Noise pollution of the urban environment in recent years has become a serious environmental and social problem, a threat to the health and well-being of the population. Although noise for the population is not such a priority, as, for example, chemical pollution of air and water, but it has always been the subject of public interest. There are varieties of noise generation sources of which the traffic noise could be a major source. Among the many factors affecting the health of the population, urban noise is the most common and aggressive. The article deals with the problem of the negative impact of noise on human health and on the structure of the general morbidity of the population. The authors addressed the problem of noise pollution in the city of Kaluga. Presents the dynamics of changes in the number of cars and noise pollution over the past ten years. It is shown that today cars are the dominant sources of urban noise environment. The interpretation of the results of full-scale acoustic measurements carried out on the main urban highways is given. The regularities of changes in noise levels in different seasons of the year are revealed. It is concluded that the permissible values of acoustic effects in the city of Kaluga are exceeded. The results of the integrated assessment of child morbidity associated with an increase in the number of vehicles in the city and an increase in acoustic load are presented.

This paper presents the results obtained in a study on environmental noise pollution in the city of Curitiba, Brazil. The equivalent sound level values - LA,eq,2hr - were measured and tabulated for 1000 locations spread over the urban zones of the city of Curitiba. It was found that 93.3% out of the locations display, during the day, equivalent sound levels over 65 dB(A), and 40.3% out of the locations measured display during the day extremely high values of equivalent sound levels: over 75 dB(A). Measurement points were evaluated according to the assumptions established by two types of legislation: 1) local legislation: Law 8583 of 1995, which deals with urban noise and public comfort; 2) international legislation: the criteria of the US Department of Housing and Urban Development - HUD.

The pandemic of coronavirus disease (COVID-19) led to the need for drastic control measures around the world to reduce the impact on the health of the population. The confinement of people in their homes resulted in a significant reduction in human activity at every level (economic, social, industrial, etc.), which was reflected in a decrease in environmental pollution levels. Studying the evolution of parameters, such as the level of environmental noise caused by vehicle traffic in urban environments, makes it possible to assess the impact of this type of measure. This paper presents a case study of the acoustic situation in Cáceres (Spain) during the restriction period by means of long-term acoustic measurements at various points of the city.

Noise pollution in urban areas is recognized as a major environmental concern in India. The lack of infrastructure and fast paced life in major metropolitan cities of India has made the urban environment extremely crowded, busy as well as noisy and as a result the millions of people living in the major metropolitan areas are suffering from the impacts of noise pollution. Noise levels are escalating at such a rate that it has become a major threat to the quality of human lives. Direct links between noise and health have been established by research conducted over the past few decades. There are several causes for urban degradation such as population migration, environmental considerations not adequately being incorporated into master plans, uncoordinated and haphazard development, weak implementation of plans and laws and inadequate institutional competences and resource crunch. This paper discusses the causal factors, impacts and the different approaches adopted by the Central Government as well as some major State Pollution Control Boards to curb the urban noise problem and the need for looking into non-conventional solutions such as Ecocity programme to bring in visible environmental improvement.

This work is focused on the diagnosis of behavior, from the point of view of control emissions and noise level, of a power Turbogas plant during the process of commissioning, to guarantee that its operation complies with national and international standards. The environmental diagnosis of the power plant was developed as part of the performance evaluation of the unit. The conditions of the unit evaluation include operation at base load and partial load, as well as time periods for load changes. The evaluated power plant consists of an aeroderivative gas turbine installed in a simple cycle, operating with a cooling system (chiller) installed in the urban zone of Mexico City. Therefore, it should comply with the legislation and regulations of the city concerning air pollution and allowed noise, besides the international standards established by the manufacturer. The study includes emissions measurements using a Continuous Emissions Monitoring System installed in-situ, previously calibrated and checked during and after the test which was found inside the permissible deviation of 3%. Measurements were recorded at intervals of 5 minutes during test periods of 110 minutes for each load and 45 minutes for load changes. On the other hand, noise pressure evaluation was carried out in near field as well as far field produced by the power plant during operation. Measurements were carried out by using precision instruments installed specifically for it. A temporary system for obtaining data was used to monitoring the environmental conditions every 30 seconds. It was possible to verify that the turbogenerator complies with all noise levels and contaminant emissions requirements and regulations according to the limits established by the manufacturer and national and international standards.

ResumenEsta investigación aporta bases científicas y metodológicas de diagnóstico territorial, relacionadas al efecto causal de las autopistas elevadas sobre su entorno inmediato. Para lograrlo se utilizan antecedentes históricos y normativos, pero también, el procesamiento de datos abiertos y la utilización de herramientas econométricas que dimensionan impacto. Los resultados identifican 11.893 hogares afectados por contaminación sonora, reducción en la edificabilidad, reducción en el valor de las propiedades y aumento en la probabilidad de robo o hurto. La Ciudad de Buenos Aires es la principal centralidad de la región en términos de empleo, producción y servicios del país. Esta condición sustenta la utilidad de las autopistas en términos económicos y de movilidad; sin embargo, enfrenta desafíos de impacto ambiental y calidad de vida, que deben ser priorizados en el marco de la agenda de cambio climático y vulnerabilidad de las poblaciones. En el documento se analiza además la evolución del modelo de ciudad con autopistas, sus transformaciones y las posibilidades futuras de estas infraestructuras en los entornos urbanos. Optimizarlas, reemplazarlas por túneles o derribarlas, son las principales acciones que las ciudades vienen desarrollando, específicamente para la recualificación de zonas céntricas, frentes costeros y entornos barriales.AbstractThis research provides scientific and methodological bases for territorial diagnostics, related to the causal effect of elevated expressways on their immediate surroundings. To achieve this, historical and normative background is used, but also, the open data processing and the use of econometric tools that measure impact. The results identify 11.893 households affected by noise pollution, reduction in buildability, reduction in property value and increase in the probability of larceny or robbery. The city of Buenos Aires is the main centrality of the region in terms of employment, production and services of the country. This condition underpins the usefulness of expressways in terms of economics and mobility; however, it faces challenges of environmental impact and quality of life, which must be prioritized within the framework of climate change and the vulnerability agenda of populations. This document also analyses the evolution of the city model with motorways, their transformations and the future possibilities of these infrastructures in urban environments. Optimizing them, replacing them with tunnels or demolishing them, are the main actions that cities are developing, specifically for the re-qualification of central areas, coastal fronts and neighborhood environments.

The current study was conducted on the city of Ramadi to find out the noise pollution represented by the sounds of generators on the residents of the city and its effect on the air purity in Ramadi city، in other words، this study aims to highlight the role of generators and their impact on increasing the level of noise pollution and air purity disturbance in the study area. Where the method of the analytical approach was followed، based on the analysis of the data obtained by the questionnaire forms of the generators owners as well as the residents of the study area. This research was divided into an introduction، a study on noise pollution and its concept and the second section dealt with the analysis and interpretation of the answers to the questionnaire forms that included (33) questions which were answered by the generators owners and the residents of Ramadi. Whereas the third section، where the sound and gas measurement device (SVAN955) (Sound Leved Metr) was used. (8) sites of various uses (commercial - residential - industrial - service) were selected and the levels of sounds were determined and compared with the relative determinants. It was clarified through the study that the city of Ramadi includes (453) generators distributing among the neighborhoods. As a result of the study that was conducted in the city of Ramadi، it was found that there are many complaints from residents of the study area which is considered (80%) of the sample size because most of the generators do not contain a silencer. The study also showed that most of the pollutants resulting from the generators are discharged with the sewage network. The study highlighted that the generator sites are located near residential homes and schools and thus have high noise pollution as well as it is considered uncivilized phenomena being not surrounded by fences، isolators or trees. The study also indicated that most of the generators are not designed for this basis (modulated) with many problems and little cost. The study showed the effect of generators on the monthly income of families، as the study showed that the highest average family income is more than (550،000) dinars per month، and the average family spends more than (55) thousand dinars per month، this amount is not including household generators.

Urban noise can interfere with avian communication through masking, but birds can reduce this interference by altering their vocalizations. Although several experimental studies indicate that birds can rapidly change their vocalizations in response to sudden increases in ambient noise, none have investigated whether this is a learned response that depends on previous exposure. Black-capped chickadees ( Poecile atricapillus ) change the frequency of their songs in response to both fluctuating traffic noise and experimental noise. We investigated whether these responses to fluctuating noise depend on familiarity with noise. We confirmed that males in noisy areas sang higher-frequency songs than those in quiet areas, but found that only males in already-noisy territories shifted songs upwards in immediate response to experimental noise. Unexpectedly, males in more quiet territories shifted songs downwards in response to experimental noise. These results suggest that chickadees may require prior experience with fluctuating noise to adjust vocalizations in such a way as to minimize masking. Thus, learning to cope may be an important part of adjusting to acoustic life in the city.
