A NIOSH-funded pilot project is underway to evaluate both occupational and non-occupational noise exposures of persons living and working on farms in Northwest Ohio. Noise exposure monitoring is being conducted for one week during each farming season: planting, growing, and harvesting. To date, two families have completed the monitoring process, including three adolescents. Teen 1 was a high school student who assisted on the farm part time, including driving tractors and other heavy machinery. Teens 2 and 3 were home-schooled and performed some chores daily, but did not operate any machinery. The results from the study are as follows. Teen 1 wore the dosimeter a total of 130.85 hours, including 91.55 hours at school (Leq range 70.8 - 77.7 dBA). This teen performed 8.25 hours of farming (Leq range 72.8 - 80.7 dBA). Teen 2 wore the dosimeter 60.33 hours and performed 4.87 hours of farm work (Leq range 70.6 - 88.8 dBA). Teen 2 also performed nonfarm activities (Leq range 70.6 - 84.4 dBA) and wore the dosimeter one day during home schooling for 4.97 hours (Leq of 70 dBA). Teen 3 wore the dosimeter 47.68 hours and performed 4.87 hours of farm work (Leq range 66.9 - 85.0 dBA). Teen 3 also performed nonfarm activities (Leq range 74.3 - 88.4 dBA) and wore the dosimeter for 13.33 hours during home schooling (Leq range 70.6 - 82.3 dBA). No standards exist for noise exposure during agricultural operations. However, one exposure for Teen 1 would have exceed the ACGIH TLV.
