The current legislation of the CR does not consider as noise, inter alia, the sound from production of music operated outdoors. Production of music outdoors mainly includes concerts, discotheques; "maj?les" spring student festivals, pilgrimages, open-air markets, various celebrations, Advent concerts, music played during sporting and cultural events, etc. (also including certain daily or frequently repeated cases of such production). The enforceability of protection against such noise pollution is becoming highly ...

Wildlife crossings are structures that allow animals to cross human-made barriers safely. Wildlife overpasses are the reverse of most conventional bridges in terms of structural engineering, and this has implications for how they are designed. The Environmental Protection concerns mainly the fauna, because the development of communication and the construction of new transport routes has been increasingly fragmenting the natural environment. To fix the errors, arising from the fragmentation of the natural environme...

Heavily loaded production lines for metal surface treatment gradually lose reliability and are subject to both physical and moral ageing. For this reason their replacement by a more advanced equipment is necessary and it is the most effective action. In addition to the production process efficiency improvement, this action provides also better parameters as to the environmental protection. The modernization undertaken also meets the requirements for BAT techniques. The paper handles also potential effect of the pr...

Acoustic or phonic pollution is a type of noise pollution caused by noises, a complex of non-periodic sounds with random disagreeable insurgency that affects the psychological and biological state of human and animal organisms. The physical or objective characteristics of the noise are the strength or sound intensity (which depends on the features of the source, the distance and the possibilities of transmission or multiplication), duration and frequency. For the determination of the noise level, sound-meters, whi...

In the paper there is the analysis of the possibility of the replacement of onerous methods of surface treatment before adhesive bonding. In ecology approach adhesive bonding is not preferred techniques of joying parts. The joints are no separable, but nonetheless have wide range of usage. The adhesive bonding has many assets, like low mass of the joining elements (less material), possibility of joint of different materials, lack of rivets or screws (less weight). But typical preparatory operations in adhesive bon...

In our century and especially in recent decades the noise level reached an increasing width, becoming a polluting source of the same severity as chemical pollution. Increasing power and work speed of equipments has contributed to diversifying and increasing the number of noise sources and thus increased number of people exposed. Noise generating sources in technological procedures of processing may be of continuous nature (pneumatic energy production, water transport) or intermittent (systems for transporting mine...

The article deals with the treatment of terrain and the following forestry reclamation in the Erv?nice area situated near the city Most at the foot hills of Ore Mountains. It considers the impal of using secondary energy products for the reclamation of this previously mined area on ground water, surfac ewater, air and noise. The area had previously been used as sands and gravel waste disposal and in the last years efore there clamation there had been some natural restoration of the biotopes on the brought sands ub...
