Main Area

Nowadays, on the territory of large cities, there is an increase in emissions of harmful substances into the atmosphere. The reasons for this are manifold: violation of design technological regimes, outdated equipment, an increase in the volume of road transport. The constantly growing intensity of traffic flows is annually accompanied by an increase in the anthropogenic load on the population of modern cities. With the increase in the number of vehicles on the streets of large cities, the world community has identified noise as one of the main factors that worsen the standard of living of people. To assess the noise pollution of the environment by road transport, a typical area of the urban area in the Kharkiv micro district was chosen. The study consisted of four main stages: Stage I – assessment of the road condition and environmental situation in the courtyards of the micro district; Stage II – assessment of acoustic pollution of the main area; Stage III – assessment of the concentration of pollutants; Stage IV – measures to reduce the level of environmental hazard. The study revealed that residential areas around Gagarin Avenue are prone to high noise levels and high concentrations of pollutants in the air. So, Gagarin Avenue is in the zone of acoustic discomfort (noise level 80 dBA), which exceeds the permissible noise level, while the degree of man-made impact on the environment during road operation is 1000 UAH / hour for every 100 people. Based on the results of calculations of the concentrations of pollutants from vehicles along Gagarin Avenue, it was found that for almost all substances their concentrations exceed the MPC by more than 3 times. Analysis of the experience of European countries in the use of noise protection screens with integrated solar panels allowed us to propose a model of noise protection barrier with integrated solar panels, which can be used to protect the urban environment from noise, sound waves and exhaust chemicals. gases from internal combustion engines. It has been established that the placement of a combined noise protection screen will reduce the noise level by about 8–15 dBA. Noise load maps were built in the main area before and after the implementation of the environmental measure. The results of the study will make it possible to introduce administrative and legislative measures to ensure regulatory noise levels for residential areas adjacent to highways and environmental safety when organizing traffic on the streets of large cities.

The COVID-19 pandemic caused lockdowns in many countries worldwide. Acousticians have made surveys to monitor how cities became quieter under the lockdown, mainly in central areas in cities. However, there have been few studies on the changes in the acoustic environment due to the pandemic in the usually quieter residential areas. It may be expected to be different from the effect in ‘originally noisy’ areas. Also, the effect could be different in Japan, because the ‘state of emergency’ declaration there was different to lockdowns elsewhere. Considering these circumstances, this article reports the results of noise monitoring and makes some observations on the acoustic environment in residential areas far from city centres, to provide an example of how the acoustic environment was affected by the state of emergency declaration due to the COVID-19 pandemic in Japan. The results showed that the reduction of noise levels was somewhat less than that reported in large cities. Also, comparing the results after the cancellation of the state of emergency, the noise level increased again. However, observations of noise sources imply that a possible change in human behaviour may have also affected the acoustic environment.

Transverse rumble strips (TRS) are commonly being installed to alert the drivers through sound and vibration effects. The sound produced affects the existing traffic noise level which caused noise annoyance to the nearby residents. This study aims to assess the traffic noise due to TRS at residential areas by determining the roadside noise levels, traffic and road characteristics and evaluating the relationship between these parameters. Middle overlapped (MO), middle layer overlapped (MLO) and raised rumbler (RR) TRS profiles with same thickness were selected. The measurements of roadside noise levels and skid resistance were conducted using sound level meter (SLM) and British pendulum tester (BPT) respectively. Traffic characteristics were evaluated using previous data measured using automatic traffic counter (ATC). In overall, MLO produced highest roadside noise levels with increase of 20.5dBA from baseline. Generally, the increase of roadside noise level due to TRS is strong with speed, weak to medium with skid resistance of TRS and no relationship with traffic volume. Based on three TRS profile types, MLO is not suitable to be installed on the roadways adjacent to the residential areas as the increase of roadside noise level is significant which is more than 5dBA compared to MO and RR.

Gas Turbine Plant

This paper deals with problems of noise control involving gas turbine plants, particularly where they are installed near residential areas already subject to noise nuisance. Noise control measures for existing industrial or power-generating plant are often designed to achieve an overall immitted noise level only marginally below the legal maximum. Considerably enhanced measures are thus required for additional plant. However, the noise from a gas turbine plant has numerous individual sources and it is shown that a differentiated approach is required. Generally, progressive reductions in noise levels involve disproportionately greater increases in expenditure on appropriate measures. Stringent environmental protection requirements necessitate cost-intensive solutions.

Reports in the past few decades indicate that Nigerian cities have high noise levels that is claimed to impact the health of residents negatively. The present article therefore examine the rela-tionshipbetween levels of environmental noise in selected residential areas in Ibadan metropolis with varying reported cases of hearing impairments (HI). Data on cases of HI were collected from one hospital; noise monitoring was conducted with the aid of a noise level meter while copies of questionnaire were administered to residents to elicit information on public perception. The distribution of reportedcases of HI among residential areas in Ibadan city showed varying magnitude (p< 0.001). About 75 % of children diagnosed with HI cases were within ages of 4-12 and female children suffered more (53.9 %). Sensorineural and conductive impairments accounted for 88.2 % of all reported HI cases.Monitored noise levels vary significantly among the selected residential area at each of morning, after-noon and evening (p < 0.05). Noise levels at morning and eveningshowed significant correlation with cases of HI reported at each of the 10 selected residential areas (r = 0.81; 0.82). Regression analysis showed that noise level explained 70.1 % of the spatial pattern of HI cases. Residents indicated that their neighbourhoods were noisy, that noise levels were on the increase and that ceremonies and generator use were major sources of noise. An integrated strategy for noise control is urgently required to stem the tide of noise pollution so as to safeguard human health in Nigerian cities.

This article assesses the acoustic pollution of Abakan, which belongs to the category of large cities. Significant excess, according to the results of research, reaching 110 dB(A), occurs pointwise along highways and is observed in the central part of the city where the railway tracks run. Excesses on these sites are recorded twice as high as the normative indicator which is equal 55 dB(A). Building sites located in the northern, western and southwestern city districts should be considered as problematic areas in terms of extra acoustic load. Within these areas, the noise load reaches 65 dB(A). In northern and southern residential areas of Abakan, the noise level corresponds to the acoustic comfort mode. Additional noise measurements made in mid- and multi-storey residential areas of the city showed that the highest noise level is observed in winter period and reaches 68,8 dB(A). In summer, the noise level does not exceed the standard adopted for this physical factor.

Noise monitoring and mapping is the critical processes to ensure that the noise level does not reach the harmful levels and provides noise exposure level details. 2-D and 3-D noise mapping has been carried out at pre-selected critical locations of major roads passing through densely populated residential areas, namely, Mathura Road, Lodhi Road, Lala Lajpat Rai Road, and Ring road, along with significant intersections, viz. Moolchand, Ashram, Sabz Burj, and Lodhi road. The monitoring has been performed during the day and night’s peak traffic hours using Sound Level Meter (SLM) Larson & Davis 831as per standard procedure. Then after, 2-D and 3-D noise maps have been prepared, visualized, and analyzed by soundPLAN (acoustic) and MapInfo Pro (Desktop GIS). The maximum noise level is observed at Ashram Chowk [81.1 dB (A)] at 8 pm; however, the minimum noise level is found to be at Lala Lajpat Rai Road [76.4dB (A)] at 7 pm. Monitoring results of noise level show non-compliance of regulatory standards for day time and night time. 2-D noise maps revealed that the noise level is maximum at the centerline of the road and decreases either side with the distance, and remains above the permissible limits at all locations. However, the 3-D noise maps show horizontal as well as vertical noise levels at all locations. The 3-D noise maps also revealed a noise level of 70 dB (A) up to a height of 6.096m at the Ashram Chowk and Moolchand intersection. However, a noise level of 65 dB (A) has been observed at the height of 5.486m at Lala Lajpat Rai Marg and Sabz Burj. This study will explore noise levels in both horizontal and vertical directions near roads surrounded by high-rise buildings. It will help the decision-makers take remedial measures.
