The effects of noise on health and productivity represent environmental and occupational issues fororganizations, which can be mitigated by awareness of the importance and adoption of personal protective equipment (PPE). However, the analysis of noise levels and the use ofthesaid equipment are neglected in micro and small enterprises (MSE’s). The present study aimed to identify the relationship between noise levels and productivity in a small footwear company, in which two time studies were conducted: with and without the useof hearing protective devices. The result showed that noise levels have a negative effect on productivityand the existence of a real and significant difference in the operator’s productivity with and without the use of PPE.
