The study focuses occupational health hazards among traffic police in Guwahati, the fastest growing city inNorth East India. 45 traffic police from 15 traffic points were met with a questionnaire at their convenient time. Noise level was measured with the help of a sound level meter during busy hours on working days in January and February’2017. 50 common men were also asked about problems from noise and air pollution. Secondary data related to level of air pollutants (PM10, SO2 and NO2) in 6 stations were collected from Pollution Control Board, Assam. Selected traffic people were found to be disturbed by respiratory problems, regular body pain, asthma and headache. Dust was found to be the common disturbing factor whereas noise was the most irritating factor in starting and end of school/office timings. Noise level in all traffic points were above desirable limit prescribed for commercial area, i.e., 65dB. Noise levels in a few traffic points recorded more than 80dB. Traffic jam and irritating horn of vehicles are big factors of noise pollution in Guwahati. Average level of PM10, SO2 and NO2 were 85 µg/m3, 7 µg/m3 and 15 µg/m3 respectively. Increasing number of private vehicles along with increasing population is the main cause of increasing vehicular pollution in Guwahati city. Government initiatives for better health and service in terms of monitoring of vehicles at regular intervals for noise and different pollutants, construction of toilets and suitable shelter places, provision of appropriate aid/ mask will be helpful for health and service of traffic people. Workshops/ programs and regular health check-ups for traffic personnel can bring positive change to occupational health.

Commercial activities are mostly centralized to main markets in many towns and cities of the Northern part of Nigeria. Such central markets constitute the noisiest part of the towns. Yet, there is no evidence that the workers and traders in such markets are aware of the challenges excessive noise pollution pose to their health. This problem serves as the basis for this research, which investigated the major source of noise pollution in Kebbi central market and make recommendation to improve the wellbeing of the people in the market.The market was divided into thirteen sections based on activities. These sections were visited twice a day for two weeks to measure their sound levels. The sound level was measured with a CEM digital noise level meter with an accuracy of ±3.5dB@1KHz. Thereafter, an ergonomic observation assessment of the noisiest section was carried out. The assessment was carried out based on rapid entire body assessment (REBA) methodology. The average sound intensity in all the sections exceeded the recommended safe sound level of 40dB. However, only the sound intensity at the grain and spice milling section (89.13 dB) exceeded the noise harmfulness level of 85dB. Operators were encouraged to use ear muffs or earplugs to minimise the exposure to harmful noise level. Proper electrification of the section was also recommended to minimise the use of internal combustion engines. The findings emphasised the need for government and relevant authorities to carry out occupational safety awareness among workers in the non-formal sector of the society.

<p>Bogor Regency has an economic growth rate including the highest among cities and other districts around the Jakarta Capital Region. Regarding the condition of the vehicle population in Bogor district, the number of motorized vehicles in 2017 and 2018 experienced a growth of between 2% and 12%. In contrast to the growth rate of vehicles, the road growth rate is only 0.1% per year. Nurul Hidayah Mosque is located on Jalan Salabenda, the object of the author's research to find out how much influence the sound of motorized vehicles has on worship activities around the Nurul Hidayah mosque. In public transport car speed, motorcycle speed, and private car speed do not have a significant effect on the noise pollution produced. The noise level around the Nurul Hidayah Mosque, Jalan Salabenda Raya, Bogor Regency which has been measured the smallest is 56.4 dBA. This value exceeds the noise threshold of the Noise Level Standard Value for the Ministerial Decree, which is 55 dBA. So that it requires attention and cooperation from the government and the community to overcome the noise in the worship area. The calculation and analysis obtained is on the equation with the largest R Square value on the fourth day of the study, the third point (Sound Level Meter 3), with a contribution of 22.67%. Like the equation on the side, y = 73.251 + 0.004x<sub>1</sub>-0.311x<sub>2</sub>-0.003x<sub>3</sub>. The meaning of this equation is that if there is no decrease in the speed of motorbikes, private cars and public transport cars, the noise pollution level in SLM3 is 73,251 dBA. If there is an increase in the speed of public transport cars by 0.004, the decrease of motorbikes by 0.311, and an increase in the speed of private cars by 0.003, the noise pollution level will decrease by 0.31 dBA at SLM3.</p>

Noise Assessment

Vehicles passing by on roadways in residential areas may produce unpleasant traffic noise that affects the residents. This paper presents the traffic noise assessment of three selected residential areas located in Skudai, Johor. The objectives of this study are to evaluate traffic characteristics at selected residential areas, determine related noise indices, and assess impact of traffic noise. Traffic characteristics such as daily traffic volume and vehicle speed were evaluated using automatic traffic counter (ATC). Meanwhile, noise indices like equivalent continuous sound pressure level (LAeq), noise level exceeded 10% (L10) and 90% (L90) of measurement time were determined using sound level meter (SLM). Besides that, traffic noise index (TNI) and noise pollution level (LNP) were calculated based on the measured noise indices. The results showed an increase in noise level of 60 to 70 dBA maximum due to increase in traffic volume. There was also a significant change in noise level of more than 70 dBA even though average vehicle speed did not vary significantly. Nevertheless, LAeq, TNI, and LNP values for all sites during daytime were lower than the maximum recommended levels. Thus, residents in the three studied areas were not affected in terms of quality of life and health.

Noise pollution higher than the standard values intensifies the patients' disease and also has negative effects on hospital staff. This study aimed to determine the level of noise pollution in the Kermanshah hospitals and also to compare obtained data with national and international standards. Multifunctional sound level meter (Model CEL – 450), has been applied for determining the sound level in different parts of a hospital in 3 different time of day (morning, visiting hours (evening), and night) for working day and holiday. The highest level was on working days and it was 60.24±5.76 dB. The average noise level on holiday was 58.15±5.44 dB. Generally, the average noise level in all studied hospitals was higher than the standard levels. The results of the analyses showed that when the P=0.003, there’s a significant difference between the average noise levels on different days. According to the results of the studies, it is necessary to plan and take managerial and technical – engineering measures to reduce the noise levels to standard levels.

     The aim of this study was to evaluate the effects of noise exposure in certain residential districts in Fallujah city. Twenty-nine stations were selected and divided into two groups; the first group was located 50 to 100 metres from the main streets (quiet areas), whilst the second was located directly on the main streets. Noise levels were measured at a rate of three readings per station for different time periods for approximately sixty days in the year 2020. Mean values were taken in both the morning and evening using a portable sound level meter (Auto range, RS-232). The highest noise level was measured at Alforkan station for the morning reading (83.8 dB) within the second group, while the lowest noise level was measured at Alshohada alawla district station for the morning reading (63.2 dB) within the first group. As for the results of the daily noise level in the evening, the highest daily average (79.4 dB) was measured at Jaish al Shabi street, while the lowest daily average (56.4 dB) was at Dor Alsekak district. The total average noise levels for the morning measurements for the first and second groups were 66.7 dB and 77.2 dB, respectively, whereas those for evening measurements were 65.3 dB and 71.7 dB, respectively. According to field measurements, the average values for the noise (traffic) for the first and second groups in the morning and afternoon exceeded 68 dB, which may cause people to feel very disturbed according to the WHO guidelines on exposure to external environmental noise. In general, all the results measured in this study are above the limits allowed both locally and internationally. This is due to certain erroneous practices in daily activities in addition to the irregular spread of electric generators and commercial activities as well as heavy traffic in the city.

An undesired or hazardous outdoor sound produced by human activities is referred to as environmental noise. For example, the noise emitted through industrial activities and transportation networks such as road, rail and air traffic. In Malaysia, most of the schools located very close to the roadside and near busy places such as cities, shops, and residential areas. This study aims to analyze the environmental noise in terms of spatial and temporal analysis in two primary schools in Terengganu State. The noise monitoring had conducted in two (2) primary schools with different land use; residential area (Batu Rakit Primary School) and commercial area (Paya Bunga Primary School) on the school and non-school days by using Sound Level Meter (SLM). The spatial mapping had constructed by using SketchUp® 2018 and Surfer® version 11 software. The noise level between both study areas was significantly different based on a p-value of less than 0.05. It also surpassed the Department of Environment (DOE) of Malaysia's permitted limit, with the Equivalent Noise Level (LAeq) in residential areas being greater than in commercial areas due to traffic volume and noise from nearby activities. Lastly, the area near the roadside has higher critical noise pollution compared with the location that furthers from the roadside. In conclusion, this study is useful in creating awareness to the public about the noise pollution effect on primary school students and is also can be used for mitigation measures to have a better place for students to study.

Noise is a form of environmental damage. An increase in the background noise leads to negative consequences for the mental and physical health of people. Noise is the greatest threat to those who by virtue of their profession are forced to constantly be exposed to it. The problem of increased noise levels in the workplaces of drivers of vehicles (buses and trams) in the cities of the Irkutsk agglomeration, as well as in sections of streets with installed noise screens (areas adjacent to linear sources of noise pollution and areas of sound shadow) is considered in the article. The legal framework for noise regulation in the Russian Federation is studied. With the help of a sound level meters, instrumental measurements of the noise level at workplaces and territories equipped with protective shields were made. The calculation of statistical characteristics and standard deviations of measuring instruments was carried out in the work. An analysis of the results obtained and their comparison with established sanitary standards for their excess were conducted.

Noise pollution has increased over the past century, especially the past few decades, disturbing the integrity of natural ecosystems. Higher noise level not only harms humans, but threatens the birds. It cause reduction of bird’s species, reproductive failure and affect food availability. A comprehensive study on noise level of three pre-selected sites of Bhindawas wetland was carried out during the November 2010 and February 2011. At each site, noise level measurements were made at ten second interval for a period of 60 minutes. Equivalent continuous sound level (Leq) ware ranged between 42.45 dB(A) to 55.66 dB(A) and 42.45 to 55.66 dB(A), respectively during the November 2010 and February 2011. It was observed that the road side site which is near to the canal water inlet to wetland has more noise level (Leq ) than the standard prescribed by the Central Pollution Control Board (CPCB) for a silence zone (50 dB). The higher values of the peak noise levels (L1) was observed during the study period, which could be disturbed the birds and they fly away to the nearest water bodies.

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.

AbstractThe present research was conducted to study the urbanization of Vadodara city and to monitor the ambient noise level in the industrial, commercial, residential and silence zones of the city. A settlement map created by unsupervised classification for the land use and land cover study of Vadodara city clearly shows the increasing pattern of urbanization in its central part, which may be the result of urban sprawl due to migration of people from the rural to the urban areas. The fluctuation in ambient noise level was recorded using an A-weighted sound level meter in all the four zones of Vadodara city for 3 h at regular intervals of 15 min on 3 consecutive days at the same time. The results showed the highest equivalent noise level of 93.7 dBA in the commercial zone followed by 85.5 dBA in the industrial zone, 73.2 dBA in silence zone, and 70.2 dBA in the residential zone. The values of noise level were high in all the zones of the city increasing remarkably over the prescribed limit given in the Noise Pollution (Control and Regulation) Rules, 2000. Continuous exposure to such high level of noise may lead to detrimental effect on people.
