割灌机作业噪声及其对园林工人脑波的影响
发布时间：2019-03-07 11:44
【摘要】：对18名园林工人操作背负式割灌机和侧挂式割灌机作业的噪声声级进行实地测量,得出了园林工人在使用打草绳、2齿刀具、4齿刀具和40齿刀具进行割灌作业时每个工作日的噪声暴露剂量。根据园林工人的作业习惯,对两种割灌机使用不同刀具切割不同植株的作业噪声分别进行检测记录,得出了两种割灌机在怠速空转、低速作业和高速作业状态中的声级和频率。对暴露在割灌机噪声下的园林工人进行脑电测量,对比脑电α和β波频带的平均功率谱密度比值R,分析了噪声对园林工人心理负荷的影响,对园林绿化部门提出了噪声控制的建议措施。
[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 伪 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.
