The Hearing Report Fndngs and initial recommeridations of the Board of Health Committee on Hearing \ 1984 LIBRARY DEPARTMENT OF HEAlTH!r1J" WELlJNGTON ':)" COPYRIGHT With due acknowledgment, this report may be freely copied or quoted; but no.t for a commercial .ageI1cy or for commercial purposes.· 11 FOREWORD Hearing impairment is one of the most prevalent, preventable, yet ignored disabilities. Such an invisible handicap evokes little sympathy, yet thousands of New Zealanders and their families are affected by its complex personal and social ramifications. One of the main outcomes of deafness and hearing impairment is difficulty with interpersonal communication, leading to learn ing difficulties and failure to develop skills necessary for self advocacy. Social growth. may be compromised sometimes to a severe degree. While deaf and hearing impaired people were consulted in the course of producing this report, it is essential that further working parties involve the 'consumer' much more extensively. We, the hearing, often choose to 'turn a deaf ear' to the needs of the hearing impaired. This report draws together information from a wide range of sources. In the course of gathering data on deafness and hearing impairment in New Zealand, large gaps in our knowledge became apparent. A mismatch between needs and available services was also found, despite recommendations in earlier reports such as Deafness the invisible handicap. It is hoped that the. recom mendations set out in Part 4 of the Hearing Report will be followed by multidisciplinary cooperation and action, at national, regional, and local level. The work of the committee has culminated in a result which is required reading for those with responsibilities for the wellbeing of hearing impaired people.

TERMS OF REFERENCE OF THE COMMITTEE ON HEARING To make recommendations to the Minister of Health in respect of: 1 The identification of the extent and nature of problems relating to defective hearing and ear disease'in New Zealand. 2 The measures necessary to ensure prevention, early detection and adequate management, including rehabilitation. 3 The effective coordination and expansion of services which will be required to meet present and future needs. viii PREFACE The initial tasks of the Committee on Hearing were to examine the extent and implications of hearing impairment in the community in New Zealand, and to review hearing services. Both tasks were daunting, the first because so little quantitative information on the extent of hearing impairment in New Zealand has been recorded and the second because of the difficulty of con sidering all types of hearing impairment as a single entity. A further problem that faced the committee was that of trying to quantify the often tragic effects of hearing loss on individual lives. The far-reaching consequences of hearing impairment on education, personal development, the realisation of potential and the quality of life are less apparent than the effects of most other hand icaps or health problems. In the course of their deliberations committee members have become aware of, and felt frustrated by, the limitations of statistics in conveying the implications of deafness. The lack of basic quantitative information meant that the committee had first to address itself to remedying this deficiency. In this regard the com mittee gratefully acknowledges the assistance of the Health Services Research Committee of the Medical Research Council of New Zealand which pro vided funds for a research officer to assist the committee in the tasks of gathering and reporting data on the incidence and prevalence of hearing . impairment, and describing hearing services in New Zealand. These studies, known as the Hearing Research Project, have been reported in Parts 1-3: • Part 1 presents a series of case histories to illustrate some of the effects of hearing impairment on everyday life • Part 2 brings together existing data on the incidence and prevalence of hearing loss and ear disease in New Zealand • Part 3 describes the provision of services for the hearing impaired. The Committee on Hearing has presented its recommendations in Part 4, based on information collected
