“…In recent years, excessive noise has also gained a different characteristic besides being a factor that causes discomfort. It is observed that when people are exposed to sound waves at high intensities for long periods of time, they lose their health (Kephalopoulos et al 2014 ; Gupta et.al 2018 ; Kumar et al 2018 ; Mehdi et al 2018 ). Development of the transportation network, proliferation of motor vehicles, widespread mechanization and failures in protecting densely populated residential areas from noise due to unplanned rapid urbanization cause many problems in terms of public health.…”

In this study, it is aimed to determine and map the noise pollution levels in Safranbolu District Center, especially in the regions where motor vehicle and/or pedestrian traffic is intense. Forty-seven measurement points were selected for noise level measurements at the district center. Measurements were conducted at morning (8 a.m.–10 a.m.), lunchtime (12 p.m.–2 p.m.) and evening (6 p.m.–8 p.m.) hours of weekdays and weekends throughout the seasons of summer 2017 and winter 2018. The summer season weekdays noise level ranges from 41.3 to 71.2 dBA in the morning period, 40 to 71.2 dBA in the noon period and 40.6 to 73.1 dBA in the evening. The summer season weekend noise level ranges from 45.3 to 69.1 dBA in the morning period, 44.7 to 71.4 dBA in the noon period and 41.6 to 70.9 dBA in the evening. The result showed that the level of summer season weekday and weekend noise pollution in the morning, noon and evening is close to each other. In addition, the winter season weekdays noise level ranges from 32.3 to 68.5 dBA in the morning period, 30.8 to 73.3 dBA in the noon period and 37.4 to 72.9 dBA in the evening. The winter season weekend noise level ranges from 37.2 to 65.8 dBA in the morning period, 40 to 71.3 dBA in the noon period and 40.5 to 69.7 dBA in the evening. The result showed that the level of winter season weekdays and weekend noise pollution in the noon is generally higher than morning and evening. The obtained data are compared with the limit values specified in the Environmental Hazard Assessment and Management Regulation. The hazardous noise level, which is considered as the threshold for causing physiological problems on humans, was determined to be exceeded at many locations. This situation may cause significant negative consequences on human health, quality of life and tourism sector. Obtained data were processed, and noise pollution levels for the city of Safranbolu were mapped using a geostatistical analysis software. In total, 16 noise pollution maps were drawn for different situations (e.g., weekdays, weekend, daytime, noon, night, summer season, winter season, etc.). Obtained noise level results demonstrate that the overall quality of the acoustic environment in our study area was medium level, which means that exposure to these levels over a long period can affect human health and quality of life. Finally, the results of a survey conducted as a part of this study were given, and possible measures and suggestions to reduce these noise levels in the district down to the desired limit values were discussed.

“…The outcome showed that noise levels, sources and the period the noise level reaches its peak vary with population density. Across Specifically, studies [1,11,15] observed that relationship exists between land use and noise pollution. Non-traffic parameters, such as land use type and pattern as well as physical distance from a given source, plays an important role in assessing noise level [16,5,17].…”

Noise has an environmental challenge is increasing due to urbanization, industrialization and modernization. While residential noise pollution could have adverse effect on health and social wellbeing, little attention has been directed towards investigating the implications of spatial pattern of neighbourhood facilities on noise pollution in Nigeria. This study assessed how noise disturbance is related to spatial pattern within two neighbourhoods in Benin City, Nigeria. Structured questionnaires were used to elicit information from residents on demographics and neighbourhood characteristics while residential land-mix was observed through street mapping. Sixty-six participants were randomly selected from Government Reserved Area (GRA) and Ogbe quarters of Benin City. Result showed that the neighbourhood facilities which host commercial, transportation and industrial activities were the closest to the dwelling units while natural vegetation was the farthest. Also there was spatial variation in distribution of neighbourhood features especially the commercial and recreational areas which affects the noise exposure level. The study concludes that it is necessary to mitigate noise within residential neighbourhoods through proper land use and zoning strategies.
