Deaf and Hard of Hearing (DHH)
Blindness separates you from objects, Sound separates you from people
- Helen Keller, who was deafblind
The problems of deafness are deeper and more complex, if not more important, than those of blindness. Deafness is a much worse misfortune. For it means the loss of the most vital stimulus - the sound of the voice that brings language, sets thoughts astir and keeps us in the intellectual company of man.
Deaf & Hard of Hearing (DHH)
The Deaf & Hard of Hearing Section of the DEEPAK: NDLI Disability Knowledge Portal presents extensive information on all aspects of the life of persons with deafness or hearing impairment. This is divided into eight subsections (detailed below). The focus has been kept on Education, Employment, and Training through first three subsections. Caregiving including support services and Institutions dealing with blindness are covered next. Assistive Technology and Android & iOS Apps have become critical assistance in all the activities. These are covered in the following two subsections. Last but not the least, the story of few Achievers, who have excelled in spite of all odds of disability and attitude of the society at large are chronicled as a documentation for achievements of human will.
While the portal is primarily designed for persons with deafness or hearing impairment in India, it does cover a lot of information in respect of science, technology, history, and practices that are agnostic to geographic and political boundary.
How do we hear?
Models of Deafness
The model through which the deaf person is viewed can impact how they are treated as well as their own self perception. There are three models of deafness rooted in either social or biological sciences. These are
Cultural Model: Deaf belong to a culture in which they are neither infirm nor disabled, but rather have their own fully grammatical and natural language.
Social Model: The social model seeks to explain difficulties experienced by deaf individuals that are due to their environment.
Medical (or Infirmity) Model: Here deafness is viewed undesirable, and it is to the advantage of the individual as well as society as a whole to "cure" this condition.
International Symbol for Deafness
