Abstract Construction and farming are characterized by small independently-operated enterprises; few are included in hearing loss prevention programs. This study describes perceived and measured hearing ability among construction labourers and farmers. Audiograms of 147 construction labourers and 150 farmers were statistically compared to their subjective perceived hearing ability. At the 4,000Hz frequency indicative of NIHL, a high percentage of both groups exhibited hearing loss greater than 25dB (53% of labourers and 67% of farmers). However, the relationship between perceived and actual hearing loss was poor, suggesting that systematic audiometric screening should be included in all hearing loss prevention programs.
