Noise Measurements

Field studies on traffic noise-induced annoyance have predominantly used estimated outside noise levels. We intended to complement existing knowledge with exposure–response relationships that are based on precise indoor noise measurements. Acoustic recordings inside the bedrooms of nightly road traffic and annoyance ratings in the following morning were obtained from 40 suburban residents (mean age 29.1 years ± 11.7; 26 females). We derived exposure–response functions for the probability to be “annoyed at least a little” (%LA). Further analyses compared data from the current study with those from two earlier studies on railway and aircraft noise. Annoyance increased with the number of traffic events and the equivalent sound pressure level. The inclusion of non-acoustical factors (such as assessment of road transport) improved the prediction considerably. When comparing the different traffic noise sources, %LA was higher for road than for air traffic at a given LAeq,night, but higher for road and railway than for air traffic at a given number of noise events. Acoustical as well as non-acoustical factors impact short-term annoyance induced by road, railway, and air traffic. Annoyance varies across noise sources, which may be due to differences in acoustical characteristics or in the temporal noise distribution throughout the night.

The Impact

The article presents results of the evaluation of urban noise levels from the road transport. Over the period 2012-2016 there was recorded an annual gain in the proportion of results of noise measurements failing to meet standards. In the daytime, evening and night time in residential areas of the city there are systematically recorded excesses of maximum permissible levels of equivalent and maximum sound levels. The highest levels of sound were recorded during the daytime: the equivalent sound level reaches 81 dBA, maximum sound level - 94 dBA. The impact of the noise of this level on the human body is characterized by a high likelihood of the development of non-specific effects (up to 0.98 units) and is evaluated as most high level. The probability (risk) for the making complaints by residents amounts up to 0.75 units (an extremely dangerous risk level), the development of hearing loss - 0.17 units (risk causing fear). High health risk indices from the impact of transport noise were established to be characteristic of cardiovascular diseases. In particular, as the age (probable duration of the exposure time) increases from 30 to 50 years, the level of risk is estimated as average (the risk ranges from 0.08 to 0.34 units), from 55 to 65 years - as high (from 0, 36 to 0.59), from 70 to 85 - as extreme (from 0.68 to 1.00). Theoretically there were substantiated measures for noise protection in the urban environment, including the architectural and planning techniques to protect the population from the traffic noise.

Level Measurement

The paper presents aspects related to noise pollution due to road traffic in Drobeta Turnu Severin. The main noise sources in Drobeta Turnu Severin are: road transport, railway and industrial activities. Based on the noise level measurement performed to assess the traffic noise over a period of 7 years, namely between 2013 and 2019, on an important road traffic artery in the mentioned city, predictions for its level over the next three years are made, correlating it with the number of cars that are supposed to cross the artery. For this study a road where the equivalent noise level exceeded the limit almost every year, was chosen. For obtaining the correlation between our data we have used the regression method. The noise level depends on the time of day in which the measurements were made but also on the season. Another correlation, between the equivalent noise level, and the number and type of cars was made, for a winter day in 2020, on another important artery, in order to see how much influence these factors have, on the noise level.

Level Monitoring

Environmental noise level monitoring in Serbia is performed in several cities and it is pursuant to the Law on Environmental Noise Protection and the accompanying regulations. Although these regulations are in accordance with the national standards, the methodology of noise monitoring varies in different cities. The issues which differ include the following: the number of measurement spots, the number of daily, weekly, and monthly measurement intervals, the duration of measurement intervals, measurement parameters and noise indicators used for noise evaluation. Different measurement procedures are the consequence of diverse city configurations, traffic structure, traffic flow, locations of noise-sensitive objects, as well as diverse contribution of noise sources. The road traffic noise level monitoring in the City of Nis has been organized from 1995 until today based on short-term measurements. The values of noise indicators are calculated based on these short-term measurements. The two newly purchased noise monitoring terminals by the Noise and Vibration Laboratory of the Faculty of Occupational Safety in Nis, enabled the long-term noise measurements. The procedure of permanent and semi-permanent road traffic noise measurements at eight locations in the City of Nis has been carried out since January 1, 2014. The results of long-term road traffic noise measurements at the main streets of Niš city are presented in this paper as well as the possibility of their presentation in the sense of the Harmonica index.

Rapid Modeling

AbstractBased on the local road traffic conditions in Beijing, China, this contribution proposes a rapid modeling method for road traffic noise sources. Since establishing the standardized experiment fields are expensive, real roads are used to determine the road traffic noise emission model in the method. Due to the similarity in the urban structures in China and Japan, this paper uses the ASJ- 2013 model as a template and replaces its model parameters with the ones output by an optimization program which minimizes the sum of absolute errors between the predicted and the measured LAeq. Real road experiments are conducted to verify the effectiveness and feasibility of the modeling method. The mean error of the model deduced by the method and the ASJ-2013 model is respectively 0.4 dB and 2.6 dB, and the mean absolute error of the two models is respectively 1.1 dB and 2.6 dB. The results of the real road experiments show that the road traffic noise sources deduced by the method are more accurate to conduct local noise prediction than those of other models.

Noise Assessment

Noise legislation in Austria does not provide an assessment of the cumulative effect of noise from different sources. The desire of citizens for a total noise assessment is getting stronger. Within the pilot project “Gesamtlärmbetrachtung” (Total Noise Investigation) Innsbruck, data from 1031 face-to-face interviews were correlated with exposure data from road, rail and air traffic noise. The interviews were selected in clusters according to the exposure combinations of these three sources. In addition to exposure-response relationships, it has also been found that the annoyance response to air and rail traffic noise is independent of the background noise from road traffic. The total noise annoyance response shows a cumulative effect in each source considered. From the source specific exposure-response relationships, a total noise assessment model based on the annoyance equivalents model was developed. This model is more suitable than the dominant source model and thus also considerable for legal application.

Noise Assessment

Motorcycle noise is an increasing noise problem, especially in Alpine valleys with winding roads and low environmental noise. The annoyance response to motorcycle engine noise is extraordinarily high in comparison to other traffic noise and cannot be explained by standard noise assessment curves. Therefore, the Tyrolean state government decided to initiate a multi-purpose study. Exposures were calculated based on sound-measurements taken across the entire district of Reutte in the western part of the State of Tyrol and a telephone survey (n = 545) was conducted with regional participants. The influence of demographic characteristics; sensitivity to noise; attitudes towards motorcycles and background noise on the annoyance was examined using bivariate analyses. In addition; exposure-response curves and their 95% confidence intervals with cut-off points of 60% and 72% for “highly annoyed” were created. The exposure annoyance response curves for motorcycle noise show a shift of more than 30 dB in annoyance reaction compared to other road traffic noise. The annoyance response to motorcycle noise in this Alpine region is concentrated on summer Sundays and Saturdays and is independent of the background exposure caused by other road traffic

Reduce Risk

Speed table is an artificial road (street) surface irregularity, which is used to reduce speed of road traffic or maintain allowed speed limit in road (street) section. These measures are used to reduce risk for pedestrians by reducing speed of passing vehicles. Before speed table, vehicles usually reduce speed, after passing it, vehicles usually increase their speed and this could increase traffic noise. Measurements were carried out during the day time in L. Asanavičiūtės Street 5, Vilnius. Measurements were divided into two parts, inside the residential apartment building and in its environment. Near the speed table recorded sound level was 69 dB, inside the residential apartment building noise level was approximately 41 dB. In this paper speed table influence on traffic noise propagation in residential area is investigated. Greičio mažinimo priemonė – dirbtinis kelio (gatvės) dangos nelygumas, skirtas transporto priemonių greičiui sumažinti arba leistinam greičiui palaikyti kelio (gatvės) ruože. Šių įrenginių paskirtis yra sumažinti pavojų pėstiesiems mažinant važiuojančių automobilių greitį. Automobiliai prieš greičio mažinimo priemonę greitį sumažina, pervažiavę ją, dažniausiai vėl didina greitį, todėl transporto keliamas triukšmas gali padidėti. Tyrimai buvo atlikti dienos metu L. Asanavičiūtės g. 5, Vilniuje. Tyrimai buvo išskirti į dvi dalis: tyrimai gyvenamojo pastato viduje ir tyrimai gyvenamojo pastato aplinkoje. Triukšmo lygis prie vertikaliosios trapecinės greičio mažinimo priemonės buvo 69 dB, tiriamojo gyvenamojo pastato viduje apie 41 dB. Šiame straipsnyje yra nagrinėjama greičio vertikaliosios trapecinės greičio mažinimo priemonės įtaka transporto keliamo triukšmo sklaidai į gyvenamąją aplinką.
