WHO recommends identifying hearing loss and its causes, and implementing preventive measures to limit the adverse effects caused by noise exposure.

Mayoa Jember to determine the type of ear protection equipment needed by workers. This research was a descriptive research. The data used in this study are primary data obtained through interviews and observations. Interviews were conducted with all workers totaling 32 people. Observations were made by measuring the noise intensity at 139 measurement points scattered throughout the work area.

The results showed that most respondents experienced hearing complaints at a level that did not interfere with their activities. The noise intensity mapping shows that the noise that occurs during working hours ranges from 73.8 - 105.2 dBA and the area with a noise level above TLV is around 500 m2. The intensity during rest hours ranges from 68.2 - 101.0 dBA with an area with a noise level above TLV is less than 30 m2. The recommended APT for noise levels of 86 - 95 dBA is ear plugs, for noise 96 - 100 dBA is ear plugs / earmuffs, while for noise more than 100 dBA is dual protection, namely ear plugs and earmuffs.
