Abstract
Using pure tone audiometry, we assessed the prevalence of hearing impairment in a sample of elderly people living at home and aged 70 or more. Deafness was defined as an average loss over the speech frequencies at 1 kHz, 2 kHz and 4 kHz of 35 db or more in the better ear. We found that 60 per cent of the sample were deaf. This figure is substantially higher than previous estimates arrived at without the use of audiometry. We discuss some possible reasons for this discrepancy and consider the implications of this level of prevalence of hearing impairment for the health care of the elderly.
