Urban noise is a main component in the deterioration of life quality for people in urban areas. This problem mainly affects those who periodically travel through high traffic areas. The first step in reducing environmental noise is to characterize the urban setting with acoustic metrology for its diagnosis and control. This document exposes the design, construction and characterization of a wireless urban noise measurement module. The device works as a low-cost node with the capacity to be replicated for the deployment of a network of wireless acoustic sensors that allows the elaboration of dynamic urban noise maps. Each module consists of an electrical autonomy system, a single board computer and a MEMS microphone. The project also includes the design of a web portal to display measurement results in real time. The low-cost system was calibrated and compared with a class 1 sound level meter used to measure urban noise in the Autonomous City of Buenos Aires (CABA). Global differences of less than 1 dB were obtained. Urban noise was measured near the National University of Tres de Febrero following guidelines of ISO 1996-2 standard. The performance obtained in the evaluation instance and the results of the comparison were satisfactory.

In modern conditions of urban areas development, the importance of protection against noise is increasing. Measures to reduce noise levels in the city’s districts should be comprehensive and combine both organizational and architectural-construction and engineering-technological measures. To determine the most optimal combination of countermeasures, it is necessary to initially identify the sources of noise, determine their features and parameters. A complete basis for development of a set of noise reduction methods and means can be mapping of noise levels, which visually allows to determine the intensity and direction of sound spreading. One of the districts of Zhytomyr, which is isolated from other parts of the city and is characterized by a developed infrastructure and heavy traffic, was chosen for noise measurements. Measurements were performed in areas characterized by uniformity of placement, coverage of all functional areas and ability to measure the noise level both at the source of its formation and within the residential area. Based on statistical processing of the experimental data cartographic models of spatial spread of noise pollution are developed. According to the results of the research, zones with different levels of noise pollution were identified. The created map allows to choose the most optimal measures to reduce noise exposure, taking into account the characteristics of each residential area. The design noise level was determined taking into account the measures and noise map was created. The estimated efficiency of the developed measures allows to reduce the total noise level inside the district by 7–8 dB.

The Tranquility Rating coefficient (TR) is a tool proposed for assessing the quality of urban green areas, which considers both visual and acoustic aspects. This paper aims to verify how the proposed TR coefficient works for the assessment of the audiovisual quality of a typical urban space in a vicinity of an arterial road. Three different versions of the same urban space are considered: loud and visually unappealing (current state), quiet and visually unappealing (after considerable traffic reduction), and visually appealing and quiet (after redesigning). The values of noise levels required for the calculation of TR are taken from the noise maps based on the in-situ measurements, and the values of the percentage ratio of the features which are natural or man-made but contained within the visual scene (NCF) are taken from a survey conducted in the research. The results show that for the urban areas, even with very low noise levels, the TR is described as “unacceptable”. This may indicate the need for introducing an amendment for TR to be used in typical urban areas.

In Poland, the economic use of methane from coal seams has been recognized as one of the objectives of the „Energy Policy of Poland until 2030“. In Poland at the Upper Silesian Coal Basin, reconnaissance operations were initiated to collect methane from coal seams using drilling wells and hydraulic fracturing operations. During these operations, noise emission can have a significant impact on the environment. In order to limit the negative impact of noise, well pads are usually located in undeveloped areas. However, in the European Union, the majority of hard coal deposits from which methane can be extracted are located in areas with a high population density. This article presents the results of noise measurements carried out during hydraulic fracturing operations of coal seams and the results of calculations of the equivalent sound level during the daytime. Based on the analysis of noise emission, some recommendations are given regarding the location of planned new well pads in highly urbanized areas in order to meet the applicable standards of noise protection.

W Polsce ekonomiczne wykorzystanie metanu z pokładów węgla zostało uznane za jeden z celów “Polityki energetycznej Polski do 2030 roku”. W ostatnich latach powrócono do prac badawczych nad pozyskaniem metanu z pokładów węgla przy wykorzystaniu otworów wiertniczych realizowanych z powierzchni i hydraulicznego szczelinowania węgla. Takie prace prowadzone na szeroką skalę mogą mieć istotny wpływ na środowisko, a zwłaszcza na zmianę klimatu akustycznego w rejonie wiertni. Problem ten nabiera szczególnego znaczenia zwłaszcza przy realizacji prac poszukiwawczych w rejonie Górnośląskiego Zagłębia Węglowego (GZW), gdzie złoża węgla kamiennego zlokalizowane są w obszarach o wysokim stopniu zurbanizowania. W artykule przedstawiono wyniki pomiarów hałasu wykonanych podczas hydraulicznego szczelinowania pokładów węgla w rejonie GZW. Prace te były realizowane w porze dziennej przy wykorzystaniu sześciu wysokociśnieniowych pomp o mocy akustycznej 110 dB oraz jednego blendera o mocy akustycznej 105 dB. Czas trwania zabiegu hydraulicznego szczelinowania wynosił 3 h. Pomiary hałasu wykonano zgodnie z obowiązującymi przepisami prawa, przy pomocy analizatora firmy NORSONIC typ. Nor – 121 z użyciem korelacji spektralnej typu A oraz ze stałą czasową F. Wszystkie pomiary zostały wykonane na wysokości 1,5 m n.p.t., w dniach bez opadów atmosferycznych, w temperaturze otoczenia powyżej 5°C i z założoną na mikrofon osłoną przeciwwietrzną. Przed rozpoczęciem zabiegu oraz po jego zakończeniu zostały wykonane pomiary tła akustycznego. Na podstawie analizy wyników pomiarów hałasu oraz wykonanego modelowania jego rozprzestrzenienia wykonano mapy akustyczne dla rejonu wiertni.

In this study, traffic noise in Seferihisar, which is a holiday resort by the Aegean Sea in the West of Turkey, was investigated. The noise occurring in summer and winter, on weekdays, and at weekends was mapped separately. Besides, land uses exposed to traffic noise were specified. In the carried out method, the land uses were primarily mapped by using the satellite images of the study area. Then, the noise was measured at 46 points during ten days in summer and winter, on weekdays and at weekends, and it was mapped by using Inverse Distance Weighting (IDW) method and by means of Geographic Information System (GIS) techniques. The measurements were taken in the daytime (07:00-19:00), in the evening (19:00-23:00), and at night (23:00-07:00) as stated in the Turkish Regulation of Assessment and Management of Environmental Noise. Since the time interval of the daytime measurements was large, the noise was measured in three different periods for the daytime measurements. In the formation of noise maps, logarithmic averages of all measurements taken at each point were used. The noise maps were overlapped with the land use maps by the help of the GIS techniques; the land use affected by the noise was analyzed. The results showed that the road traffic noise varied from summer to winter seasons in the study area depending on heavy or light traffic. The noise occurring in summer showed an increase both on weekdays and at weekends. While the limit value was exceeded in 49 of the measurement averages taken in winter, the limit value was exceeded in 96 measurements taken in summer. The noise maps formed according to the IDW method displayed that the areas in which the limit value was exceeded in the daytime in summer took up 14.27% of the study area while this rate went down to 4.06% in winter. The study area is one of the most important destinations for summer holiday. 20.12% of the area that exceeded the limit value in summer was builtup and 10.69% of them was tourism area. The noise together with population and traffic that increase in summer season is an important environmental problem against which some precautions should be taken. The findings of the study present significant results which might guide local governments in preventing and managing the noise.

The constantly increasing intensity of transport together with the increasing sensibility of population to noise load and air pollutants force the railway route owners and operators to implement effective measures to reduce negative effects of transport on its surroundings. Although the railway traffic is more environmentally friendly than road or aircraft traffic, the modernisation of railway corridors and the increase of the passing train speed causes the increase of the noise emissions, too. This paper deals with the possibilities of abatement of the railway noise emissions directly at the source of the noise by resilient components built in the permanent way. They cause the vibration abatement of the passing trains and influence the transmission and emitation of noise emissions. With the help of the ArcGIS software with the ArcAkus module the noise propagation and the possible abbatement of noise levels after embedding of the rail absorber are simulated in a chosen area of the modernised railway track.

Wciąż postępujący wzrost natężenia ruchu transportowego w połączeniu z rosnącą wrażliwością społeczną na emisję hałasu i zanieczyszczenie powietrza skłaniają właścicieli infrastrutury i operatorów do wdrażania skutecznych środków obniżenia negatywnego oddziaływania transportu na środowisko. Mimo iż ruch kolejowy jest bardziej przyjazny środowisku niż ruch drogowy czy też lotniczy, modernizacja kolejowych korytarzy transportowych i zwiększanie prędkości przejazdu pociągów przyczyniają się również do zwiększenia poziomu hałasu. W niniejszym artykule przedstawiono możliwości zmniejszenia emisji hałasu bezpośrednio u jego źródła, poprzez zastosowanie w konstrukcji torowiska bardziej odpornych materiałów. Umożliwia to zmniejszenie wibracji pochodzących od przejeżdżającego pociągu, a co za tym idzie również redukcję poziomu emitowanego hałasu. Przy użyciu oprogramowania ArcGIS z modułem ArcAkus przeprowadzono symulację propagacji hałasu w wybranym obszarze modernizowanej sieci kolejowej oraz symulację dla tego samego obszaru, po zainstalowaniu elementów absorbujących hałas.

The Noise Directive 2002/49/EU includes obligations for noise mapping for agglomerations above 250 thousand citizens in the first step and later - above 100 thousand people. The noise map of the city consists of, at least, 4 layers of information. Each layer, in graphical form, represents different kinds of noise distribution, for traffic, railway, air and industrial noise. One can ask how to assess the complex exposure for all noises from all layers of the map? The proposition of the complex index evaluation is developed in the paper. At first, it was assumed that the basic indicator for complex description of the acoustic conditions is the sum of the weighted noise exposures connected with the LDWN level from different category of noise. The weights for the complex indicator were worked out on the basis of the results of the noise annoyance investigations, carried out by the European Working Group on health and socio-economic aspects, published in position papers (year 2002 and later). However, one can ask if the European relation between noise levels and noise annoyance is correct for Polish conditions? In the second part of the paper the results of the comparisons between EU's and Polish annoyance curves are presented. The curves were obtained as the correlation's product of the subjective assessments (query) and LDWN levels measurements and calculations. These investigations in Poland were carried out as a part of the annually project called "Noise Monitoring System" (coordinated by Chief Inspectorate of Environmental Protection). Their background results are characterized in the paper.
