This study focused on urban noise pollution in the Kumasi Metropolitan Assembly, Ghana, examining its implications for public health and quality of life. Five submetropolitan areas: Subin, Bantama, Manhyia North, Manhyia South and Nhyiaeso were selected to represent different neighbourhood types: commercial, residential and mixed-use zones. Ambient noise levels were monitored using a JD-801A sound level meter. Generally, the noise level ranged between 51.86 and 82.87 dB. Manhyia South recorded the highest average noise, ranging from 58.65 to 82.87 dB, and Nhyiaeso recorded the lowest, ranging from 51.86 to 74.83 dB. Commercial areas had the highest noise levels due to overcrowded areas, traders and purchasers, deafening noise from public address systems, and overwhelming honking from vehicles. The study also revealed average noise levels across all five submetros significantly exceeded the WHO 2018 Environmental Noise Guidelines, posing a potential health threat, including cardiovascular diseases, sleep disruption and cognitive impairment. The findings emphasised the urgent need for regulatory enforcement, spatial noise planning and community-based noise mitigation strategies under the oversight of the EPA Ghana.
本研究聚焦于加纳库马西大都会区的城市噪声污染，考察其对公众健康和生活质量的影响。选取了五个次都市区域：苏宾、班塔马、曼哈伊亚北区、曼哈伊亚南区和尼耶埃索，以代表不同的邻里类型：商业区、住宅区和混合用途区。使用JD - 801A声级计监测环境噪声水平。总体而言，噪声水平在51.86至82.87分贝之间。曼哈伊亚南区记录的平均噪声最高，范围为58.65至82.87分贝，而尼耶埃索记录的最低，范围为51.86至74.83分贝。商业区的噪声水平最高，原因包括区域拥挤、商人和购买者众多、公共广播系统发出的震耳欲聋的噪声以及车辆的大量鸣笛。该研究还表明，所有五个次都市区域的平均噪声水平均显著超过了世界卫生组织2018年环境噪声指南，对健康构成潜在威胁，包括心血管疾病、睡眠干扰和认知障碍。研究结果强调，在加纳环境保护局的监督下，迫切需要加强监管执法、进行空间噪声规划以及制定基于社区的噪声缓解策略。
