The Cardiff Health Survey included a question asking whether the respondents had any difficulties with their hearing and, if so, to specify the biggest difficulty. This self-completed questionnaire was administered to 4,266 individuals randomly sampled from the electoral register of Cardiff in 1986. 14.7% of those responding indicated a hearing disability; and the main specific disabilities listed are described. The commonest complaints were of difficulties hearing the television and radio, and with general conversation. A number of other specific complaints were reported similar to those found in previous studies with the 'Problems Questionnaire'. Age, social class, general health, smoking and the individual's attitudes were found to influence the pattern of response.
