Opis:
Acoustic climate in the vicinity of transportation routes is mainly affected by traffic noise. Traffic volume is decisive as regards noise emissions. Other contributing factors include road geometry and motion conditions, namely vehicle speed and the share of heavy vehicles. Every part of the road in the city has unique characteristics with respect to motion character, the route surroundings, and also every-day noise creating the so-called acoustic background. The paper presents the analysis of the results of traffic noise surveys on the example of a part of Sandomierska Street in Kielce. On a weekday, two one-hour surveys were performed, intended to measure traffic volume and to record sound levels. In the surveys, meteorological conditions were taken into account. On the basis of the data collected, the relations between the number of vehicles in motion, type of vehicles, travel direction and the noise recorded in the road were established.

Opis:
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.

Opis:
The paper shows a study on the relationship between noise measures and sound quality (SQ) features that are related to annoyance caused by the traffic noise. First, a methodology to perform analyses related to the traffic noise annoyance is described including references to parameters of the assessment of road noise sources. Next, the measurement setup, location and results are presented along with the derived sound quality features. Then, statistical analyses are performed to compare the measurement results and sound quality features. The included conclusions are focused on showing that the obtained loudness values, regardless of the used system, are similar in a statistical sense. Contrarily, sharpness, roughness and fluctuation strength values differ for the tools employed.

Opis:
The existing traffic noise prediction models in road intersections relate mainly to the typical solutions of intersection geometry and traffic organisation. There are no models for large and more complex intersections such as signalised roundabouts. This paper presents the results of studies on the development of a traffic noise prediction model for this type of intersection. The model was developed using a multiple regression method based on the results of field measurements of traffic parameters and noise levels in the vicinity of signalised roundabouts in Poland. The obtained model consists of two groups of variables affecting noise levels at the intersection. The first group determines in detail the inf luence of traffic and geometry of the closest entry. The second group shows the inf luence of more distant noise sources (traffic at the three remaining entries of the intersection) and the inf luence of the dimensions of the entire intersection. The developed model was verified through additional field measurements, as well as compared to the results of two methods of traffic noise prediction: the French ‘NMPB-Routes-2008’ and the German ‘RLS-90’. The obtained results confirmed a higher accuracy of calculations performed using the developed model in the range of: −1.2 dB ÷ +1.0 dB, while the ‘NMPB-Routes-2008’ and ‘RLS-90’ calculate precision were respectively: −2.8 dB ÷ +1.3 dB, and + 0.8 dB ÷ +5.2 dB. Therefore, the developed model allows for a more accurate prediction of noise levels in the vicinity of signalised roundabouts in a f lat terrain without buildings and noise barriers.

Opis:
Zanieczyszczenie hałasem komunikacyjnym jest jednym z najbardziej niekorzystnych oddziaływań dotykających ludzi mieszkających w miastach. Praktycznie jedna trzecia mieszkańców dużych miast w Polsce jest trwale zagrożona głównie hałasem komunikacyjnym, który może mieć negatywny wpływ na stan zdrowia. Podobny problem ma miejsce w większości miast europejskich. Problemy te doczekały się jednolitych uregulowań prawnych w UE i w Polsce. Ochrona środowiska przed hałasem w dużych miastach wynika z przepisów dotyczących konieczności sporządzania map hałasu oraz programów ochrony środowiska przed hałasem. Programy te zawierają m.in. sposoby ochrony przed hałasem komunikacyjnym do zastosowania w konkretnych miejscach. Miejsca te określane są przez wskaźnik "M", którego wartości są tym wyższe im większa jest liczba mieszkańców zamieszkujących dany teren i wartość przekroczeń wartości dopuszczalnych hałasu. W dotychczas wykonywanych programach ochrony przed hałasem przyjmowane są różnego rodzaju metody i środki ochrony przed hałasem komunikacyjnym. W wielu przypadkach metody te stanowią wyłącznie doraźne rozwiązania o niewystarczającej efektywności w miastach, jak np. ekrany akustyczne. Wyniki badań pilotażowych wskazują, że efektywnym środkiem ochrony akustycznej otoczenia ulic w obszarach zabudowy mogą być kompleksowo zastosowane fizyczne środki uspokojenia ruchu drogowego. Efektywność tych urządzeń może być wyższa niż dotychczas powszechnie stosowanych rozwiązań, przy jednoczesnym braku dodatkowego zajęcia terenu.
Exposure to traffic noise belongs to the most harmful impacts affecting people who live in towns. Nearly one third of residents of big towns in Poland suffers from permanent exposure to traffic noise, which may have adverse effects on health. The same refers to most European cities. The problems of noise is regulated by identical legislation in the EU and in Poland. Noise control in big towns arises from regulations related to obligatory provision of noise mapping and noise control plans. The plans contain, among other things, site-specific methods of protection against traffic noise. Those sites are defined by means of the “M” index, whose value is the higher the more people live in the area and the more permissible noise levels are exceeded. The noise control plans prepared to-date contain a range of methods and measures aimed at ensuring protection against traffic noise. In many cases those methods are nothing but improvised response and are not effective enough in towns, for example noise barriers. Results of pilot research indicates that comprehensive physical traffic calming measures may prove to be an effective and long lasting noise control solution in the surrounding of streets in urban areas. Physical traffic calming may be more effective than the measures commonly used so far which does not require additional land acquisition.

Opis:
The use of periodic structures as noise abatement devices has already been the object of considerable research seeking to understand its efficiency and see to what extent they can provide a functional solu- tion in mitigating noise from different sources. The specific case of sonic crystals consisting of different materials has received special attention in studying the influence of different variables on its acoustic performance. The present work seeks to contribute to a better understanding of the behavior of these structures by implementing an approach based on the numerical method of fundamental solutions (MFS) to model the acoustic behavior of two-dimensional sonic crystals. The MFS formulation proposed here is used to evaluate the performance of crystals composed of circular elements, studying the effect of varying dimen- sions and spacing of the crystal elements as well as their acoustic absorption in the sound attenuation provided by the global structure, in what concerns typical traffic noise sources, and establishing some broad indications for the use of those structures.

Opis:
In the paper, the PROP10 program is used to present the time-average sound level on façades of buildings in the vicinity of a crossroads. The propagation model within an urban system forming canyon streets includes the wave interaction with obstacles, multi-reflections from building walls and single and double diffraction at their wedges. For the current purpose the program is provided with a road model in which the vehicle route is divided into sub-segments with lengths and linear densities of emitted energy that depend on the traffic organization in the vicinity of the crossroads. The lengths of the sub-segments, where vehicles wait and are forced to a subsequent start and stop, depend on the flow rates on lanes, the equivalent vehicle length, the red and green light times and the speed of leaving a crossroads. The linear energy density at these sub-segments depends on a parameter characterizing the energy emitted during the starting of a vehicle. The time-average sound level is analyzed as a function of the enumerated parameters.

Opis:
Noise Monitoring Networks (NMNs) have been implemented in many cities by town councils, allowing them to know, in real time, the environmental noise levels in the busiest streets by the continuous measurement of selected acoustic parameters throughout the year. NMNs are aimed at: 1) detecting areas of the city that breach guidelines for acoustic quality objectives; 2) obtaining noise data needed to develop and implement action plans; and 3) informing the public about the permissible acoustic pollution for different districts and times of day. The aim of this work was to analyse data from the NMN of the city of Huelva (Spain), in order to study the influence on the noise of re-asphalting the busiest streets. The street pavements improve LAeq, 24 h from 3 up to 8 dB(A), depending on the type of the route. These results could be used by council authorities in deciding when to undertake the re-asphalting of the streets of Huelva, and to select the type of asphalt that should be used.
