Since 1977, the Institute has provided rehabilitation for children with hearing impairment in Bangalore. This included auditory training after fitting with hearing aids and speech and language training. This service was given on a weekly or bi-weekly basis and children got only a few hours of therapy as they had to go to a normal school. Over the years, speech pathologists and parents realized that the children were not doing well in their respective schools. At that point of time, there were only 2 English medium schools catering to children with hearing impairment in Bangalore but none in Kannada medium. Therefore, the Institute management and staff decided to start a special school in Kannada medium for the benefit of children with hearing impairment. In 1987-88, the school began functioning in a rented building with 15 children and 2 teachers. In 1992, with a matching grant from Lions Club International Foundation, the School building came up inside the Institute campus and was named SUNAAD.
