The physical work environment is an environmental situation that can affect the physicality of the worker. One of the disturbances in the physical work environment is noise. Noise can cause hearing damage if the duration of exposure and the noise level has passed the threshold value. One of the poor effects of noise received by workers is hearing health problems. The research location is in a manufacturing company that produces nuts and bolts, where their production activities cause noise, especially in the manufacturing process of the head of the bolt. The noise generated is heard in the production area and has spread to the community around the company. Therefore, it is necessary to conduct noise mapping to determine the propagation of noise in the production area and the community around the company. The results showed that the noise propagation in the production area is minimum 90.2 dB and maximum of 92.3 dB. Indicates that the noise generated by production activities at the company exceeds the threshold value (85 dB). Meanwhile, the noise propagation in the residents around the factory is minimum 66.5 dB and maximum of 78.5 dB. So, it shows that the noise received by residents exceeds the threshold value (55 dB).
