Powszechna akceptacja i zrozumienie zasad zrównoważonego rozwoju powodują, że stosowanie urządzeń chroniących otoczenie przed hałasem komunikacyjnym wynika nie tylko z obowiązujących przepisów, ale stanowi obecnie jeden z ważnych elementów dobrej praktyki projektowania. Dlatego coraz częściej spotykamy ekrany akustyczne zarówno wzdłuż dróg, jak również przy wielu ulicach w mieście. Są to obiekty dość duże, mocno ingerujące w przestrzeń architektoniczną i zmieniające jej estetykę. Niestety, jest bardzo wiele przykładów niedoceniania ich wpływu na otoczenie i krajobraz.

Widespread acceptance and understanding of the principles of sustainable development make the use of devices that protect the environment against noise so common not only due to the existing legislation but it now is considered to be one of the important elements of good design practice. Therefore, more and more often, noise barriers are installed along roads as well as in many streets in the city. These are fairly large objects, strongly interfering with the architectural space thus changing its aesthetics. Unfortunately, there are far too many examples of ignoring their impact on both the environment and landscape.

The aim of this project was to create a ranking of the nursery schools in Wrocław with regard to the quality of the acoustic environment on their premises, using a specially developed evaluation methodology. Each nursery school was rated according to an adopted grading scale on the basis of the noise level distribution on the playground and on the nursery school building facades. Using the grading scale one can classify nursery school premises into twelve categories characterized by different acoustic environment quality, from exceptionally good (< 45 dB) to exceptionally bad (> 70 dB). The appropriately rescaled data from the acoustic map of Wrocław and the authors’ own measurements and simulation analyses were used. The developed methodology was verified by comparing the ratings yielded by it with those determined on the basis of field measurements and simulation studies, carried out for several selected nursery schools. The paper presents the results of an acoustic environment quality assessment carried out, using the developed investigative methodology, for 118 nursery schools located in Wrocław.

The 35.4-km stretch of the A8 motorway, i.e., Wrocław’s motorway ring-road (WMRR), passes through the north-west part of the city of Wrocław and 4 neighbouring districts. Analyses have shown that WMRR will be a source of noise in the environment, which may adversely affect large areas. Normative environmental protection acts mandate taking all the necessary technical and organizational measures to reduce noise generated by the operation of WMRR in order to comply with the acoustic environment quality standards. The paper presents the research methodology adopted for assessing noise impact and designing acoustic barriers, and proposed designs of acoustic barriers which take into account the acoustic requirements, technical limitations, urban development, and architectural conditions.

The influence of the road surface types on the noise emission level is a significant source of uncertainty of road noise maps drawn up using computational methods. In such methods the influence of the road surface type is taken into account through a correction to the noise emission level determined for the so-called reference surface. Depending on the kind of carriageway surface and its condition the road noise emission level may vary by several dB, which significantly affects the determined road noise propagation range. The paper presents the results of pass-by noise measurements for vehicles moving in the real city traffic. The investigations were carried out for 11 road with different pavements typical for city streets in Poland, including asphalt, asphalt concrete, stone mastic asphalt and cobblestones pavements. Also the results of comparative analyses of measurements and NMPB calculations for the investigated are be presented.
