Full-shift sampling, usually eight hours, is traditionally performed to assess daily occupational noise exposure. This sampling approach is inefficient, and costly for repeated, long-term exposure evaluations. This study assessed the use of four-hour sample durations and subsequent data analysis to determine daily occupational noise exposures in a foundry. The four-hour sample durations were extracted from full-shift samples and analyzed on their ability to provide valid data for estimating mean daily noise exposure levels without significantly affecting sampling precision or accuracy. Results of this study indicate four-hour sample durations can be used successfully to estimate full-shift noise exposures provided certain criteria are met. Findings of this study may reduce the sampling time and number of samples required to make decisions regarding employee noise exposures.
