A multinational collaborative study on deaf children was carried out in 1977. The intention was to include all children aged 8 years with a hearing loss of 50 dB or worse, residing in the nine countries of the European Economic Community. Information was obtained on the prevalence of deafness, the distribution of mean hearing loss, aetiology and associated disabilities.
