摘要：Occupational exposure to noise is determined by the value of acoustic energy
and the duration of exposure - a parameter which is especially important while considering
exposure to noise among private farmers. In order to describe the duration of exposure
to noise, time-schedule measurements were carried out of occupations performed by a
selected group of 30 self-employed farmers during the whole year. Three calculated
time values were analysed: mean total monthly time of exposure (tt); mean daily time of
exposure (td) and mean monthly time of daily exposure (tm). The results of the study
showed that the highest time values of exposure to noise were observed during the
months of intensive field and transport occupations associated with harvesting of cereals
and root crops, i.e. in August, September and October; as well as during soil cultivation
and chemical treatment activities in April. This was connected with a greater number of
workdays in conditions of exposure to noise - 20–21 days on average - and a greater
duration of such workdays, often up to 11 hours a day.
