During 1963-1990 professional disease were registered in 336 sinkers (vibration disease--42.6%; hypoacusis--35.1%; silicosis and dust-induced bronchitis--11.3 and 7.4% respectively). The mean morbidity level of professional diseases in sinkers was 12.0 per 1000 (vibration disease--4.9, hypoacusis--6.4). The level of silicosis reduced 2.9 times.

[A hygienic assessment of the noise and vibration from the machines and engines used in geological survey operations and the measures to decrease the adverse action of these factors on workers' bodies]. / Gigienicheskaia otsenka shuma i vibratsii mashin i mekhanizmov, primeniaemykh pri geologorazvedochnykh rabotakh, i mery po snizheniiu neblagopriiatnogo deistviia étikh faktorov na organizm rabochikh.

In the last 10 years, no decrease in noise and vibration conditions has been registered at a geological survey enterprise. On the contrary, the introduction of new, more productive equipment caused increase in the indices. The unfavourable labour conditions have resulted in higher occupational morbidity levels caused by the otic nerve neurites. The article sets forth a package of measures towards minimizing the hazardous influence of noise and vibration on the workers' health status.
