Abstract
The available methodological approaches to assessing the noise dose characterize the multiplicity of exceeding the permissible dose, but do not reflect the transition to the weighted average equivalent level for the tasks of assessment of health risk to population living under exposure to the noise factor. Within the framework of the study, there were proposed methodical approaches which allow the transition from the multiplicity of exceedences of an individual noise dose to the calculation of the weighted average daily noise equivalent (Lden) by taking into account the number and duration of noise events. The proposed method allows the assessment and prognosis of the risks of health disorders using the approved method from the impact of noise factor (MR 2.1.10.0059-12 [9]). Testing methodological approaches using the example of children's pre-school institutions in the city of Perm made it possible to establish a daily noise dose with an assessment of the impact of each factor and determine the possible risks to health of children attending preschool institutions near transport infrastructure facilities. According to the results of this study, it was found that self-induced noise makes the main contribution to the daily noise dose.
