deaf education in the United States began in the early 1800s when the Cobbs School of Virginia, an oral school, was established by William Bolling and John Braidwood, and the Connecticut Asylum for the Deaf and Dumb, a manual school, was established by Thomas Hopkins Gallaudet and Laurent Clerc. When the Cobbs School closed in 1816, the manual method, which used American Sign Language, became commonplace in deaf schools for most of the remainder of the century. In the late 1800s, schools began to use the oral method, which only allowed the use of speech, as opposed to the manual method previously in place. Students caught using sign language in oral programs were often punished. The oral method was used for many years until sign language instruction gradually began to come back into deaf education.
Language acquisition is a natural process in which infants and children develop proficiency in the first language or languages that they are exposed to. The process of language acquisition is varied among deaf children. Deaf children born to deaf parents are typically exposed to a sign language at birth and their language acquisition follows a typical developmental timeline. However, at least 90% of deaf children are born to hearing parents who use a spoken language at home. Hearing loss prevents many deaf children from hearing spoken language to the degree necessary for language acquisition. For many deaf children, language acquisition is delayed until the time that they are exposed to a sign language or until they begin using amplification devices such as hearing aids or cochlear implants. Deaf children who experience delayed language acquisition, sometimes called language deprivation, are at risk for lower language and cognitive outcomes. However, profoundly deaf children who receive cochlear implants and auditory habilitation early in life often achieve expressive and receptive language skills within the norms of their hearing peers; age at implantation is strongly and positively correlated with speech recognition ability. Early access to language through signed language or technology have both been shown to prepare children who are deaf to achieve fluency in literacy skills.
Deafness has varying definitions in cultural and medical contexts. In medical contexts, the meaning of deafness is hearing loss that precludes a person from understanding spoken language, an audiological condition. In this context it is written with a lower case d. It later came to be used in a cultural context to refer to those who primarily communicate through sign language regardless of hearing ability, often capitalized as Deaf and referred to as "big D Deaf" in speech and sign. The two definitions overlap but are not identical, as hearing loss includes cases that are not severe enough to impact spoken language comprehension, while cultural Deafness includes hearing people who use sign language, such as children of deaf adults.
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.
Language deprivation in deaf and hard-of-hearing children is a delay in language development that occurs when sufficient exposure to language, spoken or signed, is not provided in the first few years of a deaf or hard of hearing child's life, often called the critical or sensitive period. Early intervention, parental involvement, and other resources all work to prevent language deprivation. Children who experience limited access to language—spoken or signed—may not develop the necessary skills to successfully assimilate into the academic learning environment. There are various educational approaches for teaching deaf and hard of hearing individuals. Decisions about language instruction is dependent upon a number of factors including extent of hearing loss, availability of programs, and family dynamics.
Treatment depends on the specific cause if known as well as the extent, type, and configuration of the hearing loss. Most hearing loss results from age and noise, is progressive, and irreversible. There are currently no approved or recommended treatments to restore hearing; it is commonly managed through using hearing aids. A few specific types of hearing loss are amenable to surgical treatment. In other cases, treatment involves addressing underlying pathologies, but any hearing loss incurred may be permanent.
Deafness in Poland refers to the Deaf communities in Poland and education around their culture and language. Poland has a recorded history of DHH people, dating back to 1817. About 15.1% of Polish people in Poland say they have hearing loss. Polski Język Migowy is the main signed language in Poland.
South Korea's Deaf population began to come to prominence in recorded history in the late 19th century with the implementation of special education. Since then, they have gained government recognition and legal rights.
Deafness in Thailand refers to the population and culture of Deaf Hard of Hearing people in Thailand. Deafness in Thailand includes language emergence, organizations, healthcare, employment, schooling, and civil rights.
The Filipino Sign Language (FSL) is the official language of education for deaf Filipinos, which number around 121,000 as of 2000.
There is limited information on the extent of Deafness in Haiti, due mainly to the lack of census data. Haiti's poor infrastructure makes it almost impossible to obtain accurate information on many health related issues, not just the hearing impaired. In 2003, the number of deaf people in Haiti was estimated at 72,000, based on a survey provided by the World Health Organization.
