    ABSTRACT: A pilot project was conducted to evaluate occupational noise exposures of three families living and working on farms in Northwest Ohio. Noise exposures were measured continuously for 7 consecutive days for each participant for 1 week each during planting, growing, and harvesting seasons. The dosimeters were programmed to evaluate noise exposures using both the Occupational Safety and Health Administration (OSHA) action level and the National Institute for Occupational Safety and Health (NIOSH)/American Conference of Governmental Industrial Hygienists (ACGIH) guidelines. One family was evaluated per year and a total of nine family members (six adults and three children) participated. Adult noise exposures for on-farm activities (occupational exposures) ranged from 46.1 to 89.6 decibels on the A-weighted scale (dBA) as an 8-hour time-weighted average (8HR TWA) using the OSHA action level and from 62.6 to 92.1 dBA 8HR TWA using the NIOSH/ACGIH guidelines. Occupational noise exposures for the children ranged from 15.4 to 81.2 dBA 8HR TWA using the OSHA action level and from 42.4 to 85.5 dBA 8HR TWA using the NIOSH/ACGIH guidelines. Six of 45 exposures among the adults and none of the 11 exposures among the children exceeded the OSHA action level. In addition, 10 of 45 exposures among the adults and 1 of 11 exposures among the children exceeded the NIOSH/ACGIH guidelines. The results of this pilot project indicate noise exposures among farm families can exceed recommended levels.

    ABSTRACT: Noise exposure assessment monitoring was conducted for a farm family during each of the three farm seasons, harvesting, growing, and planting. Sound exposure levels for each participant were compared to the OSHA-PEL and ACGIH-TLV. None of the participants exposure, during any task exceeded the OSHA-PEL of 90 dB(A) 8h-TWA. The adolescent in the study was exposed to noise in excess of the ACGIH-TLV during one farming event. The farmer was exposed to noise in excess of the ACGIH-TLV on 7 of 22 farming days and during various tasks. Hearing protection was not used by any of the participants. The findings confirm that if farmers were regulated as other occupations, farm workers would have to be included in a hearing protection program.
