The purpose of this research was to look at the interrelation between adult health issues in Dhaka and noise pollution.
The methodology involved a cross-sectional survey conducted in five different land use categories, with a sample size of 1,016 individuals. A validated questionnaire that focused on sources of perceived noise pollution and health issues related to noise was used to gather subjective data for the study. Objective noise pollution was evaluated using equivalent continuous sound pressure level (LA).
Findings revealed noise generated from road traffic are the predominant source of noise pollution, with Thursday evenings during the end of office hours being the noisiest period in Dhaka. All areas in Dhaka exceeded permissible noise levels, posing significant health risks to residents and workers. The study identifies critical gaps in existing noise regulation policies and enforcement.
Overall, this study underscores the urgent need for comprehensive noise pollution mitigation strategies, including innovative technologies, real-time monitoring systems, and public awareness campaigns. Further studies in diverse urban contexts are recommended to enhance the understanding of noise pollution's long-term impacts on vulnerable populations.
本研究旨在探讨达卡成人健康问题与噪音污染之间的相互关系。
该方法涉及在五种不同土地利用类别中进行的横断面调查，样本量为1016人。使用一份经过验证的问卷，该问卷聚焦于感知到的噪音污染来源以及与噪音相关的健康问题，以收集本研究的主观数据。使用等效连续声压级（LA）评估客观噪音污染。
研究结果显示，道路交通产生的噪音是噪音污染的主要来源，周四下班时间的晚上是达卡最吵闹的时段。达卡的所有区域都超过了允许的噪音水平，对居民和工人构成了重大健康风险。该研究确定了现有噪音监管政策和执法方面的关键差距。
总体而言，本研究强调迫切需要全面的噪音污染缓解策略，包括创新技术、实时监测系统和公众意识宣传活动。建议在不同城市环境中进行进一步研究，以加深对噪音污染对弱势群体长期影响的理解。
