Abstract

The COVID-19 pandemic has had profound global repercussions, leading to substantial fatalities and economic losses worldwide. However, amidst these adversities, the pandemic inadvertently offered a unique opportunity to assess the impact of reduced human activity on environmental noise levels. This study focuses on monitoring and mapping noise pollution levels at 101 locations managed by the Bhubaneswar Development Authority (BDA) in Bhubaneswar, Odisha, India, during three distinct periods: pre-COVID, during COVID-lockdown, and post-COVID. Using ArcGIS 10.2.1, noise data are spatially analysed across different zones designated by the Central Pollution Control Board (CPCB), namely Industrial, Commercial, Residential, and Silence Zones. The findings reveal a significant reduction in traffic noise during the COVID-19 lockdown period compared to both pre-COVID and post-COVID periods across all four zones. To assess the potential impact on human health, the study employs equations developed by Miedema and Vos (Acoust Soc Am 104:3432–3445, 1998, https://doi.org/10.1121/1.423927) for calculating percentages of highly annoyed individuals and estimating sleeping disorders. Additionally, Structural Equation Modeling (SEM) is applied to explore associations between noise levels and health outcomes across different time periods. Despite the significant reduction in traffic noise observed during the COVID-19 lockdown, our analysis suggests that this decrease did not have a statistically significant effect on annoyance levels (p-value: 0.0542) or sleeping disorders (p-value: 0.121). This study provides valuable insights into the unintended consequences of urban lockdowns on environmental noise pollution and their potential implications for public health and urban planning.

使用 SEM 方法绘制噪声地图以及 COVID-19 封锁对交通噪声引发的健康问题的影响
COVID-19 大流行病对全球产生了深远的影响,在世界各地造成了大量人员死亡和经济损失。然而,在这些不利因素中,大流行病无意中为评估人类活动减少对环境噪声水平的影响提供了一个独特的机会。本研究的重点是监测和绘制印度奥迪沙邦布巴内斯瓦尔发展局 (BDA) 管理的 101 个地点在 COVID 前、COVID 封锁期间和 COVID 后三个不同时期的噪声污染水平。利用 ArcGIS 10.2.1,对中央污染控制委员会(CPCB)指定的不同区域(即工业区、商业区、住宅区和安静区)的噪声数据进行了空间分析。研究结果表明,与 COVID 前和 COVID 后相比,COVID-19 封锁期间所有四个区域的交通噪声都明显降低。为了评估对人体健康的潜在影响,该研究采用了 Miedema 和 Vos 开发的方程式(Acoust Soc Am 104:3432-3445, 1998, https://doi.org/10.1121/1.423927)来计算高度烦扰人群的百分比和估计睡眠障碍。此外,研究还采用了结构方程模型 (SEM) 来探讨不同时期噪声水平与健康结果之间的关系。尽管在 COVID-19 封锁期间观察到交通噪声明显降低,但我们的分析表明,这种降低并没有对烦扰程度(p 值:0.0542)或睡眠障碍(p 值:0.121)产生有统计学意义的影响。这项研究就城市封锁对环境噪声污染的意外后果及其对公共卫生和城市规划的潜在影响提供了宝贵的见解。

期刊介绍: International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
