Noise Assessment

The studies were conducted in accordance with the requirements set out in the Declaration of the European Union "On Environmental Noise Assessment" and are closely related to finding solutions of the problems set out in the Law of Ukraine "On Ensuring Sanitary and Epidemic Welfare of the Population". The paper presents experimental and calculation studies on the assessment of noise pollution in the central part of Poltava. The results of such studies confirmed the hypothesis of exceeding the normative values of noise levels within some sections of the streets and directly at the intersections. It was found that the main causes of noise pollution include high intensity of public and light commercial transport means, large number of intersections and stops, poor road surface, as well as lack of acoustic protection, including lack of landscaping along roadsides. The research visually characterizes and investigates the boundaries of acoustic pollution areas distribution. Exceedence of the noise pollution normative values extends to the distance of up to 150 m from the experimental study points. The study determines the number of residents of the district who fall into high noise load areas and estimates the magnitude of risks to health of the citizens living within such areas. Experimental studies established a link between a negative impact of external noise generated by urban vehicles and urban residents' health state that requires hygienic research with application of WHO-recommended risk analysis methodology. It was found that almost 5,000 people from the study area spend most of their lives in the neighbourhoods where the noise level exceeds the permissible value of 55 dBA. Almost 2,000 of them live in the houses where penetrating noise exceeds the value of 40 dBA. Based on the results of theoretical provisions and conclusions, certain practical recommendations for management of noise pollution risks in the urban area were developed.

Acoustic pollution is a type of negative impact on the environment. According to the World Health Organization, the increased noise level is the second largest after pollution of the atmospheric air by the environmental cause of health problems in the population of industrial and transport cities. The increase in the number of road transport in the cities of the Irkutsk region leads to an increase in noise levels, its penetration into residential, public and office buildings. The increase in noise is also associated with the construction of new highways, bridges and roundabouts in cities. The article assesses noise pollution in large cities of the Irkutsk region. Observations on the composition and intensity of traffic at major intersections, highways and residential areas were carried out. With help of the sound level meter, noise level measurements were made in the daytime and at night and noise maps of the levels of the urban road network were constructed. The legislative basis for noise regulation in the Russian Federation and the countries of the European Union has been studied. A set of measures is suggested that contributes to reducing the acoustic impact on residents of the cities of the Irkutsk region.

Abstract The problem of combating urban noise is closely linked to the rational transformation of the urban environment, which must go through the elimination or reduction of the number of sources of noise, the localization of the noise emission zone, reducing the level of sound sources and protection against noise for the residential areas. Theoretical and experimental studies of acoustic loading on the territory along the highway for the typical section of the urban territory have been conducted. To estimate the complex noise impact from all sources and from individual sources, as well as to predict the total noise exposure for this site, a noise map was constructed using software. As a measure to combat traffic noise in the territory along the highway, the location of the noise protection screen was justified, taking into account the loss of part of the national income as a result of the continuous impact of noise on a person.The results of the research allow to assess the degree of technogenic impact of noise pollution during the operation of the highway, which allows regulating, by administrative and legislative methods, the nature of the impact on natural objects and human health of certain types of activities, as well as reasonably proposing measures that ensure environmental safety when organizing urban streets traffic.

The work of multilayer glass structures for central and eccentric compression and bending are considered. The substantiation of the chosen research topic is made. The description and features of laminated glass for the structures investigated, their characteristics are presented. The analysis of the results obtained when testing for compression, compression with bending, simple bending of models of columns, beams, samples of laminated glass was made. Overview of the types and nature of destruction of the models are presented, diagrams of material operation are constructed, average values of the resistance of the cross-sections of samples are obtained, the table of destructive loads is generated. The need for development of a set of rules and guidelines for the design of glass structures, including laminated glass, for bearing elements, as well as standards for testing, rules for assessing the strength, stiffness, crack resistance and methods for determining the strength of control samples is emphasized. It is established that the strength properties of glass depend on the type of applied load and vary widely, and significantly lower than the corresponding normative values of the strength of heat-strengthened glass. The effect of the connecting polymeric material and manufacturing technology of laminated glass on the strength of the structure is also shown. The experimental values of the elastic modulus are different in different directions of the cross section and in the direction perpendicular to the glass layers are two times less than along the glass layers.

Political security is very often considered through the prism of individual states. In the scholar literature in-depth analyses of this kind of security are rarely encountered in the context of international entities that these countries integrate. The purpose of this article is to draw attention to key aspects of political security in the European Union (EU) Member States. The EU as a supranational organisation, gathering Member States first, ensures the stability of the EU as a whole, and secondly, it ensures that Member States respect common values and principles. Additionally, the EU institutions focus on ensuring the proper functioning of the Eurozone (also called officially “euro area” in EU regulations). Actions that may have a negative impact on the level of the EU’s political security include the boycott of establishing new institutions conducive to the peaceful coexistence and development of states. These threats seem to have a significant impact on the situation in the EU in the face of the proposed (and not accepted by Member States not belonging to the Eurogroup) Eurozone reforms concerning, inter alia, appointment of the Minister of Economy and Finance and the creation of a new institution - the European Monetary Fund.

The article is devoted to the subject of the goals of the climate and energy policy of the European Union, which can have both a positive, and a negative impact on the environmental and energy policies. Positive aspects are the reduction of greenhouse gas emissions, diversification of energy supplies, which should improve Europe independence from energy imports, and increasing the share of renewable energy sources (RES) in the national energy system structures. On the other hand, overly ambitious targets and actions can lead to large losses for the economies of EU Member States. The article also highlights the realities prevailing in the international arena and noncompliance of international actors with global agreements on climate protection.

The author proves that the successful stability of independent Slovenia contributed to a number of factors, existing since its being incorporated in the SFRY. The factor, uniting the state has become the common goal – the aspiration to join the EU. The process of the European integration contributed to the modernization of a number of spheres, in particular social, cultural and economic ones. The global financial and economic crisis has revealed the turmoil in the economy of the state and its leadership was forced to gradually reduce a significant part of social privileges for the population. This caused the tension in the society and reduced the level of the national unity, having a negative impact on people’s wellbeing. However, since 2014, the Prime Minister M. Cherar has been trying to restore people’s trust in the state. The situation is getting better; indicators of trust in government are increasing, which also points to state capacity and political regime stability in Slovenia.

Prematurity deprives infants of the prenatal sensory stimulation essential to their correct development; in addition, the stressful environment of the NICU impacts negatively on their growth. The purpose of this review was to investigate the effects of NICU noise pollution on preterm infants and parents. We focused on the systems and projects used to control and modulate sounds, as well as on those special devices and innovative systems used to deliver maternal sounds and vibrations to this population. The results showed beneficial effects on the preterm infants in different areas such as physiological, autonomic, and neurobehavioral development. Although most of these studies highlight positive reactions, there is also a general acknowledgement of the current limits: small and heterogeneous groups, lack of structured variable measurements, systematic control groups, longitudinal studies, and normative values. The mother’s presence is always preferred, but the use of music therapy and the devices analyzed, although not able to replace her presence, aim to soften her absence through familiar and protective stimuli, which is a very powerful aid during the COVID-19 pandemic.

Market Needs

Safety monitoring provides the detection of changes in systems or operations that may suggest any case of approaching a point close to exceeding the acceptable safety standards and indicates whether corrective/prevention actions have been taken. Safety information should be maintained within the scope of transport undertakings to ensure safety and be communicated to all responsible staff, depending on each person’s function in the processes. Regulatory authorities should continuously monitor the implementation of safety management processes and the processes performed by road transport service providers. Safety management, therefore, requires investment in development and modernisation to meet market needs resulting from the mobility of residents, the growth of transport, and the obligations of countries resulting from the transport and environmental policy pursued by the European Union. Along with changes in the transport system, a need to assess their significance for the transport system’s safety arises. Depending on the transport mode (rail, air, water, road), the scope of standardised requirements is quite different each time. The paper analyses the legal requirements and acceptable practices for assessing the significance of the change in all transport modes and develops a standard method for assessing the significance of the change that meets all the requirements of electromobility safety management systems.

Indonesia and Malaysia are the largest producers and exporters of palm oil in the world vegetable oil market. Palm oil and its derivative products are the highest contributors to foreign exchange in 2018. This study aims to analyze the impact of the European Union import non-tariff trade policies on the Indonesian and Malaysian economies The analysis uses the Computable General Equilibrium (CGE) model of world trade on the Global Trade Analysis Project (GTAP) program. The results of this study found that the non-tariff import policy by the European Union had a negative impact on the economies of Indonesia and Malaysia. Moreover, the policy also has a negative impact on countries in Southeast Asia and the European Union. This shows that the enactment of non-tariff import trade policies for Indonesian and Malaysian palm oil products has a global impact.

Two Parameters

High-quality military equipment is a vital necessity for the independent state of Ukraine, especially in the conditions of aggravation of the situation at the front. One of the parameters that determines the quality of military vehicles is the level of external noise. The external noise of this type of car, in addition to the negative impact on human health (including the crew), is also an unmasking factor. In order to reduce the level of external noise of SPAI “Bogdan” on the basis of the chassis KrAZ-63221, the use of an advanced two-chamber jet muffler of the exhaust gases of the internal combustion engine is proposed. The known two-chamber jet muffler of exhaust gases has a fixed internal partition. Its acoustic efficiency is described by a known formula. It is proposed to make the inner partition of the muffler movable. This need arises from the fact of constant changes in the speed of the engine crankshaft during the movement of the car. The change in the position of the inner partition is consistent with the change in the speed of the crankshaft, because these two processes are synchronized. The mathematical package IDL was used to analyze the known formula for the efficiency of a two-chamber jet exhaust muffler of an engine with a movable inner partition. Given the need to show the dependence of the efficiency of the muffler simultaneously on two parameters – the speed of the crankshaft and the position of the movable inner partition of the muffler – the method of color coding was chosen. The design of a two-chamber jet noise muffler developed for ACS “Bogdan” is given. As a result of introduction of the developed muffler noise reduction of level of external noise of the SPAI “Bogdan” on the basis of the chassis KrAZ-63221 car on 2–3,5 dBA in the range of speeds of movement of 45–85 km/h is forecasted.
