Abstract

Abstract Purpose – The aim of this paper is to investigate the impacts of the noise from the diesel engine power generators used for production activities in an urban environment. Design/methodology/approach – This study has used the Enterprise Edition of NoiseMap 2000 Version 2.7.1 to investigate the impacts of the noise from the diesel engines electric power generators used in a factory in Ikorodu, an urban environment in Lagos, Nigeria. Five sections of the factory with diesel engines electric power generators were considered. The immediate and distant environments covering about 10 km of the factory host environment were considered as receptors to the noise for this study. Findings – It was found out that when all the generators operate simultaneously in the factory, the ambient noise was 30.0-152.5 dB(A) with the minimum contribution within the factory being 70.0-84.4 dB(A) and the maximum contribution of 57.2-70.8 dB(A) outside the factory fence line. Though the maximum noise is 152.5 dB(A), the maximum noise of 70.8 dB(A) beyond the fence line shows a compliance with 70 dB(A) industrial and commercial area limit but breaches the 45 dB(A) and 55 dB(A) residential area limit of the World Bank. Research limitations/implications – As much as it would be desirable ambient noise level could not be measured in all the receptors’ locations covered by the modeling. However, the capability of themodeling software adopted makes this to have no negative impact on the quality of the findings of this study. Practical implications – The study will assist the public to determine the noise level safe region around diesel engine electric power generators. Originality/value – The paper highlights the challenges in which ambient noise from the use of off-grid generators used for industrial purposes could pose to the neighboring receptor environments.
