[Substantiation and assessment of the effectiveness of hygienic recommendations for healthier work conditions of operators at seismic-acoustic stations].

The labour conditions of seismic operators were studied as a sample of similar professions engaged in acoustic control services. Depending on the number of the sectors under control and the seismic activity in the area, the enthropy of the sounds controlled and the information volume were assessed within 2.2-2.62 and 1.29-1.81 bit/symbol, respectively. The physiological functions' analysis in dynamics for a shift and a week revealed the peculiar features of overstrain characteristic of the working hours in a shift, particularly towards the 3rd and 6th day of the week. The recommendations proposed were designed to reduce overstrain and improve the operators' functional state at work.
