【摘要】：對18名園林工人操作背負式割灌機和側(cè)掛式割灌機作業(yè)的噪聲聲級進行實地測量,得出了園林工人在使用打草繩、2齒刀具、4齒刀具和40齒刀具進行割灌作業(yè)時每個工作日的噪聲暴露劑量。根據(jù)園林工人的作業(yè)習慣,對兩種割灌機使用不同刀具切割不同植株的作業(yè)噪聲分別進行檢測記錄,得出了兩種割灌機在怠速空轉(zhuǎn)、低速作業(yè)和高速作業(yè)狀態(tài)中的聲級和頻率。對暴露在割灌機噪聲下的園林工人進行腦電測量,對比腦電α和β波頻帶的平均功率譜密度比值R,分析了噪聲對園林工人心理負荷的影響,對園林綠化部門提出了噪聲控制的建議措施。
[Abstract]:The noise level of 18 garden workers operating on-load and side-mounted cutters was measured on the spot. The results showed that the garden workers were using straw rope and 2-tooth cutting tools. Noise exposure dose per working day for 4-tooth and 40-tooth cutting tools. According to the working habits of garden workers, the noise of cutting different plants with different cutting tools was detected and recorded, and the sound level and frequency of the two cutting machines in idle, low speed and high speed working conditions were obtained. The electroencephalogram (EEG) of garden workers exposed to the noise of the cutting machine was measured. The average power spectral density ratio R of the frequency band of EEG 偽 and 尾 was compared, and the influence of noise on the psychological load of garden workers was analyzed. The suggestions of noise control for garden greening department were put forward.
