Some Clinical and Physiological Studies of Workers Subjected to Stable Noise,
Abstract
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.
