Noise is something we encounter everyday as well as environmental factor which affects human beings in such way that it accumulates stress with no ability to adapt. The exposure to the noise can be direct and indirect. Longer exposure to the intensive noise can have negative influence on hearing, and even cause the permanent hearing loss. Purpose of this thesis is to make overview of the recommended and upper limit of noise level in environment considering the type of sound source and reaching spot Special attention was given on upper limit values that were defined in “Regulations on highest noise levels allowed in area in which people work or inhabit“. One morning, at 11:30 a.m. traffic noise has been recorded with sound level meter. Based on the measured valued we got typical noise indicators the we have shown on spectral chart. Comparing measured results with the define values from the “Regulations on highest noise levels allowed in area in which people work or inhabit“, we can see that some measured values for noise level in open space are higher than those defined by the law. Because of it, we can conclude that values are not in accordance with the law and that we should work towards changing it. Sometimes this process is quite complicated and it demands certain money investment, but human health and suitable environment for habitation should be priority. Nature doesn't know either punishment nor reward, it just repays us the way we treat it.
