This study was performed to evaluate the differences in noise level produced by an eccentric press, during the manufacturing of metallic closures for steel cans. The primary objective of the study was to establish a rank of sound intensity level and sound power level as well as the global noise level emitted by this particular press. Ten different areas in the surface surrounding the press were evaluated regarding both the sound power and the sound intensity of each measurement. Each site was measured twice to increase accuracy. The 10 areas sampled were sweeping using intensity’s probe. We have found the surface area to demonstrate the lowest noise level was at S1 and the highest one was at S10. In conclusion, our study demonstrates adequately the global noise level as well as in specific sites, indicating area requiring special treatment for noise reduction in this environment.
