Deaf
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 with a deafness aid or 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. Medical context In a medical context, deafness is defined as a degree of hearing difficulties such that a person is unable to understand speech, even in the presence of amplification. In profound deafness, even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deaf Culture
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 Audiology, 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''. Background Members of the Deaf community tend to view Hearing loss, deafness as a difference in human experience rather than a disability or disease. Many members take pride in their Deaf identity. Deaf people, in the sense of a community or culture, can then be seen as a Minority language, linguistic mino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallaudet University
Gallaudet University ( ) is a private federally chartered university in Washington, D.C., for the education of the deaf and hard of hearing. It was founded in 1864 as a grammar school for both deaf and blind children. It was the first school for the advanced education of the deaf and hard of hearing in the world and remains the only higher education institution in which all programs and services are specifically designed to accommodate deaf and hard of hearing students. Hearing students are admitted to the graduate school and a small number are also admitted as undergraduates each year. The university was named after Thomas Hopkins Gallaudet, a notable figure in the advancement of deaf education. Gallaudet University is officially bilingual, with American Sign Language (ASL) and written English used for instruction and by the college community. Although there are no specific ASL proficiency requirements for undergraduate admission, many graduate programs require varying deg ...

Sign Language
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning, instead of spoken words. Sign languages are expressed through manual articulation in combination with #Non-manual elements, non-manual markers. Sign languages are full-fledged natural languages with their own grammar and lexicon. Sign languages are not universal and are usually not mutual intelligibility, mutually intelligible, although there are similarities among different sign languages. Linguists consider both spoken and signed communication to be types of natural language, meaning that both emerged through an abstract, protracted aging process and evolved over time without meticulous planning. This is supported by the fact that there is substantial overlap between the neural substrates of sign and spoken language processing, despite the obvious differences in modality. Sign language should not be confused with body language, a type of non verbal communicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Symbol For Deafness
Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. A common condition that results in hearing loss is chronic ear infections. Certain infections during pregnancy, such as cytomegalovirus, syphilis and rubella, may also cause hearing loss in the child. Hearing loss is diagnosed when hearing te ...

Child Of Deaf Adult
A child of deaf adult, often known by the acronym CODA, is a person who was raised by one or more deaf parents or legal guardians. Ninety percent of children born to deaf adults are not deaf, resulting in a significant and widespread community of CODAs around the world, although whether the child is hearing, deaf, or hard of hearing has no effect on the definition. The acronym KODA (kid of deaf adult) is sometimes used to refer to CODAs under the age of 18. The term was coined by Millie Brother who also founded the organization CODA, which serves as a resource and a center of community for children of deaf adults as an oral and a sign language, and bicultural, identifying with both deaf and hearing cultures. CODAs often navigate the border between the deaf and hearing worlds, serving as liaisons between their deaf parents and the hearing world in which they reside. CODA identity Many CODAs do not identify with the "hearing world" or the "deaf world". Rather, they simply identify ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochlear Implants
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments. A CI bypasses acoustic hearing by direct electrical stimulation of the auditory nerve. Through everyday listening and auditory training, cochlear implants allow both children and adults to learn to interpret those signals as speech and sound. The implant has two main components. The outside component is generally worn behind the ear, but could also be attached to clothing, for example, in young children. This component, the sound processor, contains microphones, electronics that include digital signal processor (DSP) chips, battery, and a coil that transmits a signal to the implant across the skin. The inside component, the actual implant, has a coil to receive signals, electronics, and an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Sign Language
The recorded history of sign language in Western societies starts in the 17th century, as a visual language or method of communication, although references to forms of communication using hand gestures date back as far as 5th century BC Greece. Sign language is composed of a system of conventional gestures, mimic, hand signs and finger spelling, plus the use of hand positions to represent the letters of the alphabet. Signs can also represent complete ideas or phrases, not only individual words. Most sign languages are natural languages, different in construction from oral languages used in proximity to them, and are employed mainly by deaf people in order to communicate. Many sign languages have developed independently throughout the world, and no first sign language can be identified. Both signed systems and manual alphabets have been found worldwide. Until the 19th century, most of what we know about historical sign languages is limited to the manual alphabets (fingerspelling ...

Sensorineural Hearing Loss
Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ (cochlea and associated structures), or the vestibulocochlear nerve (Cranial nerves, cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. SNHL is usually permanent and can be mild, moderate, severe, profound, or total. Various other descriptors can be used depending on the shape of the audiogram, such as high frequency, low frequency, U-shaped, notched, peaked, or flat. ''Sensory'' hearing loss often occurs as a consequence of damaged or deficient cochlear hair cells. Hair cells may be abnormal at birth or damaged during the lifetime of an individual. There are both external causes of damage, including Ear infection, infection, and Ototoxicity, ototoxic drugs, as well as intrinsic causes, including genetic mutations. A common cause or exacerbating factor in SNHL is prolonged exposure to environmental noise, or noise-induced hearing loss. Ex ...

National Technical Institute For The Deaf
The National Technical Institute for the Deaf (NTID) is the first and largest technological college in the world for students who are deaf or hard of hearing. As one of nine colleges within the Rochester Institute of Technology (RIT) in Rochester, New York, NTID provides academic programs, access, ASL in-class interpreters and support services—including on-site audiological, speech-language, and cochlear implant support. As of fall quarter 2012, NTID encompasses just under 10% of RIT's enrollment, 1259 students. Roughly 775 deaf and hard of hearing students are cross-registered into another RIT college's program with support from NTID. In addition to a master's degree in deaf education, NTID also offers a bachelor's degree program in ASL-English Interpretation. History The institute was established in 1965 by the passage of . The law also established a National Advisory Group to find a suitable site for the school. The Advisory Group considered proposals from Illinois St ...

Hearing Aids
A hearing aid is a device designed to improve hearing by making sound audible to a person with hearing loss. Hearing aids are classified as medical devices in most countries, and regulated by the respective regulations. Small audio amplifiers such as personal sound amplification products (PSAPs) or other plain sound reinforcing systems cannot be sold as "hearing aids". Early devices, such as ear trumpets or ear horns, were passive amplification cones designed to gather sound energy and direct it into the ear canal. Modern devices are computerised electroacoustic systems that transform environmental sound to make it audible, according to audiometrical and cognitive rules. Modern devices also utilize sophisticated digital signal processing, aiming to improve speech intelligibility and comfort for the user. Such signal processing includes feedback management, wide dynamic range compression, directionality, frequency lowering, and noise reduction. Modern hearing aids requ ...
