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 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.

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.

Environmental noise pollution affects not only the quality of life, but it poses a serious health and social problem. The Cirrus integrating averaging sound level instrument: model CR262A was employed to determine the noise levels at the twenty-two (22) selected sampling stations. The measurement of the noise was carried out during the morning, afternoon, and evening periods, to evaluate noise pollution within the twin city.Results indicated that there is no much difference (p>0.05) in the mean noise values within the different periods of the day at each sampling station, but there is significant variation (p<0.05) in the mean noise values at each period of the day over all the sampling stations. The results of the noise measurement showed that Enerhen Junction and NNPC Complex recorded the highest and lowest overall noise values of 84.84+5.39 dB(A) and 70 .90+2.98 dB(A) respectively. The results of this survey showed that the noise values at all the measurements points within Warri and Effurun metropolitan cities and at all the periods of the day is more than the Nigeria Federal Ministry of Environment (NFMEnv) and World Health Organization (WHO) permissible limit of 55dB daily noise level criteria for residential areas. The ssurvey requires the need to enact and enforce permissible noise levels/standards for residential neighbourhoods of 55dB by relevant environmental authorities both at Federal and state levels instead of applying 90dB standard meant for regulations in industrial settings.

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.

Noise pollution is a growing problem across the world and one which many people may not be aware of the impacts on their health. The environmental noise, and in particular the road traffic noise, remains a major environmental problem affecting the health and well-being of millions of people. With this background, a comprehensive ‘noise pollution assessment study’ was undertaken for a busy traffic corridor of Ahmedabad city of India. The traffic corridor which spans around 22.25 km passes through a mix of different areas like educational, commercials and residential. A two week long field survey was carried out on this corridor during 10-23 May, 2018 at 24 locations spread over the entire corridor. The assessment reveals that the average noise level always exceeded the prescribed guidelines of World Health Organization (WHO) for the daytime noise (75 dB (A) for Industrial area, 65 dB (A) for Commercial area, 55 dB (A) for Residential area and 50 dB (A) for Silence zones), which is quite alarming. For a major portion of the traffic corridor (79.6%), even the minimum noise level was above the permissible average noise level which is a matter of great concern. The highest noise level observed was 86.0 dB (A). Clubbing the ranks of the traffic corridor segments for the noise indicators like LAeq, Lmin, Lmax, L90, L50, L10 and LNP revealed that locations like Akhbarnagar followed by Naranpura were in the nosiest. Looking to implications of the high noise levels on the human health and productivity, it is important to initiate suitable mitigation measures. The present comprehensive study brings forth the spatial and quantitative aspects of noise pollution across the busy corridor of the city which would be of great help to the civic administration in understanding the magnitude of the problem and subsequently initiate suitable mitigative measures.

Factors Associated

The aim of this study was to identify the factors associated with school refusal behavior in primary school students. Student’s self-report and teacher’s measures were implemented; and students were recruited from 20 primary schools in six districts in Selangor, Malaysia. The survey was conducted at the end of school term in 2016, with a total of 915 students from Year 4 and Year 5 participating. The sample of students had been absent from school for more than 15% of school days in the current year. Pearson correlation shows a significant relationship between academic achievement and school satisfaction toward school refusal behavior. The findings of this study suggest that academic difficulties and dissatisfaction towards school environment could be the important risk factors for school refusal behavior. The present study underscores the importance of early detection and intervention as measures to reduce school refusal. Finally, the findings imply that the role of school factors should always be taken into account in connection with school refusal behaviour.

Post Disaster

The Ranau Earthquake that struck on 5 June 2015, February 2018, and April 2021, were a new disaster in Sabah and caused many Sabahan to panic. The unpredicted disaster also caused a serious impact on all aspects of life in Sabah. The earthquake has caused severe damage to eight primary schools in the vicinity of the epicenter, although no casualties were reported. However, the disaster has deep passing psychological effects among students. In this study, we examine how the primary school teachers enabled the student to be resilient during and after the disaster. Based on the interviews with 16 primary school students, it was revealed that most of the teachers used WhatsApp to support resilience during and after the earthquake. Interviews with 16 primary school teachers revealed there were two main reasons for them to communicate with students, namely, delivering emotional aid and monitoring their stress. Based on student interviews, five content categories of emotional support were identified: caring, reassuring, emotion sharing, belonging, and distracting. The main contribution of this study is that social media can be used as a spontaneous and proactive tool for supporting the student’s resilience during and after the earthquake trauma.
