Full textThere are two types of noise sources of ordinary geometrical forms – point and line sources, but there are many outside facilities of different and vast geometrical forms as well, whose acoustic pollution needs to be predicted and calculated conditionally in a very similar way. Work objective – to survey the impact of different forms and sizes outside facilities and of different sound capacity around industrial territory for the level of acoustic pollution. The emanation of noise sources of vast geometrical sizes has the impact (Kp) for the general sound pressure level only in close points, in comparison with the noise source measurements (3:2) The biggest impact (-3 dBA) in the distance of 5 metres has cylindrical (line type) noise source. In the bigger distances (like 40 meters) geometrical form and size of noise source has no impact and it is possible to apply acoustic capacity and noise pollution inter-connections. So, acoustic pollution level depends on the distance R and changes on 1/R² law, which is proven by experiments. In the township acoustic pollution levels exceeds dramatically (5 dBA) the allowable levels. The forthcoming inter-connection between acoustic environmental pollution and the noise source capacity around industrial subject can be used for cartography.

Full textThe main idea of this work - a comprehensive investigate dust and noise, gravel roads of rural settlements in the environment and natural greenery influence to the level of pollution. After finishing this research showed that concentrations of dust on the road with partition with a gravel surface and its atmosphere are several times higher than on the road with partition with asphalt and up to 10 m from the road exceeded the permissible 0.5 mg m-³ concentration value. The maximum delay dispersion of dust at the roadside with the lime trees. After research the amount of dust particles by size (15 m from the edge of the road where people is usually outdoor) found that the passing of single vehicle mostly recorded small (0.3 to 0.49 µm) particles - about 45,000 units. m-³. After research individual vehicle noise found that the asphalt and gravel roads in an open area of 15 m from the road sound level 6 dB above the gravel road. On gravel on the road with partition where there is no natural roadside partitions sound level 15 dB higher than the on the road with partition. At roadside vegetation in different road barricades for the noise attenuation of 10 dB difference, and the most effective noise levels of various plantation vegetation.

Full textAim of this thesis – to evaluate noise control politics implementation and used measures performance in Kaunas city during the year of 2006 – 2013 in order to ensure healthy environment without noise pollution. Main objectives: 1. To analyze the alteration of noise pollution in Kaunas city in 2006 – 2013 2. To evaluate performance of noise control politics and used measures in municipality of Kaunas city in 2006 – 2013 Work methods. This thesis is based on analysis of European Union and Lithuanian legislation acts, operational documents (strategic planning documents, complaints of the citizens, reports of national audit, etc.). Also a qualitative research method of semi structured interview was used in this thesis. The interview was based on communication (certain questionnaire) with experts who are directly working on noise politics implementation in municipality of Kaunas city. Results and conclusions. The goal of this thesis was reached by combining research of science sources what helped to structure and highlight the main problems such as low level supervision of municipality policy from national governance institutions, no strategic approach to the noise control politics in municipality of Kaunas city, ineffectively used (or even unused) donations. The interview with experts empowered to analyze the situation from the inside of the organization and it showed that noise pollution control in not a subject of priority in municipality of Kaunas city.

Full textPurpose of this workwas to research the acoustic climate in the safety zones of lightweight noise barriers from energy’s dissipation and psychological point of view. Acousticenvironment behind the noise barriers is usually described by amplitude frequency characteristic of sound fields at different distances which are caused mainly due to diffraction of sound waves. Diffraction effects are characterized by the Fresnel’s number, calculation of which includes the shape of the barrier, its dimensions, position of noise source and the listening point. Research results showed that diffraction effects were most significant up to 30 m radius from the noise barrier in its acousticshadow zone. Sound pressure level ∆L_pAat 10-15 m distance from noise barrier reduced 9…11 dBA while behind plantings ∆L_pAwas 5…8 dBA. Effect of increasing distance decreased the sound pressure level ∆L_pA6…8 dBA for noise barriers and 6…9 dBA for plantings respectively. At the non-acoustic shadow zone (50 maway from noise barrier) diffraction level was reduced by some 4…5 dBA and more noticeably from the excavation. At the distance of 10 meters from the edge of the excavation the reduction of 7 dBA in sound pressure level was found, and the decrement because of increased distance for noise barrier was 15 dBA and excavation 11 dBA respectively. It was also ascertained that acoustic environment in the shadow zones of noise barrier is not attributed to favourable. Calculated quality assessment index (QAI) was... [to full text]
