Romanian legislation on the structure and content of the study to assess the impact on the environment due to mining and energy activities, forecasts and analyze the potential impact from noise and vibration generated as a result of such activities. Management of impact generated by noise and vibration on workers and residents of surrounding communities, is a key factor in the design, planning and implementation of any modern mining and also power plants because they can harm the employability of workers and residents of settlements comfort close and in situations where induce vibrations, physical integrity of potentially sensitive buildings. In this paper it is realized a classification of sound sources producing noise through mechanical action (collision and abrasion), through aerodynamic action (laminar discharge of fluid through the nozzle or those turbulent) and through thermal action, explosions or electric discharges. As the protection of own personnel with individual acoustic protection cannot be extended to the population in the nearby areas, and the control of the noise from the source is limited to the complexity of the devices, the reduction of the noise level produced by sound sources in the studied area can be realized on its way of propagation. For exemplification, we have elected Turceni steam power plant and mining quarries Jilt North and Jilt South, servicing this. Finnaly we presented experimental measurements of noise levels in terms of knowledge of the causes that produced it and the influence factors of the region. Finally we present some possible solutions for noise reduction. [ABSTRACT FROM AUTHOR]
