Noise exposures of sugar cane mill workers in Guatemala.

The data comes from only one sugar cane mill, so results may not apply to all mills in Guatemala or elsewhere. The measurements were taken over just two days during peak season, which may not represent exposures throughout the entire 7-month harvest. Third-shift workers were not included in the dataset. Some job classifications had only one dosimetry sample, which may not accurately represent all workers in that role. The study did not account for off-the-job or recreational noise exposure. Researchers did not observe workers throughout the entire shift to ensure proper dosimeter wear, though screens were inaccessible to prevent tampering.

The study was supported by the University of Northern Colorado and involved data from a commercial sugar mill. The authors state that the university's IRB approved the use of de-identified data. There is no explicit declaration of financial conflicts of interest with the mill or equipment manufacturers in the provided text, though the company implemented changes based on the findings.

Do not assume these exposure levels apply to all sugar mills or all jobs within this mill. The data is from a single facility during peak season, and only two job roles were below safety limits. Furthermore, the study measures noise exposure risk, not actual hearing loss outcomes in these workers.
