An ongoing pilot project is being conducted in Northwest Ohio to assess both the occupational and nonoccupational noise exposures of farm families. The study was designed to monitor three to five family members from three families living and working on the farm for one week each during planting, growing, and harvesting season. Dosimeters were programmed to record 24 hours a day, using both the OSHA and the NIOSH parameters. The participating family members completed daily time activity logs to record all on-farm and off-farm activities. Members of the research team also conducted time activity recording. Maximum occupational exposures exceeded the NIOSH guidelines, but not the OSHA standards for the fulltime farmer. The season with the most farming time monitored was harvest (40.32 hours), and the longest working day for the farmer consisted of 11 .25 hours during planting season. The average hours per day the dosimeter was worn by the farmer was 11.51 (growing), 7.34 (planting), and 11.42 (harvesting). The farming activity with the lowest minute-time-weighted-average (Leq dBA) was operation of a nontractor vehicle for 2 hours during growing season (average Leq of 46.2 dBA). The farming activity event with the highest average Leq was planting (0.77 hour at an average Leq of 90.2 dBA). Repair and maintenance of equipment events ranged from 60.9 to 75.1 Leq dBA during growing and planting seasons. Planting was monitored for a total of 6.3 1 hours with event averages ranging from 81.1 to 90.2 Leq dBA. Harvesting was monitored for 12.27 hours with event averages ranging from 82.7 to 84.8 Leq dBA. Tilling and plowing by the farmer were monitored for 20.53 hours with average Leq ranging from 78.0 to 89.5 dBA during events. Noise hazardous activities (Leq > 85 dBA), including planting, plowing, and tilling, all occurred during tractor operation.
