The results of several studies on hearing aid use in the Welsh population w
ere considered to investigate some general principles on determinants of su
ch use within the general populations of developed countries. Overall heari
ng aid possession and use were not found to have changed significantly over
the past 18 years, remaining at 4 per cent having obtained hearing aids an
d 3 per cent using them. The possession figures were consistent across all
methodologies used. Higher hearing aid use in the post-industrial valleys t
in which the traditional industries of coal mining and steel production had
disappeared) was explained entirely by a higher level of reported hearing
difficulties there. In all populations, less than 20 per cent of those repo
rting difficulties possessed hearing aids. Whether a hearing aid had been o
btained free of charge from the National Health Service or purchased privat
ely did not influence whether it was still used. It was concluded that an e
ffort to improve the acceptability of hearing aids and reduce their stigma
is required.
