Some of the turret lathe and automatic lathe operators studied, subjected to the influence of middle and high frequency noise at 82-99 db, showed functional changes in the nervous system characteristic for the astheno-vegetative syndrome. The degree and frequency of these changes increased with increasing noise intensity and working experience under the influence of noise. A number of persons, with no organic changes in the cardiovascular system, showed functional changes of hemodynamics, manifested as cardiac-type complaints, lability of blood pressure and a tendency toward capillary spasm. In some cases, a persistent reduction in auditory sensitivity was noted in the high frequency range, progressive with increasing noise intensity and work experience.
