Hearing sensitivity in farmers.

  • Description:
    Hearing sensitivity was measured for tones from 1,000 through 8,000 hertz (Hz) in 534 males and 278 females who resided in rural Wisconsin and ranged in age from 16 to 85 years. The hearing sensitivity for all subjects decreased with advancing age and at higher frequencies, but hearing loss over the range most susceptible to excessive noise exposure (3,000-6,000 Hz) was much greater for males than for females at all ages. The hearing loss was greater than could be accounted for by age and was similar whether the subject was a farmer or not. The results suggested that approximately 25 percent of the males had a communication handicap due to hearing loss by age 30, and the proportion rose to 50 percent by age 50. Less than 20 percent of farmers reported consistent use of personal hearing protection in their farm-related duties. Overall, the findings suggest that men who live in rural areas, including farmers, demonstrate a high prevalence of hearing loss and associated communication problems due to excessive noise exposure. This, in turn, clearly indicates a need for intensification of educational hearing conservation programs for the rural population.
