Kumasi is the capital town of Ashanti region and it has been observed that noise pollution is ever increasing. Therefore it is imperative to conduct a research of noise levels at some areas in Kumasi to ascertain its level, whether it conforms to Environmental Protection Agency (EPA ) standards. Measurements of daytime noise levels was car ried out in three bus terminals, two timber industries, three churches and three funeral gatherings using DT-8852 Precision digital sound level meter. The three bus terminals namely Kwame Nkrumah University Of Science and Technology ( KNUST) Junction, Anloga Junction and Kejetia from the research had their daytime noise levels of 78.8 dBA, 72.1 dBA and 78.3 dBA respectively. The two timber industries, company A and company B had their day time noise levels of 84.1 dBA and 82.4 dBA respectively. Day time noise levels from the Church A, Church B and the Church C were 78.3 dBA, 82.8 dBA and 81.4 dBA respectively. Funeral ground 1 recorded the highest noise level of 84 dBA, followed by funeral ground 3 of 83.6dBA then funeral ground 2 of 79.2dBA. The bus terminals, timber industries, churches and funeral gatherings had their day time noise levels exceeding the permissible levels of 70 dBA, 70 dBA, 60 dBA and 65dBA respectively by EPA standards. It is recommended that the public should be made aware of the adve rse effects of noise pollution. The Television, radio and newspaper should be used as media to promote campaign on noise levels, its effect and control.
