Studies on Control of Hazardous Noise from Portable 650 VA Power Generator

摘要

Experimental studies on the assessment and control of near-field noise levels due to the operation of a portable 650 VA power generator were undertaken at a residential building in Ara village, Moro local government, area of Kwara State. Smart sensor sound level meter AR824 (30-130 dB), meter rule and stop watch were used to measure the noise level produced at every two minutes risen time intervals for seven hundred and twenty minutes at ten different locations of one meter intervals. The background noise level of the environment was first taken and reported to be 47.60. The data obtained were analysed with Matlab R2010a. The results revealed that the 650 VA generating plant is safe for use when it is positioned at least 3 meters away to the building, offices, shops and so on.
