[The prevalence of hearing impairment in transport workers and peculiarities of management of occupational loss of hearing (as exemplified by the situation in the air and railway transport)].

This article presents data on the prevalence of hearing impairment among the workers engaged in the main means of transportation(air and railway transport). They show that the relative frequency of occupational loss of hearing in the cockpit members of commercial aviation amounts to one third of all cases of analogous diseases in this country. The main professional groups of transport works suffering from hearing impairment are constituted by the representatives of the so-called elite specialities, such as flying crew personnel, locomotive engineers, and their assistants. This fact constitutes an important aspect (not only of medical but also of socio-economic significance) of the problem under consideration. The high prevalence of professional hearing impairment among the transport workers is attributable to the high noise level in the cabins of locomotives and aircraft cockpits as well as to the inadequate expert and diagnostic work or imperfection of the regulatory documentation.
