ASSESSMENT OF THE LEVELS OF NOISE POLLUTION IN NORTH BANK MARKET, IN MAKURDI USING GIS TECHNOLOGY

Abstract

Noise pollution has become a major environmental challenge in rapidly growing urban areas, especially in markets where commercial activities, traffic and human interaction are intense. This study assessed the levels and spatial distribution of noise pollution in North Bank Market, Makurdi, Benue State, using Geographic Information System (GIS) technology. Noise levels were measured at nineteen strategic locations during morning, afternoon, and evening periods using a digital sound level meter, while questionnaires were administered to capture public perception. The measurements were analyzed statistically and integrated into ArcGIS for spatial mapping and hotspot identification. Results showed that the average noise level in the market was 65 dB, exceeding recommended limits set by the World Health Organization and national guidelines. Hotspots were concentrated along major road corridors, market entrances, and densely populated trading zones, especially during peak activities. The findings reveal that noise pollution poses potential risks to public health and urban liveability. The study recommends strict noise regulation, continuous monitoring, improved market planning, and public awareness as effective mitigation strategies. GIS proved to be a valuable tool for visualizing noise dynamics and supporting environmental decision-making in urban markets.
