Abstract
One company that has a risk of hearing loss is PT. X engaged in the supply, processing and distribution of steel and ready‑mixed materials for construction, electricity, mining, telecommunication and transportation industries. Location of noise intensity there are 4 parts that is part of iron pole, elbow, pipe and work shop. The purpose of this study was to determine the relationship of individual characteristics and noise intensity with subjective hearing loss to workers in PT. X..The type of this research is analytic research with cross sectional design. Population in this study are all workers in unit production of PT. X as many as 157 people with a sample of 61 people. The sampling technique is simple random sampling. The study was conducted in January ‑ October. The data were analyzed univariate using frequency and bivariate distribution using Chi‑Square statistical test with significance level 95% α = 0,05. The results showed less than half (49.2% of respondents subjected to subjective hearing loss. Less than half (39.3%) of respondents were at risk. More than half (68.9%) of respondents have long worked. More than half (68.9%) had less intensity than NAB (<85 dB). More than half (60.7%) of respondents did not use ear protective equipment. There is a significant relationship of age, length of service, noise intensity, ear protection with subjective hearing loss in PT. X .It is expected that the company minimizes noise intensity by using silencers. The sound‑proofing device can use the barrier wall between the machine and the worker or the silencer can be mounted on the sound source on the machine and it is expected that the company provides clear rules with sanctions for workers who do not use ear protection.
