Noise Levels and Noisiness of some Power Generators in Federal College of Education Environs, Pankshin, Plateau State Nigeria

Abstract

This research was on determination of noise levels and noisiness in noys of some power generators and comparing the results to international noise regulatory bodies permissible noise limits.  Measurement of sound pressure levels from different generators rated 650 watts to 5.0kilo watts was carried out using sound level meter SL 4010 EUROLAB.  The corresponding noisiness was determined using a noy chart 150 507 using the representative frequencies of a complex sound.  The measured sound pressure levels ranged from 76 &BA to 97 dBA.  The noisiness ranged from 45.20noys to 189.06 noys.  The noise levels were higher than the international proposal for noise limit of 45 dBA aquivalent to 5.6 noy daytime and 40dBA equivalent to 3.4noys evening time.  The noise levels were above the occupational safety and Health Administration (OSHA) exposure permissible noise limit of 80dBA equivalent to 63noys and also higher than the world Health Organization (WHO) exposure permissible noise limit of 90dBA equivalent to 120.3noys.
