Abstract
östergötland's County Council has organized an industrial hearing conservation programme, mainly aiming at small industries where knowledge and own resources presumably are small. At a subsidized cost the programme offers noise measurements, screening audiometry, information on noise control and ear protectors and a full audiological examination of certain cases. During 1971 we visited 65 companies. The results of screening audiometry (3 500 cases) and audiological examination of 212 cases are presented and discussed.
