Evaluation and Analysis of Noise Levels at High – Traffic Locations in Gusau, Nigeria

Jacob O. Ebozoje | Edwin A. Umoh



The measurement of noise levels at high-traffic intersections of Gusau town is reported in this work. Five high-traffic locations tagged LOC-A, LOC-B, LOC-C, LOC-D and LOC-E were selected and evaluated at different periods of the day using an MS6700 IEC 651, ANSI.Si.4 Type-2 Sound Level meter. Result analyses indicates that LOC-C has the highest noise level with LNP = 95 and TNI = 94, while LOC-B has the lowest noise level with LNP = 82 and TNI = 67. These noise levels imply that Gusau metropolis has an unacceptable noise level, well above the globally recommended levels of 60-65 dB(A) and the national recommended level of 82 dB(A). The paper therefore makes recommendations on minimizing these intolerable noise levels with consequences for environmental and human health in the study location.
