Abstract This study evaluates and compares industrial employees' noise exposure level in five selected processing and manufacturing industries in Ilorin, Nigeria. The highest and lowest average noise exposure levels are recorded in mineral crushing mills (93.16 dB(A)) and the mattress making industry (84.69 dB(A)) respectively. The study shows that there is significant difference in noise levels in the industries surveyed. High percentages of machines emitting noise above FEPA and OSHA recommendation (90 dB(A)) were found: soft drink bottling industry (83.3%), beer brewing and bottling industry (42.9%), tobacco industry (71.4%), mattress making industry (11.1%) and minerals crushing mills (87.5%). In the past 20 years, the noise levels in the soft drink bottling industry was reduced by 0.58 dB(A) and that of the brewing and bottling industry by 9.66 dB(A), but that of the mattress making industry increased by 2.69 dB(A). On the average, the noise control measures put in place have had significant impact on the noise exposure.
