In this article an attempt has been made to deal with the problem of deafness in all
its aspects. We have attempted to show the important causes of deafness, suggest preventive
measures and dispel some misunderstanding about the various types of deafness and the
possibility of cure by medical or surgical treatment.
T h e existing facilities for the education and training of the deaf have been briefly
surveyed. Available information about future plans has been included in the article.
An examination of the present situation seems to indicate that the value of educating
the deaf and placing them in remunerative employment is beginning to be gradually recognized.
There is an imperative need, however, for the rapid expansion of the existing facilities which
are very inadequate. T h e lack of financial resources and the trained personnel are the major
causes of retarded progress in the field.
We hope that with an increasing awareness of the value of rehabilitating the deaf,
it will be possible to generate greater interest in the public at large and in the State and
that this interest will be translated into more educational and training facilities and employ-
ment opportunities for the deaf.
Dr. C. A. Amesur, M.S. ( L o n d o n ) , is a member of National Advisory Council for the
Education of the Handicapped, India and of its Standing Committee; and of the Special
Employment Exchange for the Physically Handicapped, Bombay.
Dr. Amesur has been a member of many committees in drawing up the blue prints of
the E.N.T. and Audiology Departments of various hospitals, both at the National and local levels.
