Noise remains a nuisance which impacts negatively on the physical, social and psychological wellbeing of man. It aggravates chronic illnesses like hypertension and other cardiopulmonary diseases. Unfortunately, increased activities from industrialization and technological transfers/drifts have tumultuously led to increased noise pollution in most of our fast growing cities today and hence the need for concerted efforts in monitoring and regulating our environmental noise.
To assess the equivalent noise level (Leq) in Abuja municipality and promote a simple method for regular assessment of Leq within our environment.
This is a cross-sectional community based study of the environmental Leq of Abuja municipality conducted between January 2014 and January 2016. The city was divided into 12 segments including residential, business and market areas via the Abuja Geographic Information System. The major markets were captured separately on a different scale. Measurements were taken with the mobile phone softwares having validated this with . Leq(A) were measured at different points and hours of the day and night. The average Leq(A) were classified according to localities and compared with WHO standard safety levels.
LeqD ranged 71-92dB(A); 42-79dB(A) and 69-90dB(A) in business/ parks, residential and market places respectively. The Night measurements were similar 18dB(A)-56dB(A) and the day-night Leq(A)=77.2dB(A) and 90.4dB(A) for residential and business zones.
The night noise levels are satisfactory but the day and day-night levels are above the recommended tolerable values by WHO and therefore urgently call for awareness and legislative regulations.
噪音仍然是一种公害，对人类的身体、社交和心理健康产生负面影响。它会加重高血压等慢性疾病以及其他心肺疾病。不幸的是，工业化进程加快以及技术转移/变迁导致如今在我们大多数快速发展的城市中，噪音污染急剧增加，因此需要共同努力来监测和管控环境噪音。
评估阿布贾市的等效连续A声级（Leq），并推广一种在我们的环境中定期评估Leq的简单方法。
这是一项基于社区的横断面研究，于2014年1月至2016年1月期间对阿布贾市的环境Leq进行研究。通过阿布贾地理信息系统将该市划分为12个区域，包括居民区、商业区和市场区。主要市场在不同比例尺下单独绘制。使用经过验证的手机软件进行测量。在白天和夜晚的不同时间点测量Leq（A）。根据不同区域对平均Leq（A）进行分类，并与世界卫生组织的标准安全水平进行比较。
商业区/公园、居民区和市场的LeqD范围分别为71 - 92dB（A）；42 - 79dB（A）和69 - 90dB（A）。夜间测量结果类似，为18dB（A） - 56dB（A），居民区和商业区的日夜间Leq（A）分别为77.2dB（A）和90.4dB（A）。
夜间噪音水平令人满意，但白天和日夜间噪音水平高于世界卫生组织建议的可容忍值，因此迫切需要提高认识并制定法律法规。
