Abstract

This research assessed the level of health effects of noise and vibration on human health from the use of local electric generating sets. This is a common practice in most of our homes and business places in developing countries. Sample of trading places in Ekwulobia, Aguata Local Government Area, Anambra State, Nigeria were considered as case studies. In this study, a sound level and a vibration meter were employed to measure the noise and vibration levels. Information on how users perceive vibration, sound and health effects accompanied by exposure to vibration and noise was obtained and analyzed with Chi-square test at 5% significant level. The results of the analysis showed a maximum value of vibration weighted root-mean-square (WRMS) of 6.14 m/s2, and minimum of 0.01 m/s2. The maximum value of noise was at 103.46 dB(A), the minimum at 80.72 dB(A). The maximum value of WBV and noise level was shown to be higher than the recommended value. There was also a relation between the ways the users respond to vibration and noise as well as some health effects at a p-value less than 0.05. The results showed that the use of electric powered generators in the areas studied exposed users to some health risks.
