Noise is a form of pollution particularly when it is loud, causes disturbance or unpleasant to hearing. The ecosystem is designed to be a habitat for all the organisms and the physical environment with which they interact but human activities are numerous and tend to interfere with the environment. This paper tends to compare the ambient noise level with the weighted decibels of sounds emanating from some cement manufacturing equipment like impact crushers, limestone & shale crushing machine, clink crushers, raw meal homogenizing machines, and some earth moving equipment within the industrial environment as perceived by our ears. It further focuses on the characterization of the noise from its source and measuring sound travelling through the air emitted by industrial machines using acoustic sound level meters. Field data were obtained from the three selected manufacturing plants within the geographical study areas using digital sound level meters to measure the volume and determine the ambient temperature while tachometers were used to measure some identified cement manufacturing engine operating speed at + - 5% of the indicated reading. The field result shows that the noise levels are way far above WHO standard vis a vis the average threshold of hearing for human beings. It is hoped that a regulatory approach to environmental air pollution will help to control this anomaly.
