Audiometry of 100 locomotive drivers of different age and duration of the service showed that only 32 subjects had elevated thresholds both in conventional audiogram and wide range audiogram in bone conduction. Out of the other 68 examinees 41 had hearing defects only in wide frequency range. Thus, it is possible to reveal hearing disorders early, before appearance of occupational hypoacusis and to prevent it early.
