The impact of urban traffic noise with the risk assessment to population health

The article presents results of the evaluation of urban noise levels from the road transport. Over the period 2012-2016 there was recorded an annual gain in the proportion of results of noise measurements failing to meet standards. In the daytime, evening and night time in residential areas of the city there are systematically recorded excesses of maximum permissible levels of equivalent and maximum sound levels. The highest levels of sound were recorded during the daytime: the equivalent sound level reaches 81 dBA, maximum sound level — 94 dBA. The impact of the noise of this level on the human body is characterized by a high likelihood of the development of non-specific effects (up to 0.98 units) and is evaluated as most high level. The probability (risk) for the making complaints by residents amounts up to 0.75 units (an extremely dangerous risk level), the development of hearing loss — 0.17 units (risk causing fear). High health risk indices from the impact of transport noise were established to be characteristic of cardiovascular diseases. In particular, as the age (probable duration of the exposure time) increases from 30 to 50 years, the level of risk is estimated as average (the risk ranges from 0.08 to 0.34 units), from 55 to 65 years - as high (from 0, 36 to 0.59), from 70 to 85 — as extreme (from 0.68 to 1.00). Theoretically there were substantiated measures for noise protection in the urban environment, including the architectural and planning techniques to protect the population from the traffic noise.
