Analysis and modernization of the method of evaluation of occupational exposure to noise

An assessment of the negative impact of noise on the human body is given. The dependence of this effect on the intensity of noise, the duration of its action during the working day, the length of service in terms of exposure to noise, as well as the individual sensitivity of the organism, the intensity of physical activity and a complex of other harmful production factors, is considered. The analysis of the currently used methods of noise rationing, its control and evaluation at workplaces is carried out. Considered regulatory documents in the field of noise assessment in the workplace. The relationship between the maximum permissible equivalent sound levels and the severity categories of the labor process is given, as well as the dependence of the degree of risk of hearing damage on the equivalent noise level and duration of work. The paper proves the preference of using a dose assessment of noise from the point of view of taking into account the real degree of risk of hearing damage while pointing out the disadvantages inherent in this technique. In the future, it is proposed to create a measurement tool that allows evaluating both equivalent noise levels and the resulting dose of noise.
