Journal Title: World Science - Year 2017, Vol 6, Issue 4
Abstract
The action of noise on the body is complicated and insufficiently studied. One of the indicators of the environmental significance of noise in cities, its impact on living and recreation conditions, the population's well-being is the number of complaints about noise that reaches 30% of all citizens' applications. It is established that most complaints are presented by noise of transport (75.9%), while 37.5% note that the noise is irritant, and 28% note an adverse effect on sleep. Exceeding the maximum permissible noise levels in the residential area (55 decibels in the afternoon and 45 decibels at night) by 5-10 decibels leads to an increase in complaints from the population. The disturbing and annoying effect of noise in houses is on average up to 67% with open windows and up to 43, 5% with closed windows. Noises of low intensity (up to 69 dB) differ in their effect on the human body from noises of high intensity, primarily because they exert a predominantly psychological influence. Excitation caused by even a weak noise in intensity, reaching the cerebral cortex, can create, in addition to the orientation reaction, unpleasant emotional sensations. Associative emotional reactions to small unpleasant noise arise because of what he perceives as a sign of threat or some physical and moral burden. However, it is able, like the noise of high levels, to cause an objective change in the state of the central nervous, cardiovascular and other systems. Studies of a lot of authors have made it possible to identify the organs and systems of the human body most prone to the influence of noise. The urban noise pollution it is seriously problem in the public health.
