In Poland, the problem of noise risk among farmers has been poorly recognized and underestimated by the decision-making circles. The objective of the study was to determine the relationship between exposure to noise during the whole period of employment and degree of hearing loss.
The scope of the study covered the dosimetric measurements of noise, time-schedules of farming activities, and hearing examinations in a selected group of 44 farmers. The basic acoustic parameter was the dose during the whole period of employment. The analysis of the state of hearing in private farmers was based on three mean values defined as pure tone average (PTA) for frequency high frequency average (HFA) for frequency and the Cabinet Ordinance of 2002 (mean pure tone average for frequency). The relationship between hearing loss and the dose during the whole period of employment was investigated by means of linear regression analysis.
The studies of the annual exposure to noise among private farmers showed that there is a high noise risk during the summer-autumn period, which covers three months (August, September, October). The degree of hearing impairment significantly increased with age and the dose during the whole period of employment.
The results of the study allow predicting the upward tendency to hearing loss during occupational noise exposure of farmers to.
在波兰，农民面临的噪声风险问题在决策层中未得到充分认识且被低估。本研究的目的是确定整个就业期间的噪声暴露与听力损失程度之间的关系。
研究范围包括对44名选定农民进行噪声剂量测量、农业活动时间表记录以及听力检查。基本声学参数是整个就业期间的剂量。对个体农民听力状况的分析基于三个平均值，分别定义为频率的纯音平均（PTA）、高频平均（HFA）以及2002年内阁法令规定的平均值（频率的平均纯音平均）。通过线性回归分析研究听力损失与整个就业期间剂量之间的关系。
对个体农民年度噪声暴露的研究表明，夏秋季节（包括八月、九月、十月这三个月）存在较高的噪声风险。听力损伤程度随年龄以及整个就业期间的剂量显著增加。
研究结果有助于预测农民在职业噪声暴露期间听力损失呈上升趋势。
