| Summary: | Industrial Noise pollution means noise pollution that is clashing and intolerable and occurs in most factories. Sound occurs in intolerable form only when it becomes offensive and when it becomes more than a limit that it is known as “noise pollution”. This study is aimed at quantifying noise pollution from industrial noise (machine, vehicle, and human-generated) at two selected manufacturing industries namely: Kash General Hardware Ltd-Factory in Kakoba Division and Ntake Bakery and Company Limited in Kamukuzi Division both in Mbarara City, Western Uganda. The machines used for manufacturing and production in these two industries were considered for the research study as well as their operators and workers. Emphasis was given to noise emitted by the individual industrial machines. The average noise equivalent level (LAeq) was studied to identify the noisy machines and to generate baseline data. A precision grade sound level meter was used to determine the various pressure levels of sound at uniform intervals of 5 m for 6 days. It was observed that noise limit values were exceeded at almost all machines based on the regulation criteria and international standards. Also, the results of this study show that noise control measures were not put in place or when provided they were not adequate in the industries surveyed. |
