Contribution to WHO programme on epidemiology of hearing impairment

South Africa

The grant was for a study of the incidence of hearing impairment in young children in South Africa, It is important to identify hearing impairment as early as possible in children if rehabilitation is to be successful.


The grant was for a feasibility study to determine the usefulness of Otoacoustic Emissions as diagnostic tools in a Universal Neonatal Screening Programme for hearing impairment.

The OE technique is a relatively simple and inexpensive technique, and so is ideally suited to large-scale screening.


This was a grant for equipment, primarily diagnostic equipment, for use in a community-based hearing programme in Thimphu.

Rehabilitation of hearing impairment in Thimphu had been severely impeded by the lack of accurate diagnostic equipment.


Grinding pepper is an important ‘cottage industry’ in Nigeria. The machines used for grinding the pepper are old and very loud, and potentially damaging to the hearing of the operators.

HCC funded a study of the level of hearing impairment in a group of 83 workers. All 83 of the grinders failed the hearing test, indicating that action is required to protect the hearing of workers in this industry.
