Abstract: A palm oil processing mill noise has negative environmental impact. The distances at which its adverse effects shall cover have to be professionally determined. This work therefore presents evaluation and modelling of environmental noise pollution from a palm oil processing mill with a maximum noise level of (110.640.69) dBA. Measurements of noise levels with respect to distance, x from the mill were considered. The linear regression method was used in analysing the data. Environmental noise models were developed by using the relevant displayed parameters. The results obtained from the models developed in this work, L (modelled) were compared with the results obtained from the physical measurements, L (measured) and there was no significant difference between them. The distances, xc in metres in which its adverse effects covered in the residential areas were0x_c82. The distances, xs in metres at which it can be sited from the residential areas were 83x_s; The results show that the equivalent continuous noise level, Leq of the mill decreased as x increased. Finally, with the existence of x, the models developed in this work are recommended to be used as more reliable tools for environmental noise impact assessments.
